Introduction  
Thank you for buying a Lowrancesonar! Your unit is a high-quality  
sonar designed for both professional and novice fishermen. All  
Lowrance sonars have an automatic mode that finds and displays the  
bottom, fish, underwater structure and more – right out of the box. All  
you have to do is press the on (PWR) key.  
However, if you want to fine-tune your unit, press the MENU UP key.  
The X51 and X58DF have several powerful features you can control by  
scrolling through easy-to-use menus with the arrow and menu keys.  
To get started with your Lowrance sonar, first read the installation sec-  
tion. It contains instructions for mounting the sonar unit, the trans-  
ducer and any optional accessories, such as a speed sensor.  
Following recommended installation practices will pay off in optimum  
performance of your Lowrance sonar. Improper installation can cause  
problems down the road, especially if the transducer is badly mounted.  
After you've read the installation instructions, install the unit and ac-  
cessories. Then, read the rest of the manual. The more you know about  
your sonar, the better it will work for you.  
Take advantage of the Simulator feature. It allows you to practice oper-  
ating your sonar before you get it in the water. And when you finally  
head for your favorite fishing hole, take this manual along for reference.

storage in temperatures higher or lower than specified will damage  
the liquid crystal display in your unit. This type of damage is not  
covered by the warranty. For more information, contact the fac-  
tory's Customer Service Department; phone numbers are inside the  
manual's back cover.  
Transducer Installation  
These instructions will help you install your Skimmertransducer on a  
transom, on a trolling motor or inside a hull. These instructions cover  
2

both single- and dual-frequency Skimmer transducers. Please read all  
instructions before proceeding with any installation.  
The smaller single-frequency Skimmers typically use a one-piece,  
stainless steel mounting bracket. The larger dual-frequency Skimmers  
typically use a two-piece, plastic mounting bracket. The trolling motor  
mount uses a one-piece plastic bracket with an adjustable strap.  
These are all "kick-up" mounting brackets. They help prevent damage if  
the transducer strikes an object while the boat is moving. If the trans-  
ducer does "kick-up," the bracket can easily be pushed back into place  
without tools.  
Read these instructions carefully before attempting the installation.  
Determine which of the mounting positions is right for your boat. Use  
extreme care if mounting the transducer inside the hull, because once it  
is epoxied into position, the transducer usually cannot be removed.  
Remember, the transducer installation is the most critical part  
of a sonar installation.  
Recommended Tools and supplies  
If you prefer the option of routing the cable through the transom, you  
will need a 1" drill bit. A transom mount requires use of a high quality,  
marine grade above- or below-waterline caulking compound. The fol-  
lowing installation types also call for these recommended tools and re-  
quired supplies (supplies 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. Supplies: 100 grit sandpaper, good quality  
epoxy adhesive.  
Selecting a Transducer Location  
1. The transducer must be placed in a location that has a smooth flow of  
water at all times. If the transducer is to be mounted inside the hull,  
3
Download from Www.Somanuals.com. All Manuals Search And Download.  
then the chosen location must be in the 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 location on alumi-  
num boats is between the ribs closest to the engine.  
2. The transducer should be installed with its face pointing straight  
down, if possible.  
3. 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.  
4. 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  
transducer 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.

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 protec-  
tion from bangs and bumps.

centerline  
Hull bottom  
Align transducer centerline with hull bottom.  
However, there 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 fre-  
quently lose bottom signal lock while running at high speed, the trans-  
ducer 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  
Typically, shoot-thru-hull installations give excellent high speed opera-  
tion and good to excellent depth capability. There is no possibility of  
damage from floating objects. It can't be knocked off when docking or  
loading on the trailer.  
However, 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. This can be a problem on some hulls that sit with the bow high  
when at rest or at slow trolling speeds. Follow the procedure listed in  
the shoot-thru-hull installation section at the end of this lesson to de-  
termine 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 plas-  
tic bracket and two on either side of the transducer as shown in the fol-  
lowing illustrations. Notice there are letters molded into each ratchet.  
Place the ratchets into the bracket with the letter "A" aligned with the  
alignment mark molded into the bracket. Place the ratchets onto the  
transducer with the letter "A" aligned with the 12 o'clock position on  
the transducer stem. These positions set the transducer's coarse angle  
adjustment for a 14° transom. Most outboard and stern-drive tran-  
soms 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  
parallel 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.

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  
parallel 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.

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 at left and seen from above at 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 caulking compound.  
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 cau-  
tion 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 be 1".  
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 trans-  
ducer bracket down. This puts the transducer deeper into the water,  
hopefully 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.)

2. Slide the adjustable strap supplied with the TMB-S through the slot  
in the transducer bracket and wrap it around the trolling motor. Po-  
sition the transducer to aim straight down when the motor is in the  
water. 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 troll-  
ing 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 trans-  
ducer 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.

Transducer angles and their effects on fish arches.  
If the arch slopes up – but not back down – then the front of the trans-  
ducer 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  
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  
12  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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.  
Fill with epoxy  
Inner hull  
Flotation material  
Epoxy to hull first  
Outer hull  
Epoxy the transducer to a solid portion of the hull.  
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 di-  
rectly to the outer layer of fiberglass. After the epoxy cures, 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.  
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.  
To choose the proper location for thru-hull mounting, anchor the boat in  
60 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. Adjust the sensitivity and range controls until a sec-  
ond bottom echo is seen on the display. (You will need to turn off both  
automatic and ASP.) Don't touch the controls once they've been set.  
Next, take the transducer out of the water and place it in the water in  
the sump of the boat. Observe the sonar signal to see if there is a no-  
ticeable decrease in sensitivity. The second bottom signal may disap-  
pear and the bottom signal may decrease in intensity.  
Move the transducer around to find the best location. If the sensitivity  
control must be increased greatly to compensate, then the transducer  
should be mounted on the outside of the hull. If not, then mark the lo-

Shoot-thru-hull Installation  
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 surface of the hull must be flat so the entire  
transducer face is in contact with the hull prior to bonding.  
Spread epoxy here  
Sand this surface  
Epoxy transducer to hull.  
2. Follow the instructions on the epoxy package and mix it thoroughly.  
Do not mix it too fast, because it will cause bubbles to form in the ep-  
oxy. Apply a small amount on the face of the transducer as shown  
above, then spread a small amount onto the sanded area on the hull.  
14

Place the transducer into the epoxy, twisting and turning it to force  
any air bubbles out from under the transducer face. The face of the  
transducer should be parallel with the hull, with a minimum amount  
of epoxy between the hull and transducer. After the epoxy dries,  
route the cable to the sonar unit.  
Speed/Temperature Sensors  
The X51 and X58DF 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.  
The X58DF is packed with a speed sensor and a transducer containing  
a built-in temp sensor. If you want a second temp reading, you will  
need either an external temp sensor or a combination speed/temp sen-  
sor. See the Accessory Ordering Information in the back of this manual.  
If a second temp sensor is used, it must be the model TS-2X. 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 temperature  
sensor.

purchase an optional additional sensor for your unit, refer to the acces-  
sory 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, 7/8" 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 caulking compound.  
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. Also make sure the location doesn't inter-  
fere with the boat's trailer. Typically, the sensor is mounted about one foot  
to the side of the transom's centerline.  
Once you've determined the proper location for the unit, place the sen-  
sor 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  
screws' 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  
caulking compound to seal the screws. Make sure the sensor is flush  
with the bottom of the hull and tighten the screws.

If the base of the transom has a radius, fill the gap between the tran-  
som and the sensor with the caulking compound. This will help ensure  
a smooth water flow.  
Route the sensor's cable through or over the transom to the sonar unit.  
If you need to drill a hole in the transom to pass the connector through,  
the required hole size is 7/8".  
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 in-line con-  
nector on the MY-4X adapter cable. If you have any questions concern-  
ing 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.

battery  
Power connections for the X51 and X58DF sonar 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.  
CAUTION:  
Do not use this product without a 3-amp fuse wired into the  
power cable! Failure to use a 3-amp fuse will void your warranty.  
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.  
MOUNTING THE SONAR UNIT: In-Dash, Bracket or Portable  
You can install the sonar unit on the top of a dash with the supplied  
bracket. It can also be installed in the dash with an optional FM-4  
mounting kit.  
If you use the supplied gimbal bracket, you may be interested in the  
optional GBSA-1 swivel bracket kit. This converts the unit's gimbal  
bracket to a swivel mount which can be used on the dash or overhead  
mounting positions. Installation instructions for the in-dash and swivel  
mounting kits are supplied with the adapter kits.  
In-Dash Installation  
The following figure shows dimensions for in-dash mounting. The in-  
dash adapter kit includes a template for cutting the mounting hole and  
complete installation directions on instruction sheet 988-0147-44.

Bracket Installation  
Mount the unit in any convenient location, provided there is clearance  
when it’s tilted for the best viewing angle. Holes in the bracket’s base  
allow wood screw or through-bolt mounting. It may be necessary to  
place a piece of plywood on the back side of thin panels to reinforce the  
panel. Make certain there is enough room behind the unit to attach the  
power and transducer cables.  
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, however, prefer to mount the bracket to the side of the  
cable hole — it's a matter of personal preference.  
After drilling the hole, pass the transducer connector up through the  
hole from under the dash. Drop the power cable's bare-wire end down  
though the hole from the top.

If you wish, you can fill in the hole around the cables with a good ma-  
rine caulking compound. (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, thus 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. Slide the rubber washers onto the gimbal knobs then  
loosely screw the knobs into their sockets. Slide the unit into the  
bracket with the rubber washers to the outside of the bracket arms. Tilt  
the unit to the desired viewing angle and tighten the knobs finger tight  
Portable Sonar Installation  
Like many Lowrance products, the X51 and X58DF sonars are capable  
of portable operation by using the optional PPP-10 portable power pack.  
The power pack and portable or floating transducers expand the uses

for your sonar. You can use your X51 or X58DF 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.  
The PPP-10 Portable Power Pack can be used with eight "D" cell alkaline  
batteries (not included) or an optional sealed, rechargeable battery. For  
set-up directions, refer to the pack's instruction sheet, part 988-0147-45.

RANGE  
When turned on for the first time, the unit automatically adjusts the  
depth range according to water conditions. It always keeps the bottom  
displayed in the lower portion of the screen. You can over-ride the  
automatic range control and manually select a range.  
To do this, press MENU until the RANGE menu appears. Use the arrow  
keys to select the desired range. When you're finished, press PWR to  
clear the menu from the display.

This unit has the following ranges:  
10, 15, 20, 30, 40, 60, 80, 100, 150, 200, 300, 500, 800 and 1,000 feet.  
RANGE - Upper and Lower Limits  
In addition to the unit's Zoom command, which enlarges all the echoes  
on the screen, you can "zoom in" on just a portion of the water column  
by using the Upper and Lower Limits feature on the Range menu.  
The upper and lower limits you set must be separated by a minimum of  
10 feet. This range limit feature will not work when the Range feature  
is in auto mode.

NOTE:  
Using the Zoom command while in auto Range mode will always  
enlarge the echoes near the bottom, because auto Range always  
keeps the bottom displayed in the lower portion of the screen.  
When you Zoom in manual Range mode, echoes are enlarged near  
the middle of the displayed range. For example, with a manual  
depth Range of 100 feet, your screen shows the water column from  
zero at the top of the screen to 50 feet in the middle to 100 feet at  
the bottom of the screen. Select 2X Zoom and the screen will show  
the water column from zero to 50 feet, with 25 feet shown in the  
middle of the screen. Select 4X Zoom and the screen shows the wa-  
ter column from 13 feet to about 39 feet, with 25 feet still in the  
middle of the screen.  
Important Tip:  
Your unit has the handy ability to quickly zoom in on any portion of  
the water column with just the touch of an arrow key. The Zoom  
Pan feature lets you rapidly move the zoomed area up and down to  
different depths. By "pointing" your zoom at different portions of  
the chart as it scrolls, you can get a good, close-up look at structure  
or cover below you.  
To use Zoom Pan, switch to a manual depth Range setting (see page  
33) and turn on 2X or 4X Zoom. Then, simply press the UP ARROW  
or DOWN ARROW to pan up and down the water column.

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 situations when too much clutter appears on the screen. Decreasing  
the sensitivity can reduce the clutter and show the strongest fish ech-  
oes, if fish are present. As you change the sensitivity setting, you can  
see the difference on the chart as it scrolls.

These figures show results of different sensitivity levels on the same

ity. Typical of full auto mode. Fig. 2: Sensitivity set at 50 percent. Fig.  
3: Sensitivity set at 20 percent. Fig. 4: Sensitivity set at 100 percent.  
You can change the sensitivity level whether you are in Auto Sensitiv-  
ity mode or Manual Sensitivity mode. The adjustment method works  
the same in both modes, but it gives you slightly different results.  
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 your unit, auto mode will let you increase sensitivity to  
100 percent, but the unit will limit your minimum setting. This prevents  
33  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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 sensi-  
tivity 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 your unit, manual mode allows you to set sensitivity at  
100 percent (maximum) or zero percent (minimum.) Depending on wa-  
ter and bottom conditions, the bottom signal may completely disappear  
from the screen when you reduce sensitivity to about 20 percent or less!  
Try adjusting sensitivity in both auto and manual modes to see how  
they work.

adjusting sensitivity in auto mode above.  
GRAYLINE®  
Graylinelets you distinguish between strong and weak echoes. It  
"paints" gray on targets that are stronger than a preset value. This al-  
lows you to tell the difference between a hard and soft bottom. For ex-  
ample, a soft, muddy or weedy bottom returns a weaker signal which is  
shown with a narrow or no gray line. A hard bottom returns a strong  
signal which causes a wide gray line.  
If you have two signals of equal size, one with gray and the other with-  
out, then the target with gray is the stronger signal. This helps distin-  
guish weeds from trees on the bottom, or fish from structure.  
Grayline is adjustable. The factory default for this unit is 69 percent.  
Since Grayline shows the difference between strong and weak signals,  
adjusting the sensitivity may also require a different Grayline level.  
The level chosen by the sonar unit at power on is usually adequate for  
most conditions. Experiment with your unit to find the Grayline setting  
that's best for you.  
To change the Grayline level, press MENU until the GRAYLINE menu appears.

change. If you reach the maximum or minimum level, a tone sounds  
alerting you to the limits. Press PWR to clear the menu.  
FISH I.D.  
The Fish I.D.feature identifies targets that meet certain conditions  
as fish. The microcomputer analyses all echoes and eliminates surface  
clutter, thermoclines and other signals that are undesirable. In most  
instances, remaining targets are fish.  
The Fish I.D. feature displays symbols on the screen in place of the ac-  
tual fish echoes. There are three symbol sizes: small, medium, and  
large. These show the relative size between targets. In other words, it  
displays a small fish symbol when it thinks a target is a small fish, a  
medium fish symbol on a larger target and so forth.

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 microcomputer is sophisticated, but it can be fooled.  
It can't distinguish between fish and other suspended objects such as  
trotlines, turtles, submerged floats, air bubbles, etc. Individual tree  
limbs extending outward from a group of limbs are the hardest objects  
for the Fish I.D. feature to distinguish from fish.  
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.

You may see Fish I.D. symbols on the screen when actually, there are no fish.  
The reverse is also true — Fish I.D. can actually miss fish that are present.  
Does that mean Fish I.D. is broken? No — the feature is simply inter-  
preting sonar returns in a specific way to help take some of the work  
out of reading 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 information. 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 familiar with the feature. The default for Fish I.D. is off.  
Fish I.D. is most handy when you're 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'll hear it!  
Fish I.D. can also be useful when you want to screen out some of the so-  
nar detail gathered by your unit. For example, it can help cut through  
the clutter of suspended bubbles caused by wave action or boat wakes.  
To turn Fish I.D. on, press MENU until the FISH ID menu appears. Press  
UP ARROW to select ON, then press PWR. To turn it back off, repeat the  
above steps, but press DOWN ARROW to select OFF.  
FISHTRACK™  
The FishTrackfeature shows the depth of a fish symbol when it ap-  
pears on the display. To turn it on, press MENU until the FISH ID menu  
appears. Press UP ARROW to select TRACK ON, then press PWR. To turn it  
off, repeat the above steps, but press DOWN ARROW to select OFF. (If you  
want to turn off FishTrack depths but leave Fish I.D. on, press DOWN  
ARROW to select ON, then press PWR.) Remember, Fish I.D. must be on  
in order to use the FishTrack feature.

FISHREVEAL  
When displaying actual sonar returns, the FishRevealfeature helps  
show fish targets hidden by surface clutter, thermoclines, weed beds  
and other cover with 10 levels of gray tones.  
Normal operation (with FishReveal turned off) shows the weakest ech-  
oes as black and the strongest in light gray. Since all weak echoes are  
black, fish arches show boldly against the white background. The  
drawback is that all weak echoes — such as thermoclines — are also  
accentuated. This can make it hard to distinguish fish signals inside  
thermoclines or other cover.  
At left FishReveal menu screen. The feature is off and screen is in  
normal mode. Right, Fish Reveal is on, in standard mode.  
There are two FishReveal modes: standard and inverted. In standard  
mode, the weakest echoes are white and the strongest echoes are black.  
Echoes in between vary in gray in proportion to their signal strength.  
In Inverted FishReveal mode, the weakest echoes are black and the  
strongest echoes are white. Again, echoes in between vary in gray in  
proportion to their signal strength. In all modes, the Grayline control  
determines the range for black to white.  
To turn FishReveal on, press MENU DOWN until CHART SETUP appears,  
then press UP ARROW. Press MENU DOWN until CHART MODE appears.

CHART SCROLL SPEED and HYPERSCROLL  
The rate that echoes scroll across the screen is called the chart scroll  
speed. The default for this unit is 60 percent; we recommend that you  
leave the scroll speed set there for virtually all fishing conditions.  
However, you might consider experimenting with chart speed when you  
are stationary or drifting very slowly. You may sometimes achieve bet-  
ter images as you slow down the chart speed to match how fast you are  
moving across the bottom.  
Switching to a scroll speed faster than 60 percent can be helpful when  
running at high speed. Any setting greater than 60 switches the unit to  
HyperScroll. This feature scrolls the echoes at an extremely high rate  
of speed, giving you the maximum screen update.  
If you are at anchor, ice fishing or fishing from a dock, experiment with  
a chart speed of 20 percent. If you are drifting slowly, try a chart speed  
of 40 percent. When you are stationary and a fish swims through the  
sonar signal cone, the image appears on the screen as a long line in-  
stead of a fish arch. Reducing the chart speed may result in a shorter  
line that more closely resembles a regular fish return.

At right, Scroll Speed menu at default 60 percent setting. At left, Scroll  
Speed menu, with unit set to HyperScroll mode.  
If you are running fast, try a HyperScroll setting of 80 to 100 percent.  
When using HyperScroll, you may also need to manually decrease the  
sensitivity for best performance. Depending on water conditions, Hy-  
perScroll may cause a second bottom echo and large amounts of clutter  
to appear on the screen. If this occurs, just decrease the sensitivity to a  
level that eliminates the clutter. When you turn HyperScroll off, you  
can return to your original sensitivity level.  
Adjust scroll speed by pressing MENU until SCROLL SPEED appears. Press  
UP ARROW to increase it and press DOWN ARROW to decrease it. Press  
PWR to clear the menu.  
To return to the original setting, repeat the above steps, but use the  
arrow keys to set the speed at 60 percent before clearing the menu.  
NOISE REJECT and ASP(Advanced Signal Processing)  
The ASP(Advanced Signal Processing) feature is a noise rejection  
system built into the sonar unit. It constantly evaluates the effects of  
boat speed, water conditions and electrical interference and automati-  
cally gives you the best display possible under most conditions.  
ASP 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.

Download from Www.Somanuals.com. All Manuals Search And Download.  
The ASP noise rejection feature is especially useful because it typically  
lets you operate the boat at all speeds without adjusting the sensitivity  
or other controls.  
Noise Reject menu.  
The ASP feature has four settings — Off, Low, Medium and High.  
When first turned on, noise rejection is set on low. If you have high  
noise levels, try using the medium or 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 ASP off. This allows you to  
view all incoming echoes before they are processed by the ASP feature.  
To change the ASP setting, press MENU DOWN until NOISE REJECT ap-  
pears. Use the up and down arrow keys to select the desired setting,  
then press PWR to clear the menu.  
ALARMS  
The sonar unit has two different types of alarms, fish and depth.  
Fish Alarm  
The Fish Alarm sounds a tone when a fish symbol appears on the  
screen. The default setting is on, but the Fish I.D. feature must be  
turned on for fish alarms to work.  
To turn Fish I.D. on, press MENU until the FISH ID menu appears. Press  
UP ARROW to select ON, then press PWR.

Depth Alarms  
The depth alarms are triggered only by the bottom signal. No other  
echoes will activate these alarms. The depth alarms consist of a shallow  
and a deep alarm. The shallow alarm sounds an alarm tone when the  
bottom goes shallower than the alarm's setting. The deep alarm sounds  
a tone when the bottom goes deeper than its setting. Both alarms ad-  
just the same way, although through different menus.  
Shallow Alarm  
To set the shallow alarm depth, press MENU DOWN repeatedly until

NOTE:  
If you turn on your unit before attaching a transducer, it may enter  
a demo mode. The words "demo mode" flash on the bottom of the  
screen and a sonar chart plays much like the simulator. Unlike the  
simulator, the demo mode is for demonstration only, and will auto-  
matically stop as soon as you turn on the unit with a transducer at-  
tached. The simulator will continue to function normally.  
CHART SETUP  
The Chart Setup menu lets you further customize the display. The size  
of the digital numbers for the depth, temperature, speed and distance  
log can be customized from this menu. The depth scales shown on the  
right side of the screen can be modified, and the Fish Reveal modes can  
be turned on or off.

LIMIT SEARCH  
The Limit Search command helps you maintain maximum chart detail  
when you are moving fast in deep water (about 200 feet.) When turned  
on, Limit Search prevents the digital sonar from over-riding the sonar  
chart's depth range setting.  
Limit Search does this by preventing the digital sonar from slowing  
down the ping speed as it automatically searches for and tracks the bot-  
tom. The default setting is off, and this should fit most freshwater  
fishing situations.  
49  
Download from Www.Somanuals.com. All Manuals Search And Download.  
High boat speed and slow ping speed (caused by the deeper bottom) can  
reduce the screen refresh rate. This in turn can reduce the amount of  
detail seen on the sonar chart. Try this command only if you are in deep  
water, traveling at high speed, and notice a reduction in detail on the  
sonar chart. When Limit Search is turned on, the digital sonar will  
limit its search for the bottom to the depth range you have set for the  
sonar chart.  
NOTE:  
Turning Limit Search on can cause the digital sonar to lose the bot-  
tom in some situations. The digital depth will flash if that occurs.  
The sonar chart must be in manual depth range mode to use the Limit  
Search command. To switch from auto depth range to manual, press  
MENU until the RANGE menu appears. Use the arrow keys to select the  
desired range. When you're finished, press PWR to clear the menu from  
the display.

FREQUENCY (Change Transducer Frequency)  
(X58DF only)  
The X58DF 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.  
50  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The default frequency is 200 kHz, which is 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 very deep salt water, 300 to 500 feet or deeper, the 50 kHz fre-  
quency is the best choice.  
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 of thumb. Some fishermen  
on freshwater lakes (or the ocean) using downriggers like to see them  
on the sonar. In many of those cases, you'll see a 50 kHz transducer  
frequency in use because the wider cone angle lets them watch the bait.

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 certain the power cable is wired properly. The red wire con-  
nects 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 11 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 operates only in demo mode:  
1. The transducer has not yet been connected or has been disconnected.  
To leave demo mode, make sure the transducer is securely connected  
before turning the unit on.  
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 both the transducer and power connectors. Make certain both  
are securely plugged in to the unit.  
Weak bottom echo, digital readings erratic, or no fish signals:  
1. Make certain the transducer is pointing straight down. Clean the  
face of the transducer. Oil, dirt and fuel can cause a film to form on the  
transducer, reducing its effectiveness. If the transducer is mounted in-  
side the hull, be sure it is shooting through only one layer of fiberglass  
and that it is securely bonded to the hull. Do NOT use RTV silicone  
rubber adhesive or Marine-Texepoxy.  
2. Electrical noise from the boat's motor can interfere with the sonar.  
This causes the sonar to automatically increase its Discrimination or  
53  
Download from Www.Somanuals.com. All Manuals Search And Download.  
noise rejection feature. This can cause the unit to eliminate weaker  
signals such as fish or even structure from the display.  
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 certain 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.  
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 certain 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 certain 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 certain to use the in-line fuse  
supplied 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 for the best mounting position.
