WARNING!  
A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD  
TO OBTAIN POSITION INFORMATION.  
CAUTION  
When showing navigation data to a position (waypoint), a GPS unit will show  
the shortest, most direct path to the waypoint. It provides navigation data to the  
waypoint regardless of obstructions. Therefore, the prudent navigator will not  
only take advantage of all available navigation tools when traveling to a way-  
point, but will also visually check to make sure a clear, safe path to the waypoint  
is always available.  
WARNING!  
When a GPS unit is used in a vehicle, the vehicle operator is solely re-  
sponsible for operating the vehicle in a safe manner. Vehicle operators  
must maintain full surveillance of all pertinent driving, boating or fly-  
ing conditions at all times. An accident or collision resulting in damage  
to property, personal injury or death could occur if the operator of a  
GPS-equipped vehicle fails to pay full attention to travel conditions and  
vehicle operation while the vehicle is in motion.

Section 1: Read Me First!  
How this manual can get you out on the road, fast!  
Welcome to the exciting world of digital sonar and GPS! We know you  
are anxious to begin navigating and finding fish, but we have a favor to  
ask. Before you grab the unit and begin installing it, please give us a  
moment or two to explain how our manual can help you get the best  
performance from your compact, color display, combination fish finder  
and mapping GPS receiver.  
First, we want to thank you for buying a Eagle sonar/GPS unit.  
Whether you are a first time user or a professional fisherman, you'll  
discover that your unit is easy to use, yet capable of handling demand-  
ing navigation and sonar tasks. When you team your unit with our cus-  
tom mapping software MapCreate6, you have an incredible combina-  
tion. You will not find another combination GPS and sonar unit with  
this much power and this many features for this price!  
Our goal for this book is to get you on the water fast, with a minimum  
of fuss. Like you, we would rather spend more time boating or fishing  
and less time reading the manual!  
So, we designed our book so that you don't have to read the whole thing  
from front to back for the information you want. At the start (or end) of  
each segment, we'll tell you what content is coming up next. If it's a  
concept you're already familiar with, we'll show you how and where to  
skip ahead for the next important topic. We've also made it easy to look  
up any tips you may need from time to time. Here's how:  
The manual is organized into 10 sections. This first section is an intro-  
®
®
duction to the FishElite 642c iGPS and SeaCharter 642cDF iGPS. It  
tells you the basics you need to know before you can make the unit look  
around and tell you where you are or look below the surface to find  
some fish.  
Section 2 will help you install your unit and the transducer . We'll show  
you how to get the MultiMedia Card (MMC) correctly installed inside  
the unit. We'll also tell you about some of the available accessories.  
Section 3 covers Basic Sonar Operation. It will show you how easy it is  
to run your unit, right out of the box. This section features a one-page  
Sonar Quick Reference. (If you've already jumped ahead and fig-  
ured out how to install the unit yourself, and you just can't wait  
any longer, turn to the Quick Reference on page 47 and head  
for the water with your unit!)

After you have gained some experience with your sonar, you will want  
to check out Section 4, which discusses more advanced Sonar Options  
and Other Features.  
When you come to a sonar menu command on the unit's screen, you can  
look it up in the manual by skimming over the table of contents, just flip-  
ping through Section 3 or scanning through the sonar options in Section 4.  
If you're having difficulty with your sonar, you can find an answer to  
the most common problems in Section 5, Sonar Troubleshooting.  
The manual switches from sonar to navigation in Section 6, which in-  
troduces you to Basic GPS Operations. This section features a one-  
page GPS Quick Reference on page 98.  
Section 6 contains short, easy-to-scan GPS lessons that follow one an-  
other in chronological order. They're all you'll need to know to find your  
way on the water quickly.  
After you've learned the basics (or if you already have some GPS expe-  
rience), you may want to try out some of the unit's many advanced  
navigation features. That brings us to Section 7, Advanced GPS Opera-  
tions. This section contains the rest of the unit's GPS command func-  
tions, organized in alphabetical order.  
When you come to a GPS menu command on the screen, you can look it  
up in the manual by skimming over the table of contents, just flipping  
through Section 6 or scanning through the command portion of Section 7.  
This unit is ready to use right out of the box, but you can fine tune and  
customize it's operation with dozens of options. Since sonar is the unit's  
key feature, we put the main sonar options in Section 4. Some options,  
such as screen brightness settings, affect both sonar and GPS opera-  
tions. We describe how to use those common options along with GPS  
options in Section 8, System Setup and GPS Setup Options. Section 8 is  
organized in alphabetical order.  
In Section 9, we go into more detail on one of the unit's most remarkable  
GPS capabilities — Searching. We'll introduce a search example in the Ba-  
sic GPS Operation section, but there are so many map items you can  
search for, we had to give this function it's own section in the manual! For  
example, did you know this unit can look up business phone numbers,  
functioning as a virtual Yellow Pages? We’ll show you how in Section 9.  
Finally, in Section 10, we offer Supplemental Material, including a list  
of the GPS datums used, warranties and customer service information.  
Now, if you're into the fine details, glance over the next segment on  
specifications to see how much sonar and GPS power your unit contains.

crystal display in your unit. This type of damage is not covered by  
the warranty. For more information, contact the factory's Customer  
Service Department. Customer service numbers are listed on the  
last page of this manual.  
How Eagle Sonar Works  
Sonar has been around since the 1940s, so if you already know how it  
works, skip down to read about the relatively new technology of GPS.  
But, if you've never owned a sonar fish finder, this segment will tell you  
the under water basics.  
Sonar is an abbreviation for SOund NAvigation and Ranging, a technol-  
ogy developed during World War II for tracking enemy submarines. A  
sonar consists of a transmitter, transducer, receiver and display. Here's  
how it locates the bottom and finds fish.  
The transmitter emits an electrical impulse, which the transducer con-  
verts into a sound wave and sends into the water. (The sound frequency  
can't be heard by humans or fish.) The sound wave strikes an object  
(fish, structure, bottom) and bounces back to the transducer, which  
converts the sound back into an electrical signal.  
The receiver amplifies this return signal, or echo, and sends it to the  
display, where an image of the object appears on the scrolling sonar

chart. The sonar's microprocessor calculates the time lapse between the  
transmitted signal and echo return to determine the distance to the  
object. The whole process repeats itself several times each second.  
Your unit can record a log of the sonar signals that scroll across the  
screen and save them to the MMC memory card. (These recordings are  
also called sonar charts or sonar graphs.) You can replay this sonar log  
in the unit using the Sonar Simulator function, or play it back on a per-  
sonal computer using our free Sonar Viewer or product emulator. The  
viewer and emulator are available for download from the Eagle web  
site, www.eaglesonar.com.  
You can save several different sonar log files, erase 'em and record new  
ones, over and over again. The size of your sonar recordings is only  
limited by the free space available on your MMC.  
How GPS Works  
You'll navigate faster and easier if you understand how the unit scans  
the sky to tell you where you are on the earth – and where you're going.  
(But if you already have a working understanding of GPS receivers and  
the GPS navigation system, skip on ahead to Section 2, Installation &  
Accessories on page 13. If you're new to GPS, read on.  
Think of your unit as a small but powerful computer. The unit includes  
a keypad and a screen with menus so you can tell it what to do. The  
screen also lets the unit show your location on a moving map, as well as  
point the way to your destination.  
This gimbal-mounted unit uses an internal antenna and receiver,  
which makes the system work like your car radio. But instead of your  
favorite dance tunes, this receiver tunes in to a couple of dozen GPS  
satellites circling the earth. (It will also listen to WAAS satellites in  
orbit, but we will delve into that in the segment introducing you to GPS  
and WAAS.)  
Your unit listens to signals from as many satellites as it can see above  
the horizon, eliminates the weakest signals, then computes its location  
in relation to those satellites. Once the unit figures its latitude and lon-  
gitude, it plots that position on the moving map shown on the screen.  
The whole process takes place several times a second!  
The performance doesn't stop there. Stored in the permanent memory  
of each unit is a basic background map of the entire world. We lock it in  
here at the factory — you can not change or erase this map.  
The background map is suitable for many navigation chores, but for  
maximum accuracy and much more detail, you need our optional map-

making software, MapCreate6 or one of our special plug-and-play  
mapping cards. Some unit features — such as searching for businesses  
and addresses — won't work without a custom MapCreate map. There  
is so much detail in our background map (and even more in MapCreate)  
that we'll describe their contents and differences in Section 3, Basic  
GPS Operations, on page 94.  
Another portion of the unit’s onboard memory is devoted to recording GPS  
navigation information, which includes waypoints, event marker icons,  
trails and routes. This lets you look back the way you came. Think of this  
data storage like the hard drive memory in a computer or a tape in a cas-  
sette tape recorder. You can save several different GPS data files, erase  
'em and record new ones, over and over again. Like any computer file,  
these GPS Data Files (file format *.usr) can be shared between Eagle  
GPS or sonar/GPS units or even personal computers.  
This unit has one more thing in common with a personal computer. Just  
as computers have a floppy disk drive for storing and exchanging files,  
the unit has a slot for an MMC (MultiMedia Card) or SD card (Secure  
Digital card) flash memory card. These solid-state memory devices are  
about the size of a postage stamp, but can hold data ranging from 8 MB  
to 1 GB in size. (Compare that to a floppy disk's 1.44 MB capacity!) This  
unit uses all that MMC space for two key GPS purposes.  
You can backup your onboard GPS Data Files by copying them to the  
MMC. Since the MMC is removable (like a floppy disk or a cassette tape),  
you can store these GPS Data Files on a personal computer equipped with  
an MMC card reader. (Or store them on a pocketful of MMCs, if you don't  
have a computer.) Our MapCreate mapping software can save, edit or  
create its own GPS Data Files, which can be copied to the MMC and then  
loaded from the MMC into the unit's memory. (NOTE: No matter where  
they come from, GPS Data Files must be loaded from the MMC into mem-  
ory before the unit can use them.)  
The other key GPS use for MMCs is storage of special high-detail, cus-  
tom maps, which you can produce on your computer with our MapCre-  
ate software. These MapCreate custom maps contain much greater de-  
tail than the basic background map. These Custom Map Files (file  
format *.lcm) can also be shared between Eagle GPS or sonar/GPS  
units and personal computers. This unit automatically reads Custom

so you can mount your unit and plug in the power. Or you might want  
to see how our text formatting makes the manual tutorials easy to  
skim. If that's the case, move on to How to Use This Manual on page  
11. But, if you want to understand the current state of satellite naviga-  
tion, look over this segment describing how GPS and its new companion  
WAAS work together to get you where you're going.  
The Global Positioning System (GPS) was launched July 17, 1995 by  
the United States Department of Defense. It was designed as a 24-  
hour-a-day, 365-days-a-year, all weather global navigation system for  
the armed forces of the U.S. and its allies. Civilian use was also avail-  
able at first, but it was less accurate because the military scrambled  
the signal somewhat, using a process called Selective Availability (SA).  
GPS proved so useful for civilian navigation that the federal govern-  
ment discontinued SA on May 2, 2000, after the military developed  
other methods to deny GPS service to enemy forces. Reliable accuracy  
for civilian users jumped from 100 meters (330 feet) under SA to the  
present level of 10 to 20 meters (about 30 to 60 feet.)  
Twenty-four satellites orbit 10,900 nautical miles above the Earth, passing  
overhead twice daily. A series of ground stations (with precisely surveyed  
locations) controls the satellites and monitors their exact locations in the  
sky. Each satellite broadcasts a low-power signal that identifies the satel-  
lite and its position above the earth. Three of these satellites are spares,  
unused until needed. The rest virtually guarantee that at least four satel-  
lites are in view nearly anywhere on Earth at all times.  
A minimum of three satellites are required to determine a 2D fix.  
The system requires signal reception from three satellites in order to  
determine a position. This is called a 2D fix. It takes four satellites to  
determine both position and elevation (your height above sea level —  
also called altitude). This is called a 3D fix.

Remember, the unit must have a clear view of the satellites in order to  
receive their signals. Unlike radio or television signals, GPS works at  
very high frequencies. These signals can be easily blocked by trees,  
buildings, an automobile roof, even your body.  
Like most GPS receivers, this unit does not have a compass or any  
other navigation aid built inside. It relies solely on the signals from the  
satellites to calculate a position. Speed, direction of travel and distance  
are all calculated from position information. Therefore, in order for unit  
to determine direction of travel, you must be moving and the faster, the  
better. This is not to say that it won’t work at walking or trolling  
speeds — it will. There will be more wandering of the data shown on  
the display.  
GPS alone is accurate for route navigation, but the U.S. Federal Avia-  
tion Administration has special aircraft navigation needs that go be-  
yond basic GPS. Consequently, the FAA has developed a program to  
boost GPS performance with its Wide Area Augmentation System  
(WAAS). The FAA commissioned the system on July 11, 2003.  
WAAS is designed to increase GPS accuracy to within 7.6 meters verti-  
cally and horizontally, but according to the FAA, it consistently comes  
within 1-2 meters horizontally and 2-3 meters vertically. It does this by  
broadcasting correction signals on GPS frequencies. Your unit auto-  
matically receives both GPS and WAAS signals.  
There are, however, some fringe areas of the U.S., including parts of  
Alaska, that do not yet receive robust WAAS coverage. Continued  
WAAS development is planned to extend WAAS coverage in the years  
to come.  
WAAS boosts the accuracy of land GPS navigation, but the system is  
designed for aircraft. The satellites are in a fixed orbit around the  
Equator, so they appear very low in the sky to someone on the ground  
in North America. Aircraft and vessels on open water can get consis-  
tently good WAAS reception, but terrain, foliage or even large man-  
made structures can sometimes block the WAAS signal from ground  
receivers.  
You'll find that using your GPS receiver is both easy and amazingly  
accurate. It’s easily the most accurate method of electronic navigation  
available to the general public today. Remember that this receiver is  
only a tool. Always have another method of navigation available, such  
as a map or chart and a compass.  
Also remember that this unit will always show navigation information  
in the shortest line from your present position to a waypoint, regardless

of terrain! It only calculates position, it can’t know what’s between you  
and your destination, for example. It’s up to you to safely navigate  
around obstacles, no matter how you’re using this product.

How to use this manual: typographical conventions  
Many instructions are listed as numbered steps. The keypad and arrow  
"keystrokes" appear as boldface type. So, if you're in a real hurry (or  
just need a reminder), you can skim the instructions and pick out what  
menu command to use by finding the boldface command text. The fol-  
lowing paragraphs explain how to interpret the text formatting for  
those commands and other instructions:  
Arrow Keys  
The arrow keys control the movement of dotted cross-hair lines on your  
mapping screen called the cursor. The arrow keys also control a hori-  
zontal line depth cursor on the sonar screen. The arrow keys help you  
move around the menus so you can execute different commands. They  
are represented by symbols like these, which denote the down arrow  
key, the up arrow, the left arrow and the right arrow: ↓ ↑ ← →.  
Keyboard  
The other keys perform a variety of functions. When the text refers to a  
key to press, the key is shown in bold, sans serif type. For example, the  
"Enter/Icons" key is shown as ENT and the "Menu" key is shown as MENU.  
Menu Commands  
A menu command or a menu option will appear in small capital letters, in  
a bold sans serif type like this: ROUTE PLANNING. These indicate that you are  
to select this command or option from a menu or take an action of some  
kind with the menu item. Text that you may need to enter or file names  
you need to select are show in italic type, such as trail name.  
Instructions = Menu Sequences  
Most functions you perform with the unit are described as a sequence of  
key strokes and selecting menu commands. We've written them in a  
condensed manner for quick and easy reading.

For example, instructions for navigating a trail would look like this:  
1. From the Map Page, press MENU|MENU|to MY TRAILS|ENT.  
2. Press to Trail 1|ENT|to NAVIGATE|ENT.  
3. You are asked to wait while it converts the trail into a route.  
4. The wait message disappears and the unit begins showing  
navigation information along the trail. Now, begin moving and  
follow your unit's directions.  
Translated into complete English, step 1 above would mean: "Start on  
the Map Page. Press the Menu key twice. Next, repeatedly press (or  
press and hold) the down arrow key to scroll down the menu and select  
(highlight) the My Trails menu command. Finally, press the Enter key."  
Step 2 would mean: "Press the down arrow key repeatedly to scroll to  
the trail named Trail 1, and press Enter. Next, press the right arrow  
key to highlight the Navigate command, then press Enter."

Section 2: Installation & Accessories  
Preparations  
You can install the unit in some other order if you prefer, but we rec-  
ommend this installation sequence:  
Caution:  
You should read over this entire installation section before drill-  
ing any holes in your vessel!  
1. Determine the approximate location for the unit, so you can plan how  
and where to route the cables for the transducer, any sensor and power.  
This will help you make sure you have enough cable length for the de-  
sired configuration.  
NOTE:  
The GPS antenna is inside the unit, so you must mount the unit in  
a location with an unobstructed view of the sky.  
2. Determine the approximate location for the transducer, any sensor  
and their cable routes.  
3. Determine the location of your battery or other power connection,  
along with the power cable route.  
4. Install the transducer and route the transducer cable to the sonar  
unit. Install the speed or temp sensor, if applicable, and route the cable  
to the unit.  
5. Route the power cable from the unit's location to an appropriate  
power source and connect it there.  
6. Connect the transducer/power cable (and any sensor cables) to the  
unit and mount the unit on the bracket.  
Transducer Installation  
These instructions will help you install your Skimmertransducer on a  
transom, on a trolling motor or inside a hull. These instructions cover  
both single- and dual-frequency Skimmer transducers. Please read all  
instructions before proceeding with any installation.  
Your Skimmer transducer typically comes packaged with a one-piece  
stainless steel bracket for mounting it to the transom of your boat. The  
optional trolling motor mount uses a one-piece plastic bracket with an  
adjustable strap. These are kick-up mounting brackets. They help pre-  
vent damage if the transducer strikes an object while the boat is mov-  
ing. If the transducer does kick-up, the bracket can easily be pushed  
back into place without tools.  
13  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Read these instructions carefully before attempting the installation.  
Determine which of the installation methods is right for your boat.  
Remember, transducer location is the most critical part of a so-  
nar installation.  
Recommended Tools and Supplies  
If you prefer the option of routing the cable through the transom, you  
will need a 5/8" drill bit. (If you intend to install an additional speed or  
temp sensor and route its cable through the same hole in the transom,  
you will need a 1" (25.4 mm) drill bit to accommodate all the cables.)  
NOTE:  
The following installation types also call for these recommended  
tools and required supplies that you must provide (supplies listed  
here are not included):  
Single-frequency transom installations  
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat-  
head screwdriver. Supplies: none.  
Dual-frequency transom installations  
Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, flat-head  
screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood  
screws.  
Single-frequency trolling motor installations  
Tools: two adjustable wrenches, flat-head screwdriver. Supplies: plastic  
cable ties.  
Shoot-through hull installations  
Tools: these will vary depending on your hull's composition. Consult  
your boat dealer or manufacturer. Other tools are a wooden craft stick  
or similar tool for stirring and applying epoxy, and a paper plate or  
piece of cardboard to mix the epoxy on. Supplies: rubbing alcohol, 100  
grit sandpaper, specially formulated epoxy adhesive available from LEI  
(see ordering information on the inside portion of the back cover). A  
sandwich hull also requires polyester resin.  
Selecting a Transducer Location  
1. The location must be in the water at all times, at all operating speeds.  
2. The transducer must be placed in a location that has a smooth flow of  
water at all times. If the transducer is not placed in a smooth flow of  
water, interference caused by bubbles and turbulence will show on the  
sonar's display in the form of random lines or dots whenever the boat is  
moving.

NOTE:  
Some aluminum boats with strakes or ribs on the outside of the  
hull create large amounts of turbulence at high speed. These boats  
typically have large outboard motors capable of propelling the boat  
at speeds faster than 35 mph. Typically, a good transom location on  
aluminum boats is between the ribs closest to the engine.  
3. The transducer should be installed with its face pointing straight  
down, if possible. For shoot-thru applications: Many popular fishing  
boat hulls have a flat keel pad that offers a good mounting surface. On  
vee hulls, try to place the transducer where the deadrise is 10° or less.  
Deadrise less than 10°  
Strakes  
Pad  
Vee pad hull (left); Vee hull (right). A pod style transducer is shown  
here, but the principle is the same for Skimmers inside a hull.  
4. If the transducer is mounted on the transom, make sure it doesn't  
interfere with the trailer or hauling of the boat. Also, don't mount it  
closer than approximately one foot from the engine's lower unit. This  
will prevent cavitation (bubble) interference with propeller operation.  
5. If possible, route the transducer cable away from other wiring on the  
boat. Electrical noise from engine wiring, bilge pumps and aerators can  
be displayed on the sonar's screen. Use caution when routing the trans-  
ducer cable around these wires.  
CAUTION: Clamp the trans-  
ducer cable to transom near  
the transducer. This will help  
prevent the transducer from  
entering the boat if it is  
knocked off at high speed.

centerline  
Hull bottom  
Hull bottom  
Align transducer centerline with hull bottom. A dual frequency  
transducer (left) and a single frequency transducer (right).  
How low should you go?  
For most situations, you should install your Skimmer transducer so  
that its centerline is level with the bottom of the boat hull.  
This will usually give you the best combination of smooth water flow  
and protection from bangs and bumps.There, however, are times when  
you may need to adjust the transducer slightly higher or lower. (The  
slots in the mounting brackets allow you to loosen the screws and slide  
the transducer up or down.) If you frequently lose bottom signal lock  
while running at high speed, the transducer may be coming out of the  
water as you cross waves or wakes. Move the transducer a little lower  
to help prevent this.  
If you cruise or fish around lots of structure and cover, your transducer  
may be frequently kicking up from object strikes. If you wish, you may  
move the transducer a little higher for more protection.  
There are two extremes you should avoid. Never let the edge of the  
mounting bracket extend below the bottom of the hull. Never let the  
bottom – the face – of the transducer rise above the bottom of the hull.  
Shoot-Thru-Hull vs. Transom Mounting  
In a shoot-thru-hull installation, the transducer is bonded to the inside  
of the hull with epoxy. The sonar "ping" signal passes through the hull  
and into the water. This differs from a bolt-thru-hull installation (often  
called "thru-hull"). In that case, a hole is cut in the hull and a specially  
designed transducer is mounted through the hull with a threaded shaft  
and nut. This puts the transducer in contact with the water.  
Typically, shoot-thru-hull installations give excellent high speed opera-  
tion and good to excellent depth capability. There is no possibility of  
transducer damage from floating objects, as there is with a transom-  
mounted transducer. A transducer mounted inside the hull can't be  
knocked off when docking or loading on a trailer.  
16

The shoot-thru-hull installation does have its drawbacks. First, some  
loss of sensitivity does occur, even on the best hulls. This varies from  
hull to hull, even from different installations on the same hull. This is  
caused by differences in hull lay-up and construction.  
Second, the transducer angle cannot be adjusted for the best fish arches  
on your sonar display. (This is not an issue for flasher-style sonars.)  
Lack of angle adjustment can be particularly troublesome on hulls that  
sit with the bow high when at rest or at slow trolling speeds.  
Third, a transducer CAN NOT shoot through wood and metal hulls.  
Those hulls require either a transom mount or a thru-hull installation.  
Fourth, if your Skimmer transducer has a built in temp sensor, it will  
only show the temperature of the bilge, not the water surface temp.  
Follow the testing procedures listed in the shoot-thru-hull installation  
section at the end of this instruction booklet to determine if you can  
satisfactorily shoot through the hull.  
Transom Transducer Assembly and Mounting  
The best way to install these transducers is to loosely assemble all of  
the parts first, place the transducer's bracket against the transom and  
see if you can move the transducer so that it's parallel with the ground.  
The following instructions sometimes vary depending on the mounting  
bracket that came with your transducer. Single frequency Skimmers  
come with a one-piece stainless steel bracket, while dual frequency  
Skimmers come with a two-piece plastic mounting bracket. Use the set  
of instructions that fits your model.  
1. Assembling the bracket.  
A. One-piece bracket: Press the two small plastic ratchets into the sides  
of the metal bracket as shown in the following illustration. Notice there are  
letters molded into each ratchet. Place each ratchet into the bracket with  
the letter "A" aligned with the dot stamped into the metal bracket. This  
position sets the transducer's coarse angle adjustment for a 14° transom.  
Most outboard and stern-drive transoms have a 14° angle.

Dot  
Align plastic ratchets in bracket.  
B. Two-piece bracket: Locate the four plastic ratchets in the trans-  
ducer's hardware package. Press two ratchets into the sides of the plastic  
bracket and two on either side of the transducer as shown in the follow-  
ing illustrations. Notice there are letters molded into each ratchet. Place  
the ratchets into the bracket with the letter "A" aligned with the align-  
ment mark molded into the bracket. Place the ratchets onto the trans-  
ducer with the letter "A" aligned with the 12 o'clock position on the  
transducer stem. These positions set the transducer's coarse angle ad-  
justment for a 14° transom. Most outboard and stern-drive transoms  
have a 14° angle.

2. Aligning the transducer on the transom.  
A. One-piece bracket: Slide the transducer between the two ratch-  
ets. Temporarily slide the bolt though the transducer assembly and  
hold it against the transom. Looking at the transducer from the side,  
check to see if it will adjust so that its face is parallel to the ground.  
If it does, then the "A" position is correct for your hull.  
If the transducer's face isn't parallel with the ground, remove the  
transducer and ratchets from the bracket. Place the ratchets into the  
holes in the bracket with the letter "B" aligned with the dot stamped  
in the bracket.  
Reassemble the transducer and bracket and place them against the  
transom. Again, check to see if you can move the transducer so it's par-  
allel with the ground. If you can, then go to step 3A. If it doesn't, repeat  
step 2A, but use a different alignment letter until you can place the  
transducer on the transom correctly.  
Ratchets

B. Two-piece bracket: Assemble the transducer and bracket as  
shown in the following figure. Temporarily slide the bolt though the  
transducer assembly but don't tighten the nut at this time. Hold the  
assembled transducer and bracket against the transom. Looking at the  
transducer from the side, check to see if it will adjust so that its face is  
parallel to the ground. If it does, then the "A" positions are correct for  
your hull.

If the transducer's face isn't parallel with the ground, remove and  
disassemble the transducer and ratchets. Place the ratchets into the  
bracket holes with the letter "B" aligned with the bracket alignment  
mark. Place them on the transducer aligned with the 12 o'clock posi-  
tion on the transducer stem.  
Reassemble the transducer and bracket and place them against the  
transom. Again, check to see if you can move the transducer so it's par-  
allel with the ground. If you can, then go to step 3B. If it doesn't, repeat  
step 2B, but use a different alignment letter until you can place the  
transducer on the transom correctly.  
3. Assembling the transducer.  
A. One-piece bracket: Once you determine the correct position for the  
ratchets, assemble the transducer as shown in the following figure.  
Don't tighten the lock nut at this time.

B. Two-piece bracket: Once you determine the correct position for the  
ratchets, assemble the transducer as shown in the figure in step 2B.  
Don't tighten the lock nut at this time.  
4. Drilling mounting holes.  
Hold the transducer and bracket assembly against the transom. The  
transducer should be roughly parallel to the ground. The trans-  
ducer's centerline should be in line with the bottom of the hull. Don't  
let the bracket extend below the hull!  
Mark the center of each slot for the mounting screw pilot holes. You  
will drill one hole in the center of each slot.  
Drill the holes. For the one-piece bracket, use the #29 bit (for the #10  
screws). For the two-piece bracket, use the #20 bit (for the #12  
screws).

5. Attaching transducer to transom.  
A. One-piece bracket: Remove the transducer from the bracket and re-  
assemble it with the cable passing through the bracket over the bolt as  
shown in the following figures.  
For single-frequency Skimmer, route cable over bolt and through  
bracket. Side view shown (left) and seen from above (right).  
Both bracket types: Attach the transducer to the transom. Slide the  
transducer up or down until it's aligned properly with the bottom of the  
hull as shown in the preceding and following figures. Tighten the  
bracket's mounting screws, sealing them with the sealant.  
Adjust the transducer so that it's parallel to the ground and tighten the  
nut until it touches the outer washer, then add 1/4 turn. Don't over  
tighten the lock nut! If you do, the transducer won't "kick-up" if it  
strikes an object in the water.

6. Route the transducer cable through or over the transom to the sonar  
unit. Make sure to leave some slack in the cable at the transducer. If  
possible, route the transducer cable away from other wiring on the boat.  
Electrical noise from the engine's wiring, bilge pumps, VHF radio wires  
and cables, and aerators can be picked up by the sonar. Use caution  
when routing the transducer cable around these wires.  
WARNING:  
Clamp the transducer cable to the transom close to the  
transducer. This can prevent the transducer from enter-  
ing the boat if it is knocked off at high speed.  
If you need to drill a hole in the transom to pass the connector through,  
the required hole size will be 5/8".  
Caution:  
If you drill a hole in the transom for the cable, make sure it is lo-  
cated above the waterline. After installation, be sure to seal the  
hole with the same marine grade above- or below-waterline seal-  
ant used for the mounting screws.  
7. Make a test run to determine the results. If the bottom is lost at  
high speed, or if noise appears on the display, try sliding the transducer  
bracket down. This puts the transducer deeper into the water, hope-  
fully below the turbulence causing the noise. Don't allow the transducer  
bracket to go below the bottom of the hull!  
Trolling Motor Bracket Installation  
(single-frequency only)  
1. Attach the optional TMB-S bracket to the transducer as shown in the  
following figure, using the hardware supplied with the transducer.  
(Note: The internal tooth washer is supplied with the TMB-S.)

tion the transducer to aim straight down when the motor is in the wa-  
ter. Tighten the strap securely.

3. Route the transducer cable alongside the trolling motor shaft. Use  
plastic ties (not included) to attach the transducer cable to the trolling  
motor shaft. Make sure there is enough slack in the cable for the motor  
to turn freely. Route the cable to the sonar unit and the transducer is  
ready for use.

Transducer Orientation and Fish Arches  
If you do not get good fish arches on your display, it could be because  
the transducer is not parallel with the ground when the boat is at rest  
in the water or at slow trolling speeds. If the arch slopes up – but not  
back down – then the front of the transducer is too high and needs to be  
lowered. If only the back half of the arch is printed, then the nose of the  
transducer is angled too far down and needs to be raised.

NOTE:  
Periodically wash the transducer's face with soap and water to re-  
move any oil film. Oil and dirt on the face will reduce the sensitivity  
or may even prevent operation.  
Shoot-Thru-Hull Preparation  
Hulls With Flotation Materials  
The transducer installation inside a fiberglass hull must be in an area  
that does not have air bubbles in the resin or separated fiberglass lay-  
ers. The sonar signal must pass through solid fiberglass. A successful  
transducer installation can be made on hulls with flotation materials  
(such as plywood, balsa wood or foam) between layers of fiberglass if  
the material is removed from the chosen area. See the figure below.  
WARNING:  
Do not remove any material from your inner hull unless  
you know the hull's composition. Careless grinding or  
cutting on your hull can result in damage that could sink  
your boat. Contact your boat dealer or manufacturer to  
confirm your hull specifications.

For example, some (but not all) manufacturers use a layer of fiberglass,  
then a core of balsa wood, finishing with an outer layer of fiberglass.  
Removing the inner layer of fiberglass and the balsa wood core exposes  
the outer layer of fiberglass. The transducer can then be epoxied directly  
to the outer layer of fiberglass. After the epoxy cures for 24 hours, fill the  
remaining space with polyester resin. When the job is finished, the hull  
is watertight and structurally sound. Remember, the sonar signal must  
pass through solid fiberglass. Any air bubbles in the fiberglass or the  
epoxy will reduce or eliminate the sonar signals.  
Testing Determines Best Location  
Ideally, the shoot-thru transducer should be installed as close to the  
transom as possible, close to the centerline. This will give you the best  
performance during high speed maneuvers.

Shoot-thru-hull transducer locations for

To choose the proper location for shoot-thru-hull mounting, follow these  
testing procedures: (You may need a helper to complete these steps.)  
1. Anchor the boat in about 30 feet of water. Add a little water to the  
sump of the boat. Plug the transducer into the sonar unit, turn it on, then  
hold the transducer over the side of the boat in the water. Adjust the sen-  
sitivity and range controls until a second bottom echo is seen on the dis-  
play. (You'll need to turn off Auto Sensitivity, Auto Depth Range and  
ASP. Try a range setting that is two to three times the water depth. The  
harder (more rocky) the bottom, the easier it will be to get a second bot-  
tom signal.) Don't touch the controls once they've been set.

Example of a second bottom signal. Unit is in 30 feet of water with  
range set at 80 feet and sensitivity set at 87 percent.  
2. Next, take the transducer out of the water and place it in the water  
in the sump of the boat, face down. (The transducer face is shown in the  
figure on the following page.) Notice how the signal strength decreases.  
25

The second bottom signal will probably disappear and the bottom signal  
intensity will likely decrease.  
3. Now move the transducer around to find the best location with the  
strongest possible bottom signal. If you find a spot with an acceptable  
bottom signal, mark the location and move on to step 4.  
If you can't get an acceptable bottom signal, try turning up the sensitivity  
by three or five keystrokes and then move the transducer around once  
more. If you find a spot that works, mark it and move on to step 4.  
If you have to turn up sensitivity by more than five keystrokes to get a  
good signal, the transducer should be mounted on the outside of the  
hull. This is especially true if you have to turn sensitivity all the way  
up to get a decent bottom signal.  
4. Most people can get good results by following steps 1 through 3, so this  
step is optional. If you want to make an extra effort to be absolutely sure  
that your selected location will work under all conditions, make a test run  
with the boat on plane and observe the bottom signal.  
You'll need to figure some way to prop the transducer into position while  
you make your test run. (A brick or two might be sufficient to hold it in  
place.)  
5. When you're satisfied with a location, mark it and proceed with the  
installation.  
Shoot-Thru-Hull Installation  
If you are installing the transducer on a hull with floatation material  
sandwiched within the hull, refer to the text "Hulls With Flotation Ma-  
terials" beginning on page 24.  
1. Make sure the area is clean, dry and free of oil or grease, then sand  
both the inside surface of the hull and the face of the transducer with  
100 grit sandpaper. The sanded hull area should be about 1-1/2 times  
the diameter of the transducer. The surface of the hull must be flat so  
the entire transducer face is in contact with the hull prior to bonding.  
After sanding, clean the hull and transducer with rubbing alcohol to  
remove any sanding debris.

Epoxy transducer to hull.  
WARNING:  
Use only the epoxy available from LEI. It has been for-  
mulated to work with these installation procedures.  
Other epoxy types may be too thin or may not cure to the  
right consistency for optimum transducer performance.  
2. The epoxy consists of the epoxy itself and a hardener. Remove the  
two compounds from the package and place them on the paper plate.  
Thoroughly stir the two compounds together until the mixture has a  
uniform color and consistency. Do not mix too fast or bubbles will form  
in the epoxy. After mixing, you have 20 minutes to complete the in-  
stallation before the epoxy becomes unworkable.  
Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face of  
the transducer as shown in the previous figure. Make sure there are no  
air pockets in the epoxy layer! Then, apply the remaining epoxy to the  
sanded area on the hull.  
3. Press the transducer into the epoxy, twisting and turning it to force  
any air bubbles out from under the transducer face. Stop pressing when  
you bottom out on the hull. When you're finished, the face of the trans-  
ducer should be parallel with the hull, with a minimum amount of ep-  
oxy between the hull and transducer.  
4. Apply a weight, such as a brick, to hold the transducer in place while  
the epoxy cures. Be careful not to bump the transducer while the epoxy  
is wet.  
27  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Leave the weight in place for a minimum of three hours. Allow the ep-  
oxy to cure for 24 hours before moving the boat.  
5. After the epoxy has cured, route the cable to the sonar unit and it's  
ready to use.  
Speed/Temperature Sensors  
This unit can accept as many as two temperature sensors, which can be  
used to monitor the temperature of surface water, a live well or some  
other location. These units can also accept an optional speed sensor for  
showing speed and distance traveled. However, you can only use one ac-  
cessory at a time. If you would like to use a speed sensor and a second  
temperature sensor at the same time, you will need a combination device.  
NOTE:  
This unit is packed with a transducer containing a built-in temp sensor.  
The SeaCharter package also includes a speed sensor. If you have a  
FishElite 642c and want a speed sensor or additional temp sensor, see  
the Accessory Ordering Information in the back of this manual.  
If a second temp sensor is used, it must be the model TS-2U. This  
model has a fixed electronic address which designates it as the second  
of two temp sensors. Dual temperatures are only displayed on the Full  
Chart page. The Large Digital page will only display the primary tem-  
perature sensor. See the following wiring diagram for temperature and  
speed sensor combinations.

Optional Speed Sensor Installation  
All the units in this series can display speed and distance traveled, but  
only the SeaCharter 642cDF iGPS comes packed with a speed sensor. If  
you wish to purchase an optional additional sensor for your unit, refer  
to the accessory ordering information inside the back cover of this  
manual. The following instructions describe how to install the speed  
sensor.  
Recommended tools for this job include: drill, 5/8" drill bit, 1/8" drill bit for  
pilot holes, screwdriver. Required supplies for this job include: four #8  
stainless steel wood screws (3/4" long), high quality, marine grade above-  
or below-waterline sealant.  
First find a location on the boat's transom where the water flow is smooth-  
est. Don't mount the sensor behind strakes or ribs. These will disturb the  
water flow to the speed sensor. Make sure the sensor will remain in the  
water when the boat is on plane.  
29  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Make sure the location does not interfere with the boat's trailer. Usually,  
the sensor is mounted about one foot to the side of the transom's center-  
line.  
Once you have determined the proper location for the unit, place the  
sensor on the transom. The bottom of the bracket should be flush with  
the hull's bottom. Using the sensor as a template, mark the hull for the  
screw's pilot holes. Drill four 1/8" holes, one in each end of the slots.  
Mount the sensor to the hull using #8 stainless steel wood screws (not  
included). Use a high quality, marine grade above- or below-waterline  
sealant to seal the screws. Make sure the sensor is flush with the bot-  
tom of the hull and tighten the screws.  
Good location  
Stern view showing good location for mounting sensor on transom.  
If the base of the transom has a radius, fill the gap between the tran-  
som and the sensor with the sealant. This will help ensure smooth wa-  
ter flow.

If you need to drill a hole in the transom to pass the connector through,  
the required hole size is 5/8".  
Caution:  
If you drill a hole in the transom for the cable, make sure it is lo-  
cated above the waterline. After installation, be sure to seal the  
hole with the same marine grade above- or below-waterline seal-  
ant used for the screws.

The sensor is now ready for use. Connect the sensor to the accessory  
socket on the back of your unit. If you have any questions concerning  
the installation of the sensor, please contact your local boat dealer.  
Power Connections  
The unit works from a 12-volt battery system. For the best results, at-  
tach the power cable directly to the battery. You can attach the power  
cable to an accessory or power buss, however you may have problems  
with electrical interference. Therefore, it's safer to go ahead and attach  
the power cable directly to the battery.  
Caution:  
When using the unit in a saltwater environment, we strongly rec-  
ommend that you shut off the power supply to the power cable when  
the unit is not in use. When the unit is turned off but still connected  
to a power supply, electrolysis can occur in the power cable plug.  
This may result in corrosion of the plug body along with the electri-  
cal contacts in the cable and the unit's power socket.  
In saltwater environments we recommend you connect the power  
cable to the auxiliary power switch included in most boat designs.  
If that results in electrical interference, or if such a switch is not  
available, we recommend connecting direct to the battery and in-  
stalling an inline switch. This will let you shut off power to the  
power cable when the unit is not in use. When you are not using  
the unit, you should always shut off power to the power cable, es-  
pecially when the power cable is disconnected from the unit.  
If possible, keep the power cable away from other boat wiring, espe-  
cially the engine's wires. This will provide the best isolation from elec-  
trical noise. If the cable is not long enough, splice #18 gauge wire onto  
it. The power cable has two wires, red and black. Red is the positive  
lead, black is negative or ground. Make sure to attach the in-line fuse  
holder to the red lead as close to the power source as possible.  
For example, if you have to extend the power cable to the battery or  
power buss, attach one end of the fuse holder directly to the battery or  
power buss. This will protect both the unit and the power cable in the  
event of a short. It uses a 3-amp fuse.

a fused accessory or power buss.  
If a malfunction happens inside the unit, extensive dam-  
age can occur if the enclosed fuse is not used. As with all  
electrical devices, this unit could be damaged to a point  
that it is unrepairable and could even cause harm to the  
user when not properly fused.  
CAUTION:  
Failure to use the enclosed 3-amp fuse will void your warranty! For  
a replacement, use a type 3AG 3-amp fuse.  
This unit has reverse polarity protection. No damage will occur if the  
power wires are reversed. However, the unit will not work until the  
wires are attached correctly.  
GPS Internal Antenna  
The unit has a built-in 12-parallel channel GPS + WAAS antenna.  
NMEA Cable Connections  
NMEAis a standard communications format for marine electronic  
equipment. For example, an autopilot can connect to the NMEA inter-  
face on the unit and receive positioning information. The unit is capable  
of exchanging information with any device that transmits or receives  
NMEA 0183 data, however, a communications cable is not available for  
the unit at this time. If you need to create a NMEA 0183 connection,  
consult customer service. Service contact information is located in the  
back of this manual.  
NMEA Wiring  
To exchange NMEA data, the unit has one NMEA 0183 version 2.0  
communication port. Com port one (Com-1) can be used to receive  
32  
Download from Www.Somanuals.com. All Manuals Search And Download.  
NMEA format GPS data. The com port can also transmit NMEA format  
GPS data to another device.  
A data cable should contain three wires. Com-1 uses the yellow wire to  
transmit, the orange wire to receive and the shield wire for signal  
ground.

Mounting the Unit: Bracket or Portable  
You can install the sonar unit on the top of a dash with the supplied  
gimbal bracket. It can also be mounted on a portable power supply.  
If you use the supplied bracket, you may be interested in the optional  
R-A-Mbracket mounting system. This converts the unit's gimbal  
bracket to a swivel mount.  
33

Optional R-A-M mounting system.  
Bracket Installation  
Mount the unit in any convenient location, provided there is clearance  
behind the unit when it's tilted for the best viewing angle. This must  
be a location with a clear view of the sky, so the internal GPS  
antenna can lock-on to the satellite signals. You should also make  
sure there is enough room behind the unit to attach the power and  
transducer cables.  
Holes in the bracket's base allow wood screw or through-bolt mounting.  
You may need to place a piece of plywood on the back side of thin fiber-  
glass panels to reinforce the panel and secure the mounting hardware.  
Front  
Install the gimbal bracket. Position the bracket so the arms slope to-  
ward the front of your unit.

Drill a 1-inch (25.4 mm) hole in the dash for the power and transducer  
cables. The best location for this hole is immediately under the gimbal  
bracket location. This way, the bracket can be installed so that it covers  
the hole, holds the cables in position and results in a neat installation.  
Some customers prefer to mount the bracket to the side of the cable  
hole. It's a matter of personal preference.

Pass the power cable's bare-wire end down though the hole from the  
top. If you want, you can fill in the hole around the cables with a good  
marine sealant. (Some marine dealers stock cable hole covers to conceal  
the opening.) No matter what type of installation you prefer, be sure to  
leave enough slack in the cables to allow tilting or swiveling the unit. If  
you choose to fill in the hole, be sure to position the cables against the  
rear edge of the hole as you apply the fill material.  
Before positioning the bracket, be sure to hold the cables against the  
rear edge of the hole. Then, slide the bracket over the hole and butt the  
rear of the bracket base firmly against the cables, pinning them in  
place against the side of the hole. Finally, fasten the bracket to the  
dash. Attach the unit to the gimbal bracket using the supplied gimbal  
knobs and washers.

Portable Installation  
Like many Eagle products, this unit is capable of portable operation by  
using an optional portable power pack (PPP). The power pack and an  
optional portable transducer expand the uses for your sonar unit. The  
PPP makes it easy to use the unit on your boat or take it to the dock, on  
a float tube, on an ice fishing trip or use it as a second sonar in a  
friend's boat.  
Most LEI portable power packs can be used with eight "D" cell alkaline  
batteries. Some use an optional sealed, rechargeable battery. For in-  
formation on the PPP for your unit, see the accessory ordering informa-  
tion inside the back cover of this manual.

MMC or SD Card Memory Card Installation  
Your unit uses a MultiMedia Card to store information, such as sonar  
logs, custom maps, waypoints, trails and other GPS data. The unit can  
also use Secure Digital Cards (SD card) to store data.  
NOTE:  
Throughout this manual, we will use the term MMC, but just re-  
member your unit can use an MMC or SD card to store data.  
Both of these solid-state flash memory devices are about the size of a  
postage stamp. An SD card is slightly thicker than an MMC. As this  
manual went to press, MMCs were available in storage capacities of 8  
MB, 16 MB, 32 MB, 64 MB and 128 MB. SD cards were available in  
capacities of 8 MB, 16 MB, 32 MB, 64 MB, 128 MB, 256 MB and 1 GB.  
Additional MMC cards are available from LEI Extras. See ordering in-  
formation inside the back cover of this manual. MMCs and SD cards  
are also available at many camera and consumer electronics stores.

You can customize how the Sonar Page displays its pictures and other  
data in many ways. Your unit also includes several special sonar features  
and options that can help you better interpret the underwater scene.  
We will discuss all of those features and options in Sec. 4, but to show  
you how easy this unit is to operate, the following page contains a, 10-  
step quick reference that will cover most fish finding situations. The  
quick reference describes how your unit will operate with all sonar fea-  
tures set to default settings.

Basic Sonar Quick Reference  
1. Mount the unit and transducer. Connect the unit to electric power  
and the transducer. Make sure the MMC is installed. See complete in-  
stallation details beginning on page 13.  
2. Launch your boat.  
3. To turn on the unit, press and release PWR key.  
4. Opening screen displays Map Page. Rotate through the four main  
Page screens (Map Page, Satellite Status Page, Navigation Page, Sonar  
Page) by pressing PAGES|← → to select Page Name|EXIT. Switch  
Pages to display Sonar Page.  
5. If GPS data is desired, wait while unit locates satellites and calculates  
current position. When the unit acquires position, a tone sounds and a posi-  
tion acquired message appears.  
6. With position acquired, head for your fishing grounds. Your unit will  
automatically display digital depth and surface water temperature in  
the top left corner of the screen.  
The auto settings will track the bottom, displaying it in the lower por-  
tion of the screen. The full sonar chart will scroll from right to left,  
showing you what's under the boat as you cruise across the water. You  
can change the display by:  
Zoom in to enlarge the chart for more detail: press ZIN.  
Zoom out to return to full chart mode: press ZOUT.  
7. Watch the display for the appearance of fish symbols (or arches, if  
Fish I.D.is turned off). When you see fish symbols or arches, you've  
found fish! Stop the boat and get your lure or bait into the water at the  
depth indicated on the sonar chart.  
8. Gauge the fish depth by visually comparing the fish symbols or  
arches with the depth scale on the right side of the screen, or get a  
more accurate measure with the Depth Cursor. Press MENU|to DEPTH  
CURSOR|ENT. Press ↓ ↑ to align the cursor line with the fish arch. The  
exact depth appears in a box at the right end of the cursor line. To clear  
the cursor, press EXIT.  
9. If you are drifting at a very low speed or anchored, you are not mov-  
ing fast enough for a fish to return the tell-tale fish arch signal. As you  
drift over a fish, or as a fish swims through the transducer's signal  
cone, the fish echo will appear as a straight line suspended between the  
surface and the bottom when Fish I.D. is turned off.  
10. To turn off the unit, press and hold PWR key for three seconds.

Sonar Operations  
As you can see from the quick reference, basic operation is pretty easy, right  
out of the box. If you are a sonar novice, try operating the unit with the de-  
fault settings until you get a feel for how it is working.  
As you are learning the basics, there is one setting you might want to  
tinker with from time to time — Sensitivity.  
Sensitivity controls the unit's ability to pick up echoes. If you want to see  
more detail, try increasing the sensitivity, a little at a time. There are situa-  
tions when too much clutter appears on the screen. Decreasing the sensitivity  
can reduce the clutter and show the strongest fish echoes, if fish are present.  
As you change the sensitivity setting, you can see the difference on the chart  
as it scrolls.  
Fig. 1  
Fig. 2  
Fig. 4  
Fig. 3  
These figures show results of different sensitivity levels on the same lo-  
cation. Fig. 1: Sensitivity at 88 percent, determined by Auto Sensitivity.  
Typical of full auto mode. Fig. 2: Sensitivity set at 75 percent. Fig. 3: Sen-  
sitivity set at 50 percent. Fig. 4: Sensitivity set at 100 percent.  
You can change the sensitivity level whether you are in Auto Sensitivity  
mode or Manual Sensitivity mode. The adjustment method works the  
same in both modes, but it gives you slightly different results.  
48  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Adjusting sensitivity in Auto Sensitivity Mode is similar to manually ad-  
justing a car's speed with the accelerator pedal while cruise control is on.  
You can tell the car to run faster, but when you let off the gas the cruise  
control automatically keeps you from running slower than the minimum  
speed setting. In the unit, auto mode will let you increase sensitivity to 100  
percent, but the unit will limit your minimum setting. This prevents you  
from turning sensitivity down too low to allow automatic bottom tracking.  
When you change the setting with auto turned on, the unit will continue to  
track the bottom and make minor adjustments to the sensitivity level, with  
a bias toward the setting you selected.  
Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a  
car without cruise control — you have complete manual control of the  
car's speed. In the unit, manual mode allows you to set sensitivity at  
100 percent (maximum) or zero percent (minimum.) Depending on wa-  
ter conditions, the bottom signal may completely disappear from the  
screen when you reduce sensitivity to about 50 percent or less.  
Try adjusting sensitivity in both auto and manual modes to see how  
they work.  
To adjust sensitivity:  
1. Press MENU|ENT.  
2. The Sensitivity Control Bar appears. Press to decrease sensitivity.  
Press to increase sensitivity. When it is set at the desired level, press  
EXIT. When you reach the maximum or minimum limit, a tone sounds.

Tip:  
While you are experimenting and learning, it is possible to scramble  
the settings so the sonar picture disappears from your screen. If that  
happens, remember it is easy to switch back to full automatic opera-  
tion by restoring the default settings.  
To Restore Default Settings:  
1. Press MENU|MENU|to SYSTEM SETUP|ENT|to RESET OPTIONS|ENT.  
2. A confirmation message will appear. Press to YES|ENT. All options  
are reset and the unit reverts back to the Map Page at the 4000-mile  
zoom range. Recorded sonar logs or GPS data will be unchanged.  
Fish Symbols vs. Full Sonar Chart  
You may have noticed in the quick reference we used fish arches in full  
sonar chart mode for our example and not the popular Fish I.D.fish  
symbol feature. Here's why.  
Fish I.D. is an easier way for a sonar novice to recognize a fishy signal  
return when he sees it. However, locating fish by symbol only has some  
limitations.  
Your sonar unit's microprocessor is remarkably powerful, but it can be  
fooled. Some of the echoes calculated to be fish could be tree limbs or tur-  
tles! To see what's under your boat in maximum detail, we recommend  
you turn off Fish I.D. and begin learning to interpret fish arches.  
Fish I.D. is most handy when you are in another part of the boat or per-  
forming some task that prevents you from watching the sonar screen.  
Then, you can turn on Fish I.D. and the audible fish alarm. When that  
lunker swims under your boat, you will hear it!  
Fish I.D. can also be useful when you want to screen out some of the  
sonar detail gathered by your unit. For example, in one case fisherman  
in San Francisco Bay saw clouds of clutter in the water but no fish  
arches. When a down rigger was pulled up, it brought up several small  
jellyfish. The fisherman switched their sonar to Fish I.D., which  
screened out the schools of jellyfish and clearly showed the game fish  
there as fish symbols.  
The sonar options section discusses Fish I.D., fish alarms and other  
features in greater detail.

Section 4: Sonar Options & Features  
ASP(Advanced Signal Processing)  
The ASPfeature is a noise rejection system built into the sonar unit  
that constantly evaluates the effects of boat speed, water conditions  
and interference. This automatic feature gives you the best display pos-  
sible under most conditions.  
The ASP feature is an effective tool in combating noise. In sonar terms,  
noise is any undesired signal. It is caused by electrical and mechanical  
sources such as bilge pumps, engine ignition systems and wiring, air  
bubbles passing over the face of the transducer, even vibration from the  
engine. In all cases, noise can produce unwanted marks on the display.  
The ASP feature has four settings — Off, Low, Medium and High. If  
you have high noise levels, try using the "High" ASP setting. However,  
if you are having trouble with noise, we suggest that you take steps to  
find the interference source and fix it, rather than continually using the  
unit with the high ASP setting.  
There are times when you may want to turn the ASP feature off. This  
allows you to view all incoming echoes before they are processed by the  
ASP feature.  
To change the ASP level:  
1. From the Sonar Page, press MENU|to SONAR FEATURES|ENT.  
2. Press to NOISE REJECTION|ENT.  
3. Press ↓ ↑ to select a setting, then press ENT.  
4. To return to the main page display, press EXIT|EXIT.

Alarms  
This unit has three types of sonar alarms. The first is the Fish Alarm.  
It sounds when the Fish I.D.feature determines that an echo is a  
fish.  
Another alarm is the Zone Alarm, which consists of a bar on the side of  
the screen. Any echo on the chart that appears inside this bar triggers  
this alarm.  
The last alarm is the Depth Alarm, which has both a Shallow and a  
Deep setting. Only the bottom signal will trigger this alarm. This is  
useful as an anchor watch, a shallow water alert or for navigation.  
Depth Alarms  
The depth alarms sound a tone when the bottom signal goes shallower  
than the shallow alarm's setting or deeper than the deep alarm's set-  
ting. For example, if you set the shallow alarm to 10 feet, the alarm will  
sound a tone if the bottom signal is less than 10 feet. It will continue to  
sound until the bottom goes deeper than 10 feet.  
The deep alarm works just the opposite. It sounds a warning tone if the  
bottom depth goes deeper than the alarm's setting. Both depth alarms  
work only off the digital bottom depth signals. No other targets will trip  
the alarms. The Shallow and Deep alarms can be used at the same time  
or individually.

3. Press ↑ ↓ to change the first number, then press to move the cur-  
sor to the next number and repeat until the depth is correct. Press ENT.  
4. Press to SHALLOW ALARM ENABLED|ENT. To turn on the alarm, high-  
light the SHALLOW ALARM ENABLED box and press ENT.  
To adjust and turn on the deep alarm:  
1. From the Sonar Alarms menu, press to DEEP ALARM ENABLED|to  
DEEP ALARM DEPTH|ENT.  
2. Press ↑ ↓ to change the first number, then press to move the cur-  
sor to the next number and repeat until the depth is correct. Press ENT.  
3. Press to DEEP ALARM ENABLED|ENT. To turn on the alarm, highlight  
the DEEP ALARM ENABLED box and press ENT.  
Zone Alarm  
The zone alarm is triggered when any echo passes inside the zone  
alarm bar, shown on the right side of the screen.  
To adjust and turn on the zone alarm:  
1. From the Sonar Alarms menu, press to ZONE ALARM ENABLED|to  
ADJUST ZONE|ENT.

3. To set the lower boundary for the Zone Alarm, use ← → to select LOWER,  
then press ↑ ↓ to move the bottom of the bar to the desired depth.  
4. Press EXIT|to ZONE ALARM ENABLED|ENT. Now, any echo — fish, bot-  
tom, structure — within the zone alarm's depth range will trigger the  
zone alarm. To turn off the alarm, highlight the ZONE ALARM ENABLED box  
and press ENT.

Fish Alarm  
Use the fish alarm for a distinctive audible alarm when fish or other  
suspended objects are detected by the Fish I.D.feature. Fish I.D.  
must be turned on for the Fish Alarm to work. A different tone sounds  
for each fish symbol size shown on the display.

Press EXIT repeatedly to get back to the main page display.  
Calibrate Speed  
The speed sensor can be calibrated to compensate for inaccuracies. Be-  
fore you change the setting, calculate the percentage the speed is off.  
You will enter this percentage in a moment.  
If you figure the sensor is reading 10 percent faster than actual speed,  
you will enter -10 in the calibration window. If the sensor is reading 5  
percent slower than true speed, you will enter + 5 in the window.  
A good way to gauge your speed sensor's performance is to compare its  
reading with the ground speed measured the GPS function. When you  
make a run to compare GPS ground speed to speed sensor speed, per-  
form your test in relatively calm water free of current, if possible.  
1. Press MENU|MENU|to SONAR SETUP|ENT|to CALIBRATE WATER  
SPEED|ENT.  
2. Enter the number you calculated earlier. Press ↑ ↓ to change the  
first character (+ or –), then press to move the cursor to the next  
number and repeat until the percentage is correct. Press EXIT.

Chart Speed  
The rate echoes scroll across the screen is called chart speed. The de-  
fault is maximum. We recommend you keep the default setting for most  
all fishing conditions.  
You may consider experimenting with chart speed when you are sta-  
tionary or drifting slowly. Sometimes the unit will display better im-  
ages when chart speed is adjusted to match the speed of your boat.  
If you are at anchor, ice fishing or fishing from a dock, experiment with  
a chart speed around 50 percent. If you are drifting slowly, try a chart  
speed around 75 percent. When you are stationary and a fish swims  
through the sonar signal cone, the image appears on the screen as a  
long line instead of a fish arch. Reducing the chart speed may result in  
a shorter line that more closely resembles a regular fish return.  
Sonar Page menu with Chart Speed command selected (left).  
Chart Speed Control Bar (right).  
If you experiment with chart speed, remember to reset it to maximum  
when you resume trolling or moving across the water at higher speed.  
To change chart speed:  
1. From the Sonar Page, press MENU|to CHART SPEED|ENT.  
2. The Chart Speed Control Bar appears. Press to decrease chart  
speed. Press to increase chart speed.  
3. When it is set at the desired level, press EXIT.  
ColorLine  
ColorLine lets you distinguish between strong and weak echoes. It  
paints a brighter color on targets that are stronger than a preset value.  
This allows you to tell the difference between a hard and soft bottom.  
55  
Download from Www.Somanuals.com. All Manuals Search And Download.  
For example, a soft, muddy or weedy bottom returns a weaker signal  
which is shown with a narrow, colored line (dark blue tinged with red  
or a little yellow.) Since fish are among the weakest echoes, they show  
up mostly as blue arches. A hard bottom or other relatively hard target  
returns a strong signal which causes a wider brightly colored line (red-  
dish yellow to bright yellow.)  
If you have two signals of equal size, one with red to yellow color and  
the other without, then the target with brighter color (yellow) is the  
stronger signal. This helps distinguish weeds from trees on the bottom,  
or fish from structure.  
ColorLine is adjustable. Experiment with your unit to find the Color-  
Line setting best for you.

FasTrack  
This feature automatically converts all echoes to short horizontal lines  
on the right side of the display. The graph on the rest of the screen con-  
tinues to operate normally. FasTrack gives you a rapid update of condi-  
tions directly under the boat. This makes it useful for ice fishing or  
when your are fishing at anchor. When the boat is not moving, fish sig-  
nals are long, drawn out lines on a normal chart display. FasTrack con-  
verts the graph to a vertical bar graph that with practice, makes a use-  
ful addition to fishing at a stationary location.

Fish I.D.  
The Fish I.D. feature identifies targets that meet certain conditions as  
fish. The microcomputer analyzes all echoes and eliminates surface  
clutter, thermoclines and other undesirable signals. In most instances,  
remaining targets are fish. The Fish I.D. feature displays fish symbols  
on the screen in place of actual fish echoes.  
There are several fish symbol sizes. These are used to designate the  
relative size between targets. Fish I.D. displays a small fish symbol  
when it thinks a target is a small fish and a medium fish symbol on a  
larger target and so on.

The sonar's microcomputer is sophisticated, but it can be fooled. It can  
not distinguish between fish and other suspended objects such as trot-  
lines, turtles, submerged floats, air bubbles, etc. Individual tree limbs  
extending outwards from a group of limbs is the hardest object for the  
Fish I.D. feature to distinguish from fish.  
You may see fish symbols on the screen when actually, there are no  
fish. The reverse is also true. The images on the next page show how  
Fish I.D. can actually miss fish that are present.  
Does that mean Fish I.D. is broken? No. The feature is interpreting so-  
nar returns in a specific way to help take some of the work out of read-  
ing the screen. Remember: Fish I.D. is one of the many tools we provide  
so you can analyze your sonar returns for maximum fish finding infor-  
mation. This and other features can help you successfully see beneath  
the boat under varied water and fishing conditions. So, practice with  
the unit in both the Fish I.D. mode and without to become more famil-  
iar with the feature. The default setting for Fish I.D. is off.

Frequency (SeaCharter only)  
The SeaCharter 642cDF iGPS transducer operates with both 200 kHz  
and 50 kHz. The 200 kHz frequency has a 12° cone angle and the 50  
kHz frequency has a 35° cone angle.  
The default frequency is 200 kHz, best for use in shallow water (about  
300 feet or less). This frequency is the best choice for about 80 percent  
of the fresh and salt water sport fishing applications. When you get into  
deep salt water — 300 to 500 feet or deeper — the 50 kHz frequency  
will perform better.  
The 200 kHz transducer will give you better detail and definition, but  
less depth penetration. The 50 kHz transducer will give you greater  
depth penetration, but a little less detail and less definition.  
Remember: all sonar units typically read deeper in fresh water than in  
salt water.  
There is a common exception to these rules. Some fishermen on fresh-  
water lakes (or the ocean) using downriggers like to see them on the

Ping Speed & HyperScroll  
Ping Speed controls the rate at which the transmitter and transducer  
broadcast sonar sound waves — pings — into the water. The unit has a  
default ping speed of 50 percent. At normal boating speeds, this auto-  
matically provides echoes to refresh the screen and scroll the chart at  
maximum chart speed.  
When you are running at high speeds or just want the fastest possible  
screen update, you may want to use the HyperScrollfeature. When  
67  
Download from Www.Somanuals.com. All Manuals Search And Download.  
you change the Ping Speed to any setting greater than 50 percent, the  
unit automatically enters HyperScroll mode.  
These faster ping rates allow you to maintain a high-detail picture on  
the screen. The ping rate helps the screen refresh rate and chart scroll  
speed keep pace with the speed of the boat.  
When using HyperScroll, you may also need to manually decrease the  
sensitivity for optimum performance. Depending on water depth and  
other conditions, HyperScroll may cause a second bottom echo to return  
to the transducer during the next ping cycle. This can result in a large  
amount of clutter appearing on the screen. If this occurs, decrease the  
sensitivity to a level that eliminates the clutter. When you turn Hyper-  
Scroll off, you can return to your original sensitivity level.

Set Keel Offset  
This unit measures water depth from the face of the transducer. Since  
the transducer is installed below the water surface, the distance dis-  
played by the digital depth, chart depth scale, chart cursor or fish sym-  
bols is not the exact water depth. If the transducer is 1 foot below the  
surface, and the screen shows the water depth as 30 feet, then the ac-  
tual depth is 31 feet.  
On sailboats or other large vessels with deep drafts, the distance be-  
tween the transducer installation and the keel or lower engine unit can  
be several feet. In those cases, an inexact depth reading could result in  
grounding or striking underwater structure. The Keel Offset feature  
eliminates the need for the navigator to mentally calculate how much  
water is under his keel.  
Keel Offset lets you calibrate the digital depth, chart depth scale, chart  
cursor depth and fish symbol depth displayed on the screen. To calibrate  
the depth indicators, first measure the distance from the face of the  
transducer to the lowest part of the boat. In this example, we will use 3.5  
feet. This will entered as a negative 3.5 feet, which makes the depth indi-  
cators perform as if the transducer's lower in the water than it really is.  
1. Press MENU|MENU|to SONAR SETUP|ENT|to SET KEEL OFFSET|ENT.  
2. The Keel Offset dialog box appears. Press to change the plus (+)  
sign to a minus (–) sign.  
3. Press to the first number, then press to change the number to 3.  
4. Press to the second number, then press to change the number to  
5 and press EXIT. The depth indicators now accurately show the depth  
of water beneath the keel.  
NOTE:  
If knowing the exact depth of water beneath the keel is less important,  
you can calibrate the depth indicators so that they show the actual wa-  
ter depth from surface to bottom. To do this, measure the distance  
from the face of the transducer up to the surface (the water line on the  
boat). In this example, we will use 1.5 feet. This will be entered as a  
positive 1.5 feet, which makes the depth indicators perform as if the  
transducer's higher in the water than it really is.  
1. Press MENU|MENU|to SONAR SETUP|ENT|to SET KEEL OFF-  
SET|ENT.  
2. The Keel Offset dialog box appears with a plus (+) sign at the  
front of the box.

ber to 5 and press EXIT. The depth indicators now accurately show  
the water depth from surface to bottom.  
Sensitivity & Auto Sensitivity  
The sensitivity controls the ability of the unit to pick up echoes. Sensi-  
tivity can be adjusted, because water conditions vary greatly. A low  
sensitivity level — from zero to 50 percent — excludes much of the bot-  
tom information, fish signals and other target information.  
High sensitivity levels let you see this detail, but it can also clutter the  
screen with many undesired signals. Typically, the best sensitivity level  
shows a good solid bottom signal with Colorline and some surface clutter.  
Automatic Sensitivity  
The default sensitivity mode is automatic. The unit bases the sensitiv-  
ity level on water depth and conditions. When the unit is in the auto-  
matic mode, sensitivity is automatically adjusted to keep a solid bottom  
signal displayed, plus a little more power. This gives it the capability to  
show fish and other detail.  
Situations occur when an increase or decrease in sensitivity is needed.  
An increase in sensitivity is necessary when you want to see more de-  
tail. A decrease in sensitivity will clear up the screen when it becomes  
cluttered by tiny air bubbles caused by boat wakes or wave action.  
The control bar used to adjust sensitivity up or down is the same  
whether the unit is in the automatic or manual mode. In automatic you  
can adjust sensitivity up to 100 percent, but the unit will limit your  
minimum setting. In auto, the unit will continue to make small ad-  
justments, allowing for the setting you selected.  
In manual mode, you have complete control over sensitivity with the  
ability to set it anywhere from zero to 100 percent. Once you select a  
level in manual, the unit will continue to use that exact sensitivity set-  
ting until you change it or revert to auto mode.  
To adjust sensitivity in auto mode:  
1. Press MENU|ENT.  
2. The Sensitivity Control Bar appears. Press to decrease sensitivity.  
Press to increase sensitivity. When it is set at the desired level, press  
EXIT.

Section 5: Sonar Troubleshooting  
If your unit is not working, or if you need technical help, please use the  
following troubleshooting section before contacting the factory customer  
service department. It may save you the trouble of returning your unit  
for repair. For contact information, refer to the last page, just inside the  
back cover of this manual.  
Unit won't turn on:  
1. Check the power cable's connection at the unit. Also check the wiring.  
2. Make sure the power cable is wired properly. The red wire connects  
to the positive battery terminal, black to negative or ground.  
3. Check the fuse.  
4. Measure the battery voltage at the unit's power connector. It should  
be at least 10 volts. If it isn't, the wiring to the unit is defective, the  
battery terminals or wiring on the terminals are corroded, or the bat-  
tery needs charging.  
Unit freezes, locks up, or operates erratically:  
1. Electrical noise from the boat's motor, trolling motor, or an accessory  
may be interfering with the sonar unit. Rerouting the power and trans-  
ducer cables away from other electrical wiring on the boat may help.  
Route the sonar unit's power cable directly to the battery instead of  
through a fuse block or ignition switch.  
2. Inspect the transducer cable for breaks, cuts, or pinched wires.  
3. Check the transducer and power connector. Make sure it's securely  
plugged in to the unit.  
Weak bottom echo, digital readings erratic, or no fish signals:  
1. Make sure the transducer is pointing straight down. Clean the face of  
the transducer. Oil, dirt and fuel can cause a film to form on the trans-  
ducer, reducing its effectiveness. If the transducer is mounted inside the  
hull, be sure it is shooting through only one layer of fiberglass and that it  
is securely bonded to the hull. When attaching a transducer to the inside  
of a hull, ONLY use the epoxy available from LEI (order information is  
inside the back cover). Do NOT use RTV silicone rubber adhesive or any  
other type of epoxy. The LEI epoxy is specially formulated so that it will  
cure properly for shoot-through applications.  
2. Electrical noise from the boat's motor can interfere with the sonar.  
This causes the sonar to automatically increase its discrimination or  
noise rejection feature. This can cause the unit to eliminate weaker  
signals such as fish or even structure from the display.  
81  
Download from Www.Somanuals.com. All Manuals Search And Download.  
3. The water may be deeper than the sonar's ability to find the bottom.  
If the sonar can't find the bottom signal while it's in the automatic  
mode, the digital sonar display will flash continuously. It may change  
the range to limits far greater than the water you are in. If this hap-  
pens, place the unit in the manual mode, then change the range to a  
realistic one, (for example, 0-100 feet) and increase the sensitivity. As  
you move into shallower water, a bottom signal should appear.  
4. Check the battery voltage. If the voltage drops, the unit's transmitter  
power also drops, reducing its ability to find the bottom or targets.  
Bottom echo disappears at high speeds or erratic digital read-  
ing or weak bottom echo while boat is moving:  
1. The transducer may be in turbulent water. It must be mounted in a  
smooth flow of water in order for the sonar to work at all boat speeds. Air  
bubbles in the water disrupt the sonar signals, interfering with its ability  
to find the bottom or other targets. The technical term for this is cavitation.  
2. Electrical noise from the boat's motor can interfere with the sonar.  
This causes the sonar to automatically increase its discrimination or  
noise rejection feature. This can cause the unit to eliminate weaker  
signals such as fish or even structure from the display. Try using resis-  
tor spark plugs or routing the sonar unit's power and transducer cables  
away from other electrical wiring on the boat.  
No fish arches when the Fish I.D. feature is off:  
1. Make sure the transducer is pointing straight down. This is the most  
common problem if a partial arch is displayed.  
2. The sensitivity may not be high enough. In order for the unit to dis-  
play a fish arch, it has to be able to receive the fish's echo from the time  
it enters the cone until it leaves. If the sensitivity is not high enough,  
the unit shows the fish only when it is in the center of the cone.  
3. Use the Zoom feature. It is much easier to display fish arches when  
zoomed in on a small range of water than a large one. For example, you  
will have much better luck seeing fish arches with a 30 to 60 foot range  
than a 0 to 60 foot range. This enlarges the targets, allowing the dis-  
play to show much more detail.  
4. The boat must be moving at a slow trolling speed to see fish arches.  
If the boat is motionless, fish stay in the cone, showing on the screen as  
straight horizontal lines.  
NOISE  
A major cause of sonar problems is electrical noise. This usually ap-  
pears on the sonar's display as random patterns of dots or lines. In se-  
vere cases, it can completely cover the screen with black dots, or cause  
the unit to operate erratically, or not at all.  
82  
Download from Www.Somanuals.com. All Manuals Search And Download.  
To eliminate or minimize the effects of electrical noise, first try to de-  
termine the cause. With the boat at rest in the water, the first thing  
you should do is turn all electrical equipment on the boat off. Make sure  
the engine is also off. Turn your sonar on, then turn off Noise Reject  
[also known as the ASP feature (Advanced Signal Processing)]. Sensi-  
tivity should be set at 90-95 percent. There should be a steady bottom  
signal on the display. Now turn on each piece of electrical equipment on  
the boat and view the effect on the sonar's display. For example, turn  
on the bilge pump and view the sonar display for noise. If no noise is  
present, turn the pump off, then turn on the VHF radio and transmit.  
Keep doing this until all electrical equipment has been turned on, their  
effect on the sonar display noted, then turned off.  
If you find noise interference from an electrical instrument, trolling mo-  
tor, pump, or radio, try to isolate the problem. You can usually reroute  
the sonar unit's power cable and transducer cable away from the wiring  
that is causing the interference. VHF radio antenna cables radiate  
noise when transmitting, so be sure to keep the sonar's wires away  
from it. You may need to route the sonar unit's power cable directly to  
the battery to isolate it from other wiring on the boat.  
If no noise displays on the sonar unit from electrical equipment, then  
make sure everything except the sonar unit is turned off, then start the  
engine. Increase the RPM with the gearshift in neutral. If noise ap-  
pears on the display, the problem could be one of three things; spark  
plugs, alternator, or tachometer wiring. Try using resistor spark plugs,  
alternator filters, or routing the sonar unit's power cable away from  
engine wiring. Again, routing the power cable directly to the battery  
helps eliminate noise problems. Make sure to use the in-line fuse sup-  
plied with the unit when wiring the power cable to the battery.  
When no noise appears on the sonar unit after all of the above tests,  
then the noise source is probably cavitation. Many novices or persons  
with limited experience make hasty sonar installations which function  
perfectly in shallow water, or when the boat is at rest. In nearly all  
cases, the cause of the malfunction will be the location and/or angle of  
the transducer. The face of the transducer must be placed in a location  
that has a smooth flow of water at all boat speeds. Read your trans-  
ducer owner's manual or the Installation instructions (Sec. 2) in this  
manual for the best mounting position.

Section 6: Basic GPS Operations  
This section addresses the unit's most basic GPS operations. The tuto-  
rials presented in Sec. 6 follow a chronological order. Sec. 7, Advanced  
GPS Operations, will discuss other more advanced functions and utili-  
ties. Material in Sec. 7 is arranged in alphabetical order.  
Before you turn on the unit and find where you are, it's a good idea to  
learn about the different keys, the four Page screens and how they all  
work together. BUT, if you just can't wait to get outside, turn to the  
one-page Quick Reference on page 98.

Pages  
The unit has four Page displays: Satellite Status Page, Navigation Page,  
Map Page and Sonar Page. They are accessed by pressing the PAGES key,  
then using ← → to select a Page. Clear the Pages Menu by pressing EXIT.  
Map Page display options.  
Sonar Page  
The Sonar Page displays the sonar chart, a view of the water column  
from the surface to the bottom. The chart scrolls across the screen from  
right to left, displaying echoes that represent fish, structure and the  
bottom. The Sonar Page is discussed in detail in Sec. 3. To get to the  
Sonar Page press the PAGES key, then use ← → to select SONAR.  
Satellite Status Page  
The Satellite Status Page, shown in the following images, provides de-  
tailed information on the status of the unit's satellite lock-on and posi-  
tion acquisition. To get to the Satellite Status Page press the PAGES  
key, then use ← → to select STATUS.  
No matter what Page you are on, a flashing current position indica-  
tor/question mark symbol and flashing GPS data displays indicate sat-  
ellite lock has been lost and no position is confirmed. The Satellite  
Status Page shows you the quality and accuracy of the current satellite  
lock-on and position calculation.  
WARNING:  
Do not begin navigating with this unit until the numbers  
have stopped flashing!

Satellite Status Page. The first figure (left) indicates unit has not locked  
on to any satellites and does not have a fix on its position. The second  
figure (right) shows satellite lock-on with a 3D position acquired (lati-  
tude, longitude and altitude), and WAAS reception.  
This screen shows a graphical view of the satellites in view. Each satellite is  
shown on the circular chart relative to your position. The point in the center  
of the chart is directly overhead. The small inner ring represents 45° above  
the horizon and the large ring represents the horizon. North is at the top of  
the screen. If your unit is facing north, you can use this to see which satel-  
lites are obstructed by obstacles in your immediate area.  
The GPS receiver is tracking satellites that are in bold type. The re-  
ceiver hasn't locked onto a satellite if the number is grayed out, there-  
fore it isn't being used to solve the position.  
Beneath the circular graph are the bar graphs, one for each satellite in  
view. Since the unit has twelve channels, it can dedicate one channel  
per visible satellite. The taller the bar on the graph, the better the unit  
is receiving the signals from the satellite.  
NOTE:  
One of the data display options for the Satellite Status page is Posi-  
tion Error (horizontal position error), which when selected, will ap-  
pear in one of the page's digital data boxes. Position Error will show  
the expected error from a benchmark location. If the Position Error  
is 50 feet, then the position shown by the unit is estimated to be  
within 50 feet of the actual location.  
It also gives you an indicator of the fix quality the unit currently has.  
The smaller the position error number, the more accurate the fix is.  
If the position error flashes dashes, the unit has not locked onto the  
satellites and the number shown isn't valid.

The Satellite Status Page has its own menu, which is used for setting  
various options. To access the Satellite Status Page Menu, from the  
Status Page, press MENU.  
Navigation Page  
This screen has a compass rose that not only shows your direction of  
travel, but also the direction to a recalled waypoint. To get to the Navi-  
gation Page press PAGES|← → to NAVIGATION|EXIT.  
The navigation screen looks like the one below when you are not navi-  
gating to a waypoint or following a route or trail. Your position is  
shown by an arrow in the center of the screen. Your trail history is il-  
lustrated by the line extending from the arrow. The arrow pointing  
down at the top of the compass rose indicates the current direction of  
travel (track).

Speed is the velocity you are making over the ground. If you want, you  
can customize the Speed data box to display Closing Speed instead.  
Closing Speed is also known as velocity made good. It is the speed you  
are making toward the waypoint. For instructions, see the Customize  
Page Displays entry in Sec. 8.  
Track is the heading or the current direction you are traveling. Bearing  
is the line-of-sight direction from your present position to the destina-  
tion. No matter what direction you are steering, the Bearing window  
shows the compass direction straight to the destination from your cur-  
rent location. Distance shows how far it is to your destination.  
The Off Course window shows the current cross track error. This shows  
the distance you are off-course to the side of the desired course line. The  
course line is an imaginary line drawn from your position when you  
started navigating to the destination. The course line is shown on the  
Navigation screen and Map Page screens as a red line.

Travel Time is the time it will take to reach your destination at your  
present closing speed. You can also customize the time data box to show  
Arrival Time instead. Arrival Time is the local time it will be when you  
arrive at the destination, based upon your present closing speed and  
track.  
In the preceding figure, the driver is headed northwest (a 307º track)  
toward a waypoint 307º (bearing) away. The cross track error range  
(white corridor) is 0.20 miles either side of the course. The driver is  
headed toward trail waypoint 002, which is 5.65 miles away. Traveling  
at a speed of 70 mph, the driver will arrive at the waypoint in 3 min-  
utes, 24 seconds.  
The Navigation Page has its own menu, which is used for some ad-  
vanced functions and for setting various options. To access the Naviga-  
tion Page Menu, press MENU while on the Navigation Page.  
Map Page  
The Map Page screens show your course and track from a bird's-eye  
view. By default, this unit shows the map with north always at the top  
of the screen. (This can be changed. See the topic Map Orientation, in  
Sec. 8.) If you are navigating to a waypoint, the map shows your start-  
ing location, present position, course line and destination. You don't  
have to navigate to a waypoint to use the map.  
Map Page is the default screen that appears when you turn on the unit.  
To get to the Map Page from another page press PAGES|← → to  
MAP|EXIT. When the Map Page is displayed, a screen similar to the fol-  
lowing figures appears.  
The arrow in the center of the screen is your present position. It points  
in the direction you are traveling. The magenta line extending from the  
back of the arrow is your plot trail or path you've taken.  
The map zoom range is the distance across the screen. This number  
shows in the lower left corner of the screen. In the first of the following  
example figures, the range is 4,000 miles from the left edge of the map  
to the right edge of the map.  
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its  
coverage area and the amount of mapping detail shown. There are 40  
available map zoom ranges, from 0.02 miles to 4,000 miles.

Background map vs. MapCreate map content  
The background map includes, low-detail maps of the whole world (con-  
taining cities, major lakes, major rivers, political boundaries) and me-  
dium-detail maps of the United States.  
The medium-detail U.S. maps contain all incorporated cities, shaded  
metropolitan areas, county boundaries; shaded public lands (such as  
national forests and parks), some major city streets, Interstate, U.S.  
and state highways, Interstate highway exits and exit services informa-  
tion, large- and medium-sized lakes and streams and more than 60,000  
navigation aids and 10,000 wrecks and obstructions in U.S. coastal and  
Great Lakes waters  
MapCreate custom maps include massive amounts of information not  
found in the background map. MapCreate maps contain the searchable  
Points of Interest database, all the minor roads and streets, all the  
landmark features (summits, schools, radio towers, etc.) and smaller  
lakes, rivers, streams and ponds.  
What is more important is the large scale map detail that allows your  
GPS unit to show a higher level of position accuracy. For example, the  
background map would show you the general outline and approximate  
shape of a coastline or body of water, but the higher detail in MapCre-  
ate shows the shoreline completely and accurately. Many smaller is-  
lands would not be included in the background map, but are in Map-  
Create.

sory ordering information — FreedomMaps are pre-made maps that  
contain all of the same information available in a custom MapCre-  
ate map.

Café POI, which triggers a pop-up box with the POI name  
Tip:  
In some urban areas, businesses are so close to one another their  
POI icons crowd each other on the screen. You can reduce screen  
clutter and make streets and other map features easier to see by  
turning off the display of certain POIs. (To see how, check the text  
on Map Detail Category Selection, page 143. It shows how to use  
the Map Categories Drawn menu to turn individual POI displays  
off and on.) Even though they are not set for display, you can still  
search for POIs. The icons will pop-up when they are found.

Find Your Current Position  
Finding your current position is as simple as turning on the unit. Un-  
der clear sky conditions, the unit automatically searches for satellites  
and calculates its position in approximately one minute or less.  
NOTE:  
Clear sky conditions means open sky, unobstructed by terrain,  
dense foliage or structures. Clouds do not restrict GPS reception.  
If for some reason satellite acquisition takes longer, you may be inside  
a structure or vehicle or in terrain that is blocking signal reception. To  
correct this, be sure you are positioned so that the unit has as clear a  
view of the sky as possible, then turn the unit off and back on again.  
Moving Around the Map: Zoom & Cursor Arrow Keys  
The map is presented from a bird's eye view perspective. The current  
zoom range shows in the lower left corner of the screen.  
1. Press the ZIN key (zoom in) to move in closer and see greater detail in  
a smaller geographic area.  
2. Press the ZOUT key (zoom out) to move farther away and see less map  
detail, but a larger geographic area.  
When you are traveling, the map will automatically move as you move.  
This keeps your current location roughly centered on the screen.  
You can manually pan or scroll the map northward, southward, east-  
ward or westward by using the arrow keys, which launch the cross-hair  
map cursor. This allows you to look at map places other than your cur-  
rent position. To clear the cursor, press EXIT, which jumps the map  
back to the current position or the last known position.  
Tip:  
Use the cursor to determine the distance from your current position  
(or last known position, when working indoors) to any map object or  
location. Use the arrow keys to position the cursor over the object or  
place. The distance, measured in a straight line, appears in the  
popup data box. Press EXIT to clear the cursor.

Selecting Any Map Item With the Cursor  
1. Use the zoom keys and the arrow keys to move around the map and  
find the item you wish to select.  
2. Use the arrow keys and center the cursor cross-hair on the desired ob-  
ject. On most items, a pop-up box will give the name of the selected item.  
Tip:  
This unit has a Cursor Undo feature that lets you instantly return  
to the previous location without scrolling. Use the cursor to scroll  
across the map to some far away location or waypoint. Press EXIT to  
clear the cursor and jump back to your current position on the map.  
When you want to take another peek at that distant place, just  
press EXIT again. You can use this trick to toggle between your cur-  
rent position and your destination.  
Searching  
Now that you have seen how the unit can find your current location,  
let's search for something else. Searching is one of the most powerful  
features in the Eagle GPS product line.  
In this example, we will look for the nearest fast-food restaurant. For  
information on different types of searches, refer to Sec. 9, Searching.  
NOTE:  
This example requires the Point of Interest (POI) database included  
with a high-detail MapCreate 6 custom map.

not have a high-detailed custom map for the area you are searching, you  
may not find anything.  
Set a Waypoint  
A waypoint is an electronic address based on the latitude and longitude  
of a position on the earth. It represents a location, spot or destination  
that can be stored in memory, then recalled and used later on for navi-  
gation purposes.  
You can create a waypoint at the cursor position on the map or at your  
current position while navigating. You can create a waypoint at any  
location by manually entering the position's latitude and longitude. You  
can copy waypoints from your unit to your personal computer with  
MapCreate software. When you want to repeat a trip, these archived  
waypoints can be reloaded into your GPS unit.

easiest way to create a waypoint.  
Create Waypoint at Current Position  
While you are traveling, press WPT|WPT. The waypoint is saved and  
automatically given a name with a sequential number, such as way-  
point 003. The waypoint symbol and number appear on the map.  
NOTE:  
The Quick Save method uses the default waypoint symbol until you  
edit an existing waypoint and change its symbol. (Edit Waypoint  
Symbol is described in Sec. 7.) After you have changed a waypoint  
symbol, the unit will remember the one you chose and use it the  
next time you quick save a waypoint. To revert back to the default  
symbol, edit a waypoint and choose the original symbol, or use the  
Reset Options command (described in Sec. 8).

Set Man Overboard (MOB) Waypoint  
One of boating's most terrifying events is having a friend or family  
member fall overboard. This unit has a man overboard feature that  
shows navigation data to the location where the feature was activated.  
To activate it, press the ZOUT and ZIN keys at the same time. Your posi-  
tion at the time these keys are pressed is used as the man overboard  
position.  
Caution:  
Saving a new Man Overboard waypoint will overwrite and erase  
the previous Man Overboard waypoint.  
Navigate Back to MOB Waypoint  
Find your way back to the accident position with the Navigation Page  
or Map Page. When MOB is activated, the Navigation Page automati-  
cally shows the compass rose with its bearing arrow pointing toward  
the man overboard position, and the destination name says Going To  
Man Overboard. The Map Page displays a Man Overboard waypoint,  
represented by a human figure, and the steering arrow points where to  
steer to reach that position.  
Navigating to Man Overboard: Man Overboard activated message  
(left). The Navigation Page is shown (center). Going to Man Overboard  
position on Map Page (right).  
The man overboard position is also stored in the waypoint list for future  
reference. It can be edited the same as any other waypoint. This pre-  
vents the inadvertent loss of the current Man Overboard position.  
To cancel navigation to MOB, press MENU|MENU|to CANCEL NAVIGA-  
TION|ENT|to YES|ENT. The unit stops showing navigation information.

Navigate to Cursor Position on Map  
The GO TO CURSOR command navigates to the current cursor position on  
the map. It is a quick way to navigate to anything you can see on the  
map display.  
1. Use the cursor with the zoom in and zoom out keys to move around  
the map until you find a location you want to go to.  
2. Center the cursor over the location to select it. See the example in  
the following figure. Map items like waypoints, Points of Interest and  
towns among others, can be selected and appear highlighted with a  
pop-up box. Other features, such as a river or a street intersection will  
not appear highlighted, but the cursor will take you to those locations  
just the same.  
The cursor crosshairs are centered on Oologah, Oklahoma.  
3. Press MENU|ENT and the unit will begin navigating to the cursor lo-  
cation.  
The Map Page will display a red line from your current position to the cur-  
sor position. The Navigation Page displays a compass rose showing naviga-  
tion information to your destination. See the following examples.  
107  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The 60-mile zoom figure (left) shows the red course line connecting the  
current position to the destination. The Navigation Page (right) will also  
show navigation information.  
To stop navigating to the cursor, use the Cancel Navigation command.  
Press MENU|MENU|to CANCEL NAVIGATION|ENT|to YES|ENT. The unit  
stops showing navigation information.  
Navigate to a Point of Interest  
You can use the Navigate to Cursor command for POIs in view on the  
map, just use the cursor to select the POI.  
The other method involves searching for POIs with the Find Waypoint  
command, launched with the WPT key. (See the searching example ear-  
lier in this section or turn to Sec. 9, Searching, for more instructions.)  
After you have looked up an item with the Find Waypoint command,  
use ← → to make sure the GO TO command is highlighted at the bottom  
of the screen, then press ENT. The unit begins showing navigation in-  
formation to the item.  
To cancel navigation, press MENU|MENU|to CANCEL NAVIGATION|ENT|←  
to YES|ENT. The unit stops showing navigation information.  
Creating and Saving a Trail  
A trail or plot trail, is a string of position points plotted by the unit as you  
travel. It is a travel history, a record of the path you have taken. Trails  
are useful for repeating a journey along the same track. They are par-  
ticularly handy when you are trying to retrace your trip and go back the  
way you came. On the screen, trails are represented by a solid line ex-  
tending from the back of the current position arrow. The default color is  
light magenta.  
108  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The unit is set to automatically create and record a trail when it is  
turned on. The unit will continue recording the trail until the length  
reaches the maximum trail point setting. The default is 2,000 points,  
but the unit can record trails 9,999 points long. When the point limit is  
reached, the unit begins recording the trail over itself.  
With the default auto setting, this unit creates a trail by placing a dot on  
the screen every time you change directions. The methods used for creat-  
ing a trail and the trail update rate can be adjusted or even turned off.  
See Sec. 8 for Trail Options.  
To preserve a trail from point A to point B, you must turn off the trail  
by making it inactive before heading to point C or even back to point A.  
When the current trail is set inactive, the unit automatically begins  
recording a new trail.

repeatedly. Repeat the steps above to the turn on the trail display.  
Navigating Trails  
There are three methods for following a trail: visual trailing, navigating  
a trail and backtracking a trail. Try each method to see which you pre-  
fer.  
Visual trailing is the simplest method. It uses only the Map Page and  
requires no menu commands at all. The technique works the same if  
you are running a trail forward (from start to end) or backward (from  
end to start.) Visual trailing, however, provides no navigation informa-  
tion during the trip, like time to your destination.  
The other two methods provide a full range of navigation data and work  
with both the Map Page and Navigation Page. The only difference be-  
tween them is navigating a trail follows a trail forward while back-  
tracking follows a trail in reverse.  
When hiking at walking speed with a hand-held GPS, we often just use  
visual back trailing because it is a bit better at following each turn on a  
foot path. At faster speeds, like on the highway or on the water, the  
Navigate Trail and Backtrack Trail commands are handy.

Visual Trailing  
1. On the Map Page, zoom (ZIN or ZOUT) so your trail is visible.  
2. Begin moving and watch the Map Page. Walk or steer so your cur-  
rent position arrow traces along the trail you have just made.  
Tip:  
Generally, when using this method, the smaller the zoom range, the  
more accurately you will be able to steer along the trail.

Icons  
Icons are graphic symbols used to mark some location, personal point of  
interest or event. They can be placed on the map screen, saved and re-  
called later for navigation purposes. These are sometimes referred to as  
event marker icons. This unit has 42 different symbols to choose from  
when creating an icon.  
Icons are similar to waypoints, but they do not store as much informa-  
tion (like names) as waypoints do. You can not use a menu to navigate  
to icons as you can with waypoints. But, you can use the map cursor  
and navigate to any icon on the map.  
You can create an icon at the cursor position on the map or at your cur-  
rent position while navigating.

Routes  
A route is a series of waypoints, linked together in an ordered sequence  
used to mark a course of travel. You can visualize a route as a string of  
beads. The beads represent waypoints and the string represents the  
course of travel connecting waypoint to waypoint. The course from one  
waypoint to the next is a leg. Routes are composed of one or more legs.  
The legs of all GPS routes are based on straight lines between way-  
points.  
119  
Download from Www.Somanuals.com. All Manuals Search And Download.  
A route allows you to navigate through several waypoints without  
having to reprogram the unit after arriving at each waypoint. Once  
programmed into the GPS unit, a route provides the option of navigat-  
ing forward through the route waypoints or in reverse order. You can  
even begin navigating in the middle of a route.  
Create and Save a Route  
You have the option of creating and editing a route in the unit or you  
can make a route on your computer with our MapCreate 6 software.  
PC-created Routes  
MapCreate is the easiest method for preparing a route, because your  
PC's larger screen, keyboard and mouse are easier to manipulate than  
the unit.  
To load a MapCreate route into the unit, follow instructions in MapCre-  
ate's manual for creating a route and saving it as part of a GPS Data File  
(file format *.usr). Copy the GPS Data File to an MMC and insert the  
MMC in the unit. (See Sec. 2 for instructions on installing MMCs. To  
load the GPS Data File into the unit's memory, see the entry on Transfer  
Custom Maps & GPS Data Files in Sec. 6, Basic GPS Operations.)  
Routes Created in the Unit  
You can create a route by selecting existing waypoints from the way-  
point list or you can set a series of route waypoints on the map with  
cursor arrows and the Enter key. In this example, we will create a  
route from the map.

Section 8: System & GPS Setup  
Alarms  
This unit has three GPS alarms: Arrival Alarm, Off Course Alarm and  
Anchor Alarm — the only one of the three set to Off by default.  
You can set an arrival alarm to flash a warning message and sound a  
tone when you cross a preset distance from a waypoint. For example, if  
you have the arrival alarm set to .1 mile, the alarm will flash a mes-  
sage when you come within .1 mile of your destination.  
The off course alarm warns you when your track drifts too far to the  
right or left of the course line to your destination. For example, if the  
alarm is set to .1 mile, then the alarm flashes a message if you drift .1  
miles or more to the right or left of the course line.  
The anchor alarm is triggered when you drift outside of a preset radius.  
If you are anchored and your boat moves more than .1 miles, the alarm  
will flash a message and sound a tone.

use when displaying and entering position coordinates.  
Menus used for changing coordinate system.  
To get to Coordinate System Selection:  
1. Press MENU|MENU|to GPS SETUP|ENT.  
2. Press to COORDINATE SYSTEM|ENT.  
This unit can show a position in degrees (36.14952°); degrees, minutes  
and thousandths of a minute (36° 28.700'); or degrees, minutes, seconds  
and tenths of a second (36° 28' 40.9"). It can also show position in: UTM  
(Universal Transverse Mercator) projection; MGRS (Standard); MGRS  
(Standard + 10); Map Fix; Loran TD; British, Irish, Finnish, German,  
New Zealand, Swedish, Swiss, Taiwan and Greek grid systems.  
UTM's are marked on USGS topographic charts. This system divides  
the Earth into 60 zones, each 6 degrees wide in longitude.  
British, Irish, Finnish, German, New Zealand, Swedish, Swiss, Taiwan,  
and Greek grid systems are the national coordinate system used only in  
their respective countries. In order to use these grid systems, you must  
be in the respective country. This unit will pick the matching datum for  
you when you select the grid. See the entry on Map Datum Selection for  
more information.

Download from Www.Somanuals.com. All Manuals Search And Download.  
The Military Grid Reference System (MGRS) uses two grid lettering  
schemes, referred to as standard and standard + 10 MGRS on this unit.  
Your position and datum in use determines which one to use. If you use  
standard and your position is off significantly, then try the alternate.  
NOTE:  
When the position format is changed, it affects the way all positions  
are shown on all screens, including waypoints.  
To change the coordinate system, press ENT while COORDINATE SYSTEM is  
highlighted. Use ↑ ↓ to highlight the desired format. Press ENT to select  
it.  
To setup Loran TD:  
NOTE:

ran chain identification for the master and slaves. Do this by se-  
lecting Setup Loran TD at the bottom of the Coordinate System  
menu, then selecting the desired ID. Press EXIT to close this menu.  
Configure Loran TD menu.  
Map Fix  
Map Fix is used with charts or maps. This system asks for a reference  
position in latitude/longitude, which you take from a marked location  
on the map. It then shows the present position as distance on the map  
from that reference point.  
For example, if it shows a distance of UP 4.00" and LEFT 0.50", you  
then measure up four inches and to the left a half-inch from the refer-  
ence point on the map to find your location.

To configure a map fix:  
To use this format, you need to follow these steps in order. Take a map  
of the area and determine a reference latitude/longitude.  
NOTE:  
In order for this system to work, the latitude/longitude lines must  
be parallel with the edge of the map. USGS maps are parallel, oth-  
ers may not be. Also, this works better with smaller scale maps,  
such as 1:24000.  
The reference position can be anywhere on the map, but the closer it is  
to your location, the smaller the numbers you will be working with.  
Once you have decided on a reference position, you can save it as a way-  
point. See the waypoint section for information on saving a waypoint.  
Save the reference position as a waypoint. Exit the waypoint screens.

Map Overlays (Range Rings; Lat/Long Grid)  
The map screen can be customized with four range rings and/or grids  
that divide the map into equal segments of latitude and longitude.  
Range rings are handy for visually estimating distances on the map. The  
ring diameters are based on the current zoom range. At a 100-mile zoom,  
the screen will show two rings with your current position in the center.  
The large ring touching the left and right sides of the screen is 100 miles  
in diameter (same as the zoom range). The second smaller ring is 50  
miles in diameter (always 1/2 the zoom range).  
The distance from your current position to the smaller ring (the ring's  
radius) is 25 miles (always 1/4 the zoom range). With the map cursor,  
you can scroll over to see the third and fourth rings. In this example,  
the distance to the third ring is 75 miles and distance to the fourth ring  
is 100 miles from your current position.

Map orientation shown in north up (left) and track up (right).  
This is fine if you are always traveling north. What you see to your left  
and right corresponds with the left and ride sides of the map. But if you  
travel any other direction, the map does not line up with your view.

To correct this problem track-up mode rotates the map as you turn. So  
what you see on the left side of the screen should always be to your left  
and so on.  
Another option is course-up mode, which keeps the map at the same  
orientation as the initial bearing to the waypoint. When either track-up  
or course-up modes are on, an "N" shows on the map screen to keep you  
aware of which direction is north.

Shipping Information  
If it becomes necessary to send a product for repair or replacement, you  
must first receive a return authorization number from Customer  
Service. Products shipped without a return authorization will not be  
accepted. When shipping, we recommend you do the following:  
1. Please do not ship the knobs or mounting bracket with your unit.  
2. If you are sending a check for repair, please place your check in an  
envelope and tape it to the unit.  
3. For proper testing, include a brief note with the product describing  
the problem. Be sure to include your name, return shipping address  
and a daytime telephone number. An e-mail address is optional but  
useful.  
4. Pack the unit in a suitable size box with packing material to prevent  
any damage during shipping.  
5. Write the Return Authorization (RA) number on the outside of the  
box underneath your return address.  
6. For your security, you may want to insure the package through your  
shipping courier. Eagle does not assume responsibility for goods lost or  
damaged in transit.
