How Sonar Works  
Sonar technology is based on sound waves. The 500 Series™ Fishfinder uses  
sonar to locate and define structure, bottom contour and composition, as well  
as depth directly below the transducer.  
Your 500 Series™ Fishfinder sends a sound wave signal and determines  
distance by measuring the time between the transmission of the sound wave  
and when the sound wave is reflected off of an object; it then uses the reflected  
signal to interpret location, size, and composition of an object.  
Sonar is very fast. A sound wave can travel from the surface to a depth of  
240 ft (70 m) and back again in less than 1/4 of a second. It is unlikely that your  
boat can “outrun“ this sonar signal.  
SONAR is an acronym for SOund and  
NAvigation Ranging. Sonar utilizes precision  
sound pulses or “pings“ which are emitted  
into the water in a teardrop-shaped beam.  
The sound pulses “echo“ back from objects  
in the water such as the bottom, fish, and  
other submerged objects. The returned  
echoes are displayed on the LCD screen.  
Each time a new echo is received, the old  
echoes are moved across the LCD, creating a  
scrolling effect.  
How Sonar Works  
1
Download from Www.Somanuals.com. All Manuals Search And Download.  
When all the echoes are viewed side by side, an  
easy to interpret “graph“ of the bottom, fish, and  
structure appears.  
The sound pulses are transmitted at various  
frequencies depending on the application. Very  
high frequencies (455 kHz) are used for greatest  
definition but the operating depth is limited. High  
frequencies (200 kHz) are commonly used on  
consumer sonar and provide a good balance  
between depth performance and resolution. Low  
frequencies (83 kHz) are typically used to achieve  
greater depth capability.  
The power output is the amount of energy  
generated by the sonar transmitter. It is commonly  
measured using two methods:  
• Root Mean Square (RMS) measures power  
output over the entire transmit cycle.  
• Peak to Peak measures power output at the  
highest points.  
The benefits of increased power output are the  
ability to detect smaller targets at greater distances,  
ability to overcome noise, better high speed  
performance, and enhanced depth capability.

DualBeam Sonar  
Your 500 Series™ Fishfinder uses a 200/83 kHz  
DualBeam sonar system with a wide (60°) area of  
coverage. DualBeam sonar is optimized to show  
the greatest bottom definition using a narrow  
(20°) beam yet can still indicate fish found in the  
wide (60°) beam when the Fish ID+feature is  
turned on. DualBeam is ideal for a wide range of  
conditions - from shallow to very deep water in  
both fresh and salt water. Depth capability is  
affected by such factors as boat speed, wave  
action, bottom hardness, water conditions, and  
transducer installation.

How GPS and Cartography Work  
Your 500 Series™ Fishfinder also supports GPS and chartplotting. It uses GPS  
and sonar to determine your position, display it on a grid, and provide detailed  
underwater information. The Global Positioning System (GPS) is a satellite  
navigation system designed and maintained by the U.S. Department of  
Defense. GPS was originally intended for military use; however, civilians may  
also take advantage of its highly accurate position capabilities, typically within  
+/- 10 meters, depending on conditions. This means that 95% of the time, the  
GPS receiver will read a location within 10 meters of your actual position. Your  
GPS Receiver also uses information from WAAS (the Wide Area Augmentation  
System), EGNOS (the European Geostationary Navigation Overlay Service), and  
MSAS (the MTSAT Satellite Augmentation System) satellites if they are  
available in your area.  
GPS uses a constellation of 24 satellites that  
continually send radio signals to the earth. Your  
present position is determined by receiving signals  
from up to 16 satellites and measuring the  
distance from the satellites.  
All satellites broadcast a uniquely coded signal  
once per second at exactly the same time. The GPS  
receiver on your boat receives signals from  
satellites that are visible to it. Based on time  
differences between each received signal, the GPS receiver determines its  
distance to each satellite. With distances known, the GPS receiver  
mathematically triangulates its own position. With once per second updates,  
the GPS receiver then calculates its velocity and bearing.

The GPS Receiver included with your 500 Series™ Fishfinder allows you to  
combine easy-to-use FishingGPS® chartplotter and navigation capabilities with  
advanced fishfinding.  
The following GPS functionality is currently supported by the 500 Series™  
Fishfinder when it is connected to the included GPS receiver:  
• View current position  
• View current track (breadcrumb trail)  
• View precision speed and heading from your GPS receiver  
• Save tracks, waypoints, and routes  
• Travel a route and navigate from one waypoint to the next.  
Your 500 Series™ supports Navionics® Gold, HotMaps™ and HotMaps™  
Premium on MMC or SD card media. You can insert optional-purchase cards in  
the (MMC)/SD slot on your control head to access additional detailed maps.  
See Multi-Media Card (MMC)/SD Slot for more information.  
NOTE: Your 500 Series™ supports Navionics® Gold, HotMaps™, and HotMaps™  
Premium. Your 500 Seriesdoes not support Navionics® Classic Charts or Platinum™  
Cartography.  
Your unit also comes with a built-in UniMap™ with a more detailed map of  
North America (Domestic models) or a more detailed map of Europe and  
Southeast Asia, including Australia and New Zealand (International models).  
Your 500 Series™ uses the GPS Receiver to determine the position of the boat  
automatically, and it uses the zoom level settings on a particular view to select  
the best chart to display. See Chart View: Viewing Cartography for more  
information.

Understanding the Sonar Display  
It is important to understand the significance of  
the display. The display does not show a literal 3-  
dimensional representation of what is under the  
water. Each vertical band of data received by the  
control head and plotted on the display represents  
something that was detected by a sonar return at  
a particular time. As both the boat and the targets  
(fish) may be moving, the returns are only showing  
a particular segment of time when objects were  
detected, not exactly where those objects are in  
relation to other objects shown on the display.  
The returned sonar echoes are displayed  
on the screen. As a new echo is received,  
the historical data scrolls across the screen.

Real Time Sonar (RTS™) Window  
A Real Time Sonar (RTS™) Window appears on the right side of the display in  
the Sonar View only. The RTS Windowupdates at the fastest rate possible for  
depth conditions and shows only the returns from the bottom, structure, and  
fish that are within the transducer beam. The RTS Windowplots the depth  
and intensity of a sonar return (see Sonar Menu Tab: RTS Window).  
The Narrow RTS Window  
indicates the sonar intensity  
through the use of colors. Red  
indicates a strong return and  
blue indicates a weak return.  
The depth of the sonar return  
is indicated by the vertical  
placement of the return on the  
display depth scale.  
The Wide RTS Window™  
indicates the sonar intensity  
through the use of a bar  
graph. The length of the  
plotted return indicates  
whether the return is weak or  
strong. The depth of the sonar  
return is indicated by the  
vertical placement of the  
return on the display depth  
scale. The Wide RTS  
Windowdoes not use  
grayscale.

Bottom Presentation  
As the boat moves, the unit charts the changes in depth on the display to create  
a profile of the Bottom Contour. The type of bottom can be determined from  
the return charted on the display. A Hard Bottom such as compacted sediment  
or flat rock appears as a thinner line across the display. A Soft Bottom such as  
mud or sand appears as a thicker line across the display. Rocky Bottoms have  
a broken, random appearance.

View Orientation  
Both Chart and Combo Views allow you to choose the orientation of the view.  
When North-Up orientation is selected, True North is shown at the top of the  
display. In other words, objects located to the north of the boat are drawn above  
the boat. When Course-Up orientation is selected, the direction of motion of the  
boat is shown at the top of the display. In other words, objects ahead of the boat  
are drawn above the boat. In both orientations, the view pans automatically, so  
that the boat is always centered on the display.  
When the boat is stationary, it is drawn as a circle. When the boat is in motion,  
it takes on a boat shape, pointed in the direction of motion (always Up in the  
Course-Up orientation).  
Viewing Cartography  
In the Chart or Combo Views there are several cartography-related functions  
that you can access using various keys.  
Panning: Use the 4-WAY Cursor Control  
key to move the chart around on the  
display in the direction of the key being  
pressed. When you do this, a bull's eye  
cursor is drawn at the center of the screen  
and is linked to the boat by a gray line,  
even if the boat is off the screen. At the  
same time, the temperature and speed  
boxes in the lower left corner are replaced  
with the distance and bearing from the  
boat to the cursor position and the  
latitude/longitude coordinates of the  
cursor.

amplified to reflect the level selected. If you zoom in so far that no cartography is  
available, a lat/long grid will be drawn instead.  
Decluttered Waypoints: When two or more waypoints overlap, or are displayed  
close together on a chart view, the screen will automatically declutter—  
waypoint names will shorten and the waypoint icons will change into small  
blue icons.  
To view a Decluttered Waypoint at full size, use the 4-WAY Cursor Control key  
to move the cursor onto a decluttered waypoint icon. When the cursor snaps  
onto the icon, the full-size waypoint name and icon will be displayed. You can  
also press the ZOOM+ key until you can see the individual waypoints on the

cursor is active, you will see information about the chart objects located near  
the cursor. If the cursor is not active, the Chart Info submenu will appear. Use  
the 4-WAY Cursor Control key to select the nearest port, the nearest tide  
station, or the nearest current station and see information about any of these  
objects.  
NOTE: The built-in UniMap™ does not contain any Port, Tide, or Current information.  
This information is only available from optional-purchase MMC/SD cards.

Introduction to Navigation  
Use your 500 Series™ Fishfinder to mark waypoints at areas of interest and to  
navigate to those waypoints via a savable route. A route represents the shortest  
intended distance between waypoints. You can also view and save tracks,  
which represent the actual path of the boat.

Waypoints, Routes, and Tracks  
Waypoints are stored positions that allow you to mark areas of interest or  
navigation points. Your Fishfinder can store up to 3000 waypoints.

Routes link two or more waypoints together to create a path for navigation and  
are used in trip planning. You can link individual waypoints together by using the  
GOTO key. A route represents your intended navigation and shows the shortest  
path from each waypoint to the next. As you travel a route, staying on the route  
line is the most efficient way to get to your destination, although you should  
always look out for obstacles not shown on the chart. Your 500 Series™  
Fishfinder can store up to 50 routes that can each contain up to 50 waypoints.  
Tracks consist of detailed position history and are displayed as a breadcrumb  
trail of trackpoints. The Current Track shows the position history since the unit  
was powered up (maximum of 20,000 trackpoints displayed). You can clear the  
Current Track or save it at any time. Your 500 Series™ Fishfinder can store up  
to 50 saved tracks, each containing 20,000 trackpoints. The current track  
represents your actual path so far.  
Save, Edit, or Delete a Waypoint  
Save your current position as a waypoint: On any view, press the MARK key to  
save the current position of the boat as a waypoint.

Normal  
Use Normal for on-the-water operation with a transducer connected. In  
addition, your Fishfinder uses advanced transducer detection methods to  
determine if a transducer is connected.  
If a functioning transducer is connected, Normal operation will be selected  
automatically at power up, and your Fishfinder can be used on the water.  
Exit Normal operation by powering your Fishfinder off.  
Simulator  
Use Simulator to learn how to use your Fishfinder before taking your boat on the  
water. The Simulator is a very powerful tool that provides a randomly-updated  
display which simulates on the water operation.  
Selecting Simulator from the Start-Up Options Menu allows you to pre-configure  
your Fishfinder for on the water operation. Any menu changes you make will be  
saved for later use. We recommend going through this manual while using the  
Simulator, since all of the menus function and affect the display in the same way  
as they would in Normal operation.  
NOTE: To get the full benefit of the Simulator, it is important to select Simulator  
manually from the Start-Up Options Menu as opposed to letting the Fishfinder enter  
Simulator automatically (as it will if a transducer is not connected and you do nothing  
during power up).  
A message will appear on the display periodically to remind you that you are  
using the Simulator.  
Exit the Simulator by powering your Fishfinder off.

Sensitivity  
Sensitivity controls how much detail is shown on  
the display and will adjust the sensitivity of all sonar frequencies. Increasing  
the sensitivity shows more sonar returns from small baitfish and suspended  
debris in the water; however, the display may become too cluttered.  
When operating in very clear water or greater depths, increased sensitivity  
shows weaker returns that may be of interest. Decreasing the sensitivity  
eliminates the clutter from the display that is sometimes present in murky or  
muddy water. If Sensitivity is adjusted too low, the display may not show many  
sonar returns that could be fish.  
Sensitivity at Low  
Sensitivity at Medium  
Sensitivity at High  
To adjust the Sensitivity:  
1. Highlight Sensitivity on the Sonar X-Press™ Menu.  
2. Press the RIGHT or LEFT Cursor keys to increase or decrease the  
Sensitivity setting. (Low = 1, High = 20, Default = 10)

Upper Range  
(Advanced: Sonar and  
Big Digits Views only)  
Upper Range sets the shallowest depth range that will be displayed on the  
Sonar and Big Digits Views. The Upper Range menu option is available when  
User Mode is set to Advanced (see Main Menu: User Mode) and can only be  
accessed from the Sonar and Big Digits Views. Upper Range is often used with  
Lower Range.  
For example, if you are only interested in the area between 20 and 50 feet deep,  
you should set the Upper Depth Range to 20 and the Lower Depth Range to 50.  
The Sonar View will then show the 30 foot area between 20 and 50 and will not  
show the surface or the bottom (assuming the bottom is deeper than 50 feet).  
Greater detail will be shown for the area between 20 and 50 feet.  
NOTE: A minimum distance of 10 feet will be maintained between the Upper and  
Lower Range regardless of the manual settings entered.  
To adjust the Upper Range:  
1. Make sure the User Mode is set to Advanced, then highlight Upper  
Range on the Sonar X-Press™ Menu.  
NOTE: See Main Menu: User Mode to change the User Mode to Advanced.  
2. Press the RIGHT or LEFT Cursor keys to increase or decrease the Upper  
Range setting. (0 to 990 feet or 0 to 327 meters [International Models  
only], Default = 0)

Lower Range  
Lower Range sets the deepest depth range that  
will be displayed by the unit. Auto is the default setting.  
Auto: The Lower Range will be adjusted by the unit to follow the bottom  
automatically. Auto is the default setting.  
Manual: You can adjust the Lower Range to lock the unit on a particular depth.  
“M” will be displayed in the lower right corner of the screen to indicate the unit  
is in Manual mode. Adjust the Upper and Lower Range together to view a  
specific depth range, especially when looking for fish or bottom structure.  
For example, if you are fishing in 60 feet of water but are only interested in  
the first 30 feet (surface to a depth of 30 feet), you should set the Lower  
Depth Range limit to 30. The display will show the 0 to 30 foot range, which  
allows you to see a more detailed view than you would see if the display  
went all the way to the bottom.  
NOTE: A minimum distance of 10 feet will be maintained between the Upper and  
Lower Range regardless of the manual settings entered.  
To adjust the Lower Range:  
1. Highlight Lower Range on the Sonar X-Press™ Menu.  
2. Press the RIGHT or LEFT Cursor keys to increase or decrease the Lower  
Range setting. (AUTO, 10 to 1000 feet, 3 to 330 meters [International  
Models only], Default = AUTO)

Chart Speed  
Chart Speed determines the speed at which the  
sonar information moves across the display, and consequently the amount of  
detail shown.  
A faster speed shows more information and is preferred by most anglers;  
however, the sonar information moves across the display quickly. A slower speed  
keeps the information on the display longer, but the bottom and fish details  
become compressed and may be difficult to interpret. Regardless of the Chart  
Speed setting, the RTS Windowwill update at the maximum rate possible for  
the depth conditions. Adjust Chart Speed to your personal preference.  
To adjust the Chart Speed:  
1. Highlight Chart Speed on the Sonar X-Press™ Menu.  
2. Press the RIGHT or LEFT Cursor keys to increase or decrease the Chart  
Speed setting. (1-9, Ultra, where 1 = Slow, 9 = Fast, Ultra = Fastest,  
Default = 5)

Fish ID+™  
Fish ID+™ uses advanced signal processing to  
interpret sonar returns and will display a Fish Symbol when very selective  
requirements are met. When a fish is detected, a fish icon and its depth are  
displayed above the return that has been classified as being a fish. Three different  
fish size icons represent the intensity of the sonar return and provide an indicator  
of relative fish size.  
DualBeam sonar models represent targets detected in the 200 kHz narrow  
beam as Orange Fish Symbols and targets detected in the 83 kHz wide beam  
as Blue Fish Symbols.  
83 kHz, Wide Beam  
Blue Fish Symbols  
200 kHz, Narrow Beam  
Orange Fish Symbols  
When Fish ID+™ is turned off, the Fishfinder shows only the raw sonar returns  
on the display. These returns will often result in “arches“ forming on the  
display, indicating potential targets. Due to the transducer beam angle, the  
distance to a fish decreases as the fish moves into the beam, and then  
increases as it moves out again, creating a Fish Arch when this distance change  
is shown on the display. Boat speed, chart speed, and the position of the fish  
within the sonar beam greatly affect the shape of the arch.  
Transducer Cone and Fish Arches  
To turn Fish ID+™ on or off:  
1. Highlight Fish ID+ on the Sonar main menu.  
2. Press the LEFT or RIGHT Cursor keys to turn the Fish ID+™ setting On or

Fish ID Sensitivity  
Fish ID Sensitivity adjusts the threshold of the  
Fish ID+™ detection algorithms. Selecting a higher setting allows weaker  
returns to be displayed as fish. This is useful for identifying smaller fish species  
or baitfish. Selecting a lower setting displays fewer fish from weak sonar  
returns. This is helpful when seeking larger species of fish.  
Fish ID Sensitivity is used in conjunction with Fish ID+™. Fish ID+™ must be  
On for Fish ID Sensitivity to affect the ability of the Fishfinder to identify sonar  
returns as fish.  
To change the Fish ID Sensitivity setting:  
1. Highlight Fish ID Sensitivity on the Sonar main menu.  
2. Press the LEFT or RIGHT Cursor keys to change the Fish ID Sensitivity

Max Depth  
(Advanced)  
Max Depth controls the maximum depth of operation. When Max Depth is set  
to Auto, the Fishfinder will acquire bottom readings as needed (within the  
capacity of the unit). When Max Depth is set to match your fishing maximum  
depth, your Fishfinder will not attempt to acquire sonar data below that depth,  
so more detail will be shown on the screen.  
NOTE: If the bottom is deeper than the Max Depth setting, the digital depth readout  
will flash, indicating that the Fishfinder cannot locate the bottom.  
NOTE: The Max Depth menu option is available when User Mode is set to Advanced

option is available when User Mode is set to Advanced (see Main Menu: User  
Mode).  
NOTE: Make sure that the Water Type is set accurately, especially in salt water,  
as this affects the accuracy of deep water depth readings. In salt water, what  
would be considered a large fish might be 2 to 10 times bigger than a large fish in  
fresh water (depending on the type of fish you are seeking). The salt water setting  
allows for a greater range in fish size adjustment to account for this difference.  
To change the Water Type setting:  
1. Make sure the User Mode is set to Advanced, then highlight Water  
Type on the Sonar main menu.

Troubleshooting  
Before contacting the Humminbird® Customer Resource Center, please read the  
following section. Taking the time to review these troubleshooting guidelines  
may allow you to solve a performance problem yourself, and therefore avoid  
sending your unit back for repair.  
Fishfinder Doesn’t Power Up  
If your Fishfinder doesn’t power up, use the Installation Guide that also comes  
with it for specific confirmation details, making sure that:  
• The power cable is properly connected to the Fishfinder control head.  
• The power cable is wired correctly, with red to positive battery terminal  
and black to negative terminal or ground.  
• The fuse is operational.  
• The battery voltage of the power connector is at least 10 Volts.  
Correct any known problems, including removing corrosion from the battery  
terminals or wiring, or actually replacing the battery if necessary.  
Fishfinder Defaults to Simulator with a Transducer Attached  
A connected and functioning transducer will cause the newly-started  
Fishfinder to go into Normal operating mode automatically. If, when you power  
up the Fishfinder, it goes into Simulator mode automatically, even though a  
transducer is already connected, this means that the control head is not  
detecting the transducer. Perform the following troubleshooting tasks:  
• Using the Installation Guide that also comes with your Fishfinder, check  
to make sure that the transducer cable is securely connected to the  
Fishfinder. Reconnect if necessary, and power up the Fishfinder again  
to see if this fixes the problem.  
• Replace the non-functioning transducer with a known good transducer  
if available and power up the control head again.  
• Check the transducer cable. Replace the transducer if the cable is  
damaged or corroded.

Display Problems  
There are several main conditions or sources of possible interference that may  
cause problems with the quality of the information displayed on the control  
head. Look in the following table for some symptoms of display problems and  
possible solutions:  
Problem  
Possible Cause  
The control head loses  
power at high speeds.  
If the power output of your boat’s engine is unregulated,  
the control head may be protecting itself using its  
over-voltage protection feature. Make sure the input  
voltage does not exceed 20 Volts.  
When the boat moves  
at higher speeds, the  
bottom disappears or  
suddenly weakens, or  
the display contains  
gaps.  
The transducer position may need to be adjusted. A mix of  
air and water flowing around the transducer (cavitation)  
may be interfering with the interpretation of sonar data.  
See your Installation Guide for suggestions on adjusting the  
transducer position.  
Electrical noise from the boat’s engine may be interfering  
with sonar reception. See Finding the Cause of Noise for  
more information.  
There are no fish  
Sonar readings may be affected if the transducer is not  
positioned correctly (i.e. mounted at an angle, not straight  
down), or there is some kind of mechanical interference,  
either because it is mounted inside a hull that is too thick  
for proper sonar transmission, the bond between the  
transducer and the hull is not airtight, or because the  
transducer is dirty. Check with your Installation Guide for  
guidance on re-positioning the transducer, and make sure  
the transducer is clean.  
detected, even when  
you know they are in  
the water under the  
boat, or sonar readings  
seem weak or faulty.  
Low battery voltage may be affecting the power of signal  
transmission.

with sonar reception. See Finding the Cause of Noise for  
more information.

Finding the Cause of Noise  
Electrical noise usually affects the display with many black dots at high speeds,  
and high sensitivity readings. One or more of the following sources can cause  
noise or interference:  
Possible Source of Noise  
Other electronic devices  
Isolation  
Turn off any nearby electronic devices to see  
if the problem goes away, then turn them on  
one at a time to see if the noise re-appears.  
To determine whether the boat’s engine is the  
source of the noise, increase the RPMs while  
the boat is in neutral and stationary to see if  
the noise increases proportionately; if noise  
appears when you rev the engine, the  
problem could be the spark plugs, alternator,  
or tachometer wiring. Replace the spark plugs  
with resistor plugs, install an alternator filter,  
or route the control head power and  
transducer cables away from the engine  
wiring.  
The boat’s engine  
Turbulence created by the propeller can cause  
noise; make sure the transducer is mounted  
at least 15” (38 cm) from the propeller, and that  
the water flows smoothly over the face of the  
transducer at all times.

Glossary  
Sonar Terms:  
Alarm, Depth: Depth Alarm is a user-controllable, audible alert that sounds  
when depth is less than or equal to the setting.  
Alarm, Temperature: Temperature Alarm is a user-controllable, audible alert  
that sounds when the water surface temperature equals the setting.  
Backlight: Backlight is a user-controllable illumination for the LCD for night and  
low light use.  
Beam (Sonar Beam): A sonar beam is the wide, cone-shaped projection of  
sound waves formed as sound travels underwater. See Cone Angle.  
Big Digits View: Big Digits View is a Humminbird® feature that displays the sonar  
graph and enlarged digital readouts for easy reading from a distance. This is a  
great tool when monitoring the digital depth is important - such as with higher  
boat speeds, or when viewing the unit from a distance. When speed input is  
available, the Big Digits View also shows the TripLog. See TripLog.  
Bottom Black: Bottom Black is a Humminbird® feature that “fills in“ the area of  
the display below the bottom contour. Bottom Black is preferred by some  
anglers because of its high contrast and easy readability, even though it can  
obscure bottom hardness information.  
Bottom Contour: Bottom Contour is the profile of the bottom graphed to the  
display as the depth changes.  
Bottom Hardness: Bottom Hardness is the density (or composition) of the  
bottom, which can often be determined by interpreting the main sonar return.  
Varying levels of hardness can be determined by interpreting the “thickness“ of  
the sonar return. Hard returns appear thin and black, softer returns appear  
thicker and less black. It is important to note that a sonar return from a sloping  
bottom can have the appearance of a softer bottom.  
Cavitation: Cavitation is the effect of air bubbles created as the propeller  
rotates and the boat moves through the water.

Chart Speed: Chart Speed is a user-controllable feature that sets the speed at  
which sonar information moves across the display. A faster setting displays  
sonar information from more pings and shows more detail, but the information  
moves quickly across the display: a slower setting permits viewing of more  
sonar history, but does not display as much detail. The best setting is often the  
user’s personal choice.  
Cone Angle: The cone angle is the angular measurement of the sonar beam at  
a specific dB down point (i.e. -10 dB). See dB Down Point.  
Customizable Digital Readouts: Customizable Digital Readouts is a  
Humminbird® feature that permits the user to select the specific digital  
information that appears in the main Sonar view (i.e. Speed, Temperature,  
Barometric Pressure, TripLog, etc.)  
Dead Zone: The dead zone is the area of the sonar beam that receives the sonar  
signal after the main bottom return. Fish and other objects close to the bottom  
that fall within the dead zone will probably not be visible in the sonar beam.  
Precision sonar beams, such as the Humminbird® 20° beam, have a smaller  
dead zone than wider sonar beams.  
Decibel: A Decibel is the measurement for sound pressure level, or  
“intensity”of the sonar return. See dB Down Point.  
dB Down Point: The dB Down Point is the standard decibel level at which the  
sonar cone angle is measured, and is written as “@ -10 dB” or “@ -3 dB“.  
Measurements at smaller down points (bigger negative numbers) indicate that  
the less intensive sonar signals are being used for the measurement.  
Display, FSTN: FSTN is an acronym for Film Super-Twist Nematic. FSTN is a  
monochrome display technology characterized by black, high-contrast pixels.  
All monochrome fixed mount Humminbird® products use FSTN technology.  
DualBeam PLUS™: DualBeam PLUS™ is a Humminbird® sonar configuration  
that uses two sonar beams simultaneously, and combines the information from  
both beams into one view by overlapping the data on-screen, or shows each  
beam individually side by side, or permits each beam to be viewed individually  
full screen.

Feature Memory: Feature Memory is a Humminbird® feature that retains the  
user’s menu settings in permanent memory. Settings are retained even when the  
unit is powered off indefinitely.  
Fish Arch: A Fish Arch is the apparent “arch“ that appears on the display when  
any object moves through the sonar cone. The arch results from a gradual  
decrease in distance to an object as it moves into the sonar cone. The distance to  
an object changes due to the conical shape of the sonar beam, which causes the  
distance to be greater at the edges of the beam than at the center of the beam.  
When this distance change is graphed on the display, an arch appears.  
Fish ID+™: Fish ID+™ is a Humminbird® feature that uses advanced sonar  
processing algorithms to determine if a detected object is likely to be a fish. When  
the sonar signal from an object meets strict parameters, the unit draws a Fish  
Symbol (or icon) and the digital depth of the target. On DualBeam and DualBeam  
PLUS™ units, fish detected in the narrow center beam are shown as shaded  
symbols, and fish detected in the wider beam are shown as hollow symbols.  
Fish Symbol: A Fish Symbol is the graphic that is displayed on the screen when  
Fish ID+determines that a sonar return is likely to be a fish. See Fish ID+.  
Freeze Frame: Freeze Frame is a Humminbird® feature that pauses the sonar  
scrolling so that the image on screen can be studied with greater detail. See  
Instant Image Update.  
Frequency: Frequency is a measure of the number of sound wave cycles per  
second of a sound impulse transmitted underwater. A typical frequency for  
fishfinders is 200 kHz, which offers a good balance of performance under many  
conditions. Lower frequencies, such as 50 kHz, are capable of penetrating to  
greater depths, but with less resolution. Higher frequencies, such as 455 kHz, offer  
greater resolution, but are limited in depth performance. Humminbird® uses a  
variety of frequencies that are optimized for specific applications.  
Grayscale: Grayscale is the use of varying shades of gray to represent the  
strength of the sonar signal on the display , and is a very intuitive method of  
presenting information. Traditionally, the strongest sonar signals are  
represented in black, and progressively weaker signals are represented in  
progressively lighter shades of gray.  
Glossary

Grayscale, Inverse: Inverse Grayscale is a Humminbird® feature that reverses the  
correlation of sonar signal strength and the shade of gray typically used to  
represent it. The strongest sonar signals are represented by “white“, and  
progressively weaker signals are represented in progressively darker shades of  
gray. While somewhat counter-intuitive, this method makes the sonar images  
crisper, and has the benefit of enhancing the apparent sensitivity because the  
weaker signals appear bolder. Inverse grayscale works well in very clear water.  
Debris-laden water often appears as a lot of clutter on the screen.  
Instant Image Update: Instant Image Update is a Humminbird® feature that  
updates all the sonar information on the display when Sensitivity and a variety of  
sonar settings (Bottom View, Range, etc.) are modified. This differs from the  
traditional functionality that only updates the new sonar information collected  
after the setting change. Instant Image Update permits more accurate fine-tuning  
of the display because the user can see the results on the complete sonar graph.  
When combined with the Freeze Frame feature, the user can adjust and  
understand the effects of many different sonar settings quickly and easily.  
Maximum Depth Menu: The Maximum Depth Menu is a Humminbird® feature  
that optimizes performance based on the maximum operational depth set by the  
user. Many Humminbird® units can operate across a very broad depth range (up  
to 2500 feet) which causes the unit to “look“ up to that full depth under some  
circumstances. Due to the speed of sound in water, this can result in less  
responsiveness because the unit has to wait for a longer period of time to receive  
the sonar signal. When the Maximum Depth menu is set to a lower value, the unit  
only looks up to the setting, which increases the responsiveness of the unit. This  
is an important feature for anyone operating in shallower depths!  
Noise: Noise is unintentional, external sound waves that interfere with the optimal  
operation of sonar. Noise appears as random “dots“ on the display, and is caused  
by a variety of sources. Electrical noise (from trolling motors, bilge pumps, VHF  
radios) typically manifests as a consistent dot pattern. Electrical noise can be  
isolated by selectively turning on and off other electrical devices to determine the  
source. Often re-routing the power cable, or connecting to an alternative power  
supply (second battery) can help overcome electrical noise. Hydrodynamic noise  
(from propeller and/or hull cavitation) has a more random appearance and is  
generally related to boat speed, so that faster operation results in more noise.  
Hydrodynamic noise can be overcome by proper transducer installation. Many  
Glossary

Humminbird® products have a Noise Filter menu setting that allows the user to  
clear the screen of noise that is difficult to eliminate.  
Pixels: Pixels are the “picture elements“, or small square blocks, that make  
up the image on the LCD. Measured as a vertical by horizontal number  
(i.e. 640V x 320H), this key specification typically indicates the quality of  
resolution. In fishfinders, the total resolution (vertical multiplied by horizontal)  
is often less important than the “Vertical Pixel“ resolution. See Pixels, Vertical.  
Pixels, Vertical: Vertical Pixels are a number of vertical picture elements in a  
single column on an LCD display. A greater number of vertical pixels provide finer  
resolution of targets detected by sonar. Essentially, a vertical distance (the depth),  
when divided by a larger number, breaks that distance into smaller samples, each  
representing a smaller area and thus providing more detail. In fishfinders, vertical  
pixels are more critical than horizontal pixels because the horizontal axis of the  
display represents time, or history. Sonar information on the horizontal axis can  
vary greatly, depending on boat speed and the Chart Speed setting. A greater  
number of horizontal pixels show more sonar history that the boat has passed  
through. On many models, Humminbird® provides the most vertical pixels to  
provide a better display resolution. See Chart Speed and Pixels.  
Power Output: Power output is the amount of sound energy emitted into the  
water by the sonar transmitter. Power output is measured using either RMS (Root  
Mean Square) or P-T-P (Peak-to-Peak) measurement systems. Either method is  
acceptable, but it is important, when comparing power outputs, to make sure that  
the same measurement system is being used for both outputs, because P-T-P  
numbers are 8 times higher than RMS numbers. Greater power output allows the  
sonar signal to penetrate through weeds and thermoclines, reach deeper depths  
and operate more effectively in noisy environments, such as when the boat is  
running at high speed.  
Pulse Width (Pulse Length): Pulse Width is the length of time that a sonar sound  
burst is transmitted into the water. Shorter pulse widths provide better target  
separation, but cannot travel to great depths. Longer pulse widths provide better  
depth penetration, but result in poorer target separation. Humminbird® varies  
pulse width based on depth to optimize both target separation and depth  
performance. See Target Separation.

QuadraBeam PLUS™: QuadraBeam PLUS™ is a Humminbird® sonar  
configuration that uses four sonar beams for a more detailed bottom image.  
QuadraBeam PLUS™ uses the DualBeam PLUS™ configuration for downlooking,  
and also adds two additional beams to look to the left and right. The sonar beams  
pointing to the left and right provide the ability to spot fish and structure over a  
wide 90° area, and to identify on which side of the boat they are located. See  
DualBeam PLUS™.  
Quick Disconnect Mount: The Quick Disconnect Mounting system is an  
exclusive Humminbird® feature that permits the unit to be easily removed from  
the mounting base by pressing a release button, and re-installed by simply  
snapping it back into place. All cable connections are made when installing, so  
that no separate wiring connections are required. Additionally, the mount offers  
90° tilt and 360° swivel capability to adjust the viewing angle of the unit as you  
move about the boat.  
Real Time Sonar: Real Time Sonar is a Humminbird® technology that delivers  
ultra-fast sonar transmitter/receiver operation and results in a more detailed  
instantaneous view of what is under the boat. The Real Time Sonar window  
is a vertical band at the right side of the display that shows the instantaneous  
sonar return from the transducer at a particular instant. The RTS Window™  
menu option permits the user to adjust the window to show the full sonar  
signal return, or just a narrower band that indicates intensity using grayscale.  
Real Time Sonar relies on very fast Sonar Update Rate (Ping Speed). See  
Sonar Update Rate.  
Receiver: See Transmitter.  
Second Return: The Second Return is a term that describes the appearance of  
a second sonar return below the primary sonar return (bottom contour) at  
exactly twice the true depth. The second return is caused by the same sonar  
energy bouncing off the bottom once, rebounding to the water surface and  
then traveling back down to the bottom to be reflected again. Second returns  
are more common in shallow water and over hard bottoms; it is actually  
possible to see a third sonar return under some circumstances. The second  
return provides useful information to help determine bottom hardness, as areas  
with harder bottoms will generally create a second return. The second return  
can be used as a guide to set Sensitivity when in shallower water.  
Glossary

Sensitivity: Sensitivity is a user feature that adjusts the sensitivity of the sonar  
system to show more or less detail in the water. Higher sensitivities are often  
preferred, however, when the water contains debris (silt, storm debris, etc.) and it  
can be difficult to pick out targets. Conversely, if sensitivity is set too low, relevant  
targets may be missed.  
SONAR: SONAR is the acronym for SOund and NAvigation Ranging. Sonar  
technology uses precision sound bursts transmitted underwater to determine the  
distance and other attributes of objects in the water. Distance can be determined  
because the speed of sound in water is constant, and the time for the signal to  
return is measured. Sound also travels very quickly underwater, making sonar a  
responsive, cost-effective tool. Sonar is the basic technology behind all  
recreational and commercial fishfinding and depthfinding devices.  
Sonar Echo Enhancement: Sonar Echo Enhancement is a Humminbird® feature that  
describes the high degree of sonar sensitivity achieved through a combination of  
transmitter/receiver and software algorithms. The result of Sonar Echo Enhancement  
is to display virtually everything in the water that is of interest to the angler, including  
bait fish, game fish, thermoclines, weed beds, subtle structure, and more.  
Sonar Update Rate: Sonar Update Rate is the number of times per second that  
the transmitter/receiver sends and receives sonar signals. A very fast sonar update  
rate collects more information and provides a more detailed image of the bottom,  
fish and structure. Many Humminbird® units operate at up to 40 times per second  
when in single frequency operation. Due to the limitation of the speed of sound in  
water, the update rate begins to slow as depth increases to deeper than 50 feet.  
In very shallow water (less than 10 feet), however, update rates as much as 60  
times per second can be achieved.  
Speed: Speed is the rate at which the boat moves through the water. Boat speed  
can be measured as Speed Over Ground or Speed Through Water. Speed Over  
Ground is provided by GPS, and is the measurement of the boats progress across  
a given distance. Speed Through Water is provided by a speed paddlewheel, and  
is the measurement of the flow past the boat, which may vary depending on  
current speed and direction. Speed Through Water is most critical for anglers  
using downriggers, as it impacts the running depth of the down riggers. Speed  
Over Ground is optimal for navigation, as accurate destination times can be  
derived from this measurement. Humminbird® products allow for input and  
display of both sources.

Structure: Structure is a general term for objects on the bottom that present a  
discontinuity and are a likely attractor for fish. This includes bottom contour  
features (drop-offs, humps, and holes), standing structure (stumps, timbers, brush  
piles) and a wide range of other potential objects (sunken boats, reefs).  
Humminbird® units excel at showing structure with great detail over a wider area  
due to unique sonar configurations developed for the angler.  
Structure ID®: Structure ID® is a Humminbird® feature that describes the  
traditional grayscale method of presenting sonar information. See Grayscale.  
Surface Clutter: Surface Clutter is a phenomenon where sonar returns are  
reflected off of tiny objects near the surface of the water, including algae and even  
air bubbles. Typically, saltwater environments have significantly greater surface  
clutter than freshwater due to continuous wind and wave action that causes  
aeration at the surface. The Surface Clutter menu provides manual control to bias  
the default settings under extreme conditions.  
Target Separation: Target Separation is the measurement of minimum distance that  
a fishfinder needs to be able to recognize two very close objects as two distinct  
targets (i.e. two fish hanging very close, or a fish hanging very close to structure).  
Humminbird® fishfinders provide a very good 2 1/2 inches of target separation in  
shallower than 100 feet of depth. Target separation decreases as depth increases  
due to the need for longer Pulse Width to achieve greater depth. See Pulse Width.  
Thermoclines: Thermoclines are water layer(s) of distinctly different temperatures  
that create a sonar reflection due to the density of the differing water  
temperatures. Typically a thermocline will appear as a continuous band across the  
display at some distance above the bottom contour. Thermoclines are of interest  
to anglers because fish will suspend above or below the thermocline as they seek  
the optimum temperature and oxygen levels.  
Time Variable Gain: Time Variable Gain is a processing step applied to the sonar  
return to “normalize“ the data so that objects of equal size (i.e. fish) appear to be  
the same size, even if they are separated by a good distance. Time Variable Gain  
is a fundamental attribute of good sonar, but is often promoted as a feature.  
Total Screen Update®: A Humminbird® feature that refreshes and updates all the  
sonar information on the display when a range change occurs. Without Total  
Screen Update®, only the most recent sonar information would be drawn to the

new range, and the old sonar information would continue to scroll off the screen  
at the old range.  
Transducer: The transducer is part of the sonar system, which mounts on the  
boat and is in contact with the water, that converts the electrical energy from  
the transmitter into sound energy, and that forms the sonar beam in turn.  
Internally, the transducer consists of one or more piezo electric disks that  
expand by very minute amounts to create the sound wave. This element also  
works in reverse, converting the returned sound energy back into an electrical  
signal that the receiver interprets. Transducers are available for many specific  
mounting applications for the boat, such as a transom mount, trolling motor  
mount, etc. Humminbird® offers many sophisticated transducers, often with  
multiple piezo electric elements designed to form specifically-shaped sonar  
beams, providing the angler with superior tools for finding and catching fish.  
See Transmitter and SONAR.  
Transmitter: The transmitter and receiver are matched parts of the sonar system  
that send (transmit) and listen to (receive) the sonar signals, and work in  
conjunction with the transducer. Humminbird® transmitters have an extremely fast  
cycling design that can send signals up to 60 times per second, as well as produce  
the varying levels of power output needed for different depths and conditions.  
Additionally, the transmitter has the capability to create very precise sonar pulses  
needed for a high degree of target separation. Humminbird® receivers are  
extremely sensitive, but within a narrow “bandwidth“ to discriminate against  
noise from external sources. Additionally, the receiver offers a wide “dynamic  
range“ which provides the ability to receive very strong signals alternating with  
very weak signals, without the strong signal overwhelming the weak signal.  
See Transducer and Noise.  
TripLog: TripLog is a Humminbird® feature that provides an on-screen counter for  
Elapsed Time, Average Speed and Total Distance traveled, and requires a speed  
input to activate the feature. TripLog appears on the Big Digits View, and can be  
reset to zero through the TripLog menu.  
TrueArch®: TrueArch® is a Humminbird® feature that provides true fish arches, not  
artificial arches or symbols. Humminbird® units are capable of producing fish  
arches due to the wide 60° sonar beam of DualBeam PLUS™, an extremely  
sensitive sonar receiver. See Fish Arch.

Viewing Angle: Viewing Angle is an attribute of an LCD that characterizes visibility  
of the display when viewing from off the central access, such as when standing  
to the side of the fishfinder. Wider viewing angles are better because the  
information remains visible even when viewing from the side.  
WhiteLine: WhiteLineis a Humminbird® feature that highlights the  
strongest sonar return on the display using a very light gray band. This is  
preferred by some anglers who have grown accustomed to the feature on  
paper graph chart recorders.  
WideSide®: WideSide® is a Humminbird® sonar configuration used in an optional  
transducer. WideSide® uses three sonar beams pointing to the left, right and  
down. Beams pointing to the left and right are effective for spotting fish and  
structure near the surface or on the bank. The downlooking beam provides depth  
information directly below the boat.  
X-Press™ Menu: X-Press™ Menus are a Humminbird® feature that make the  
most commonly-used menu selections available with one press of the MENU key.  
Items that appear on the X-Press™ Menu are related to the current view, and  
present the most logical options for that view. Sonar View X-Press™ menus will  
differ from Chart View X-Press™ menus, etc. X-Press™ menus are one of the  
principal reasons that Humminbird® products are easier to use.  
Zoom: Zoom is a feature that focuses in on a smaller area of the bottom to provide  
enhanced resolution. With enhanced resolution, the angler can more easily see  
fish hanging in structure or multiple fish hanging close together. Split screen zoom  
divides the display into the full range view on the right, and the zoomed view on  
the left. Humminbird® offers One-Touch® Zoom which allows the zoom feature to  
be easily accessed from the regular sonar view with just one key press, eliminating  
the need to use menus to access the feature.  
Zoom, Bottom Lock: Bottom Lock Zoom is a feature that focuses on a smaller area  
just above the bottom to provide enhanced resolution. Unlike regular zoom, it  
continuously graphs the bottom at a constant point on the display regardless of  
changes in depth. This “flattens“ out the bottom contour, but is effective at  
showing fish on or near the bottom, and is preferred by many saltwater anglers.

GPS & Navigation Terms:  
Acquisition Time: The length of time that a GPS receiver typically takes to  
determine a position from at least three satellites. Humminbird® GPS receivers  
provide very fast acquisition times (under one minute), permitting users to get out  
on the water faster.  
Alarm, Arrival: The audible alert that sounds when the boat is equal to or less than  
the alarm setting (25 feet – 3000 feet) from the location of the destination waypoint.  
Alarm, Drift: Drift Alarm is an audible alert that sounds when the boat is equal to  
or over the alarm setting (25 feet – 3000 feet) from the location where the alarm  
was turned on.  
Alarm, Off-Course: Off-Course Alarm is an audible alert that sounds when the  
boat’s distance from the intended Track, (Cross Track Error), is equal to or over the  
alarm setting (25 feet – 3000 feet). See Track and Cross Track Error.  
Altitude: Altitude measures height above sea level. Altitude is a measurement that  
can be provided by GPS.  
Bearing (BRG): Bearing is the direction to a destination waypoint measured in  
degrees from North (i.e. 321°, where 000° is North, 090° East, 180° is South,  
270° is West).  
Chartplotter: Chartplotter describes a navigation device that shows Present  
Position on a Map, along with Tracks, Waypoints, and Routes. All Chartplotters are  
also considered Trackplotters. All Humminbird® GPS Combo units are  
Chartplotters. See Trackplotter.  
Cold Start: Cold Start refers to the procedure that a GPS receiver must perform  
when it does not have historical information regarding its current location. This  
procedure typically lasts for several minutes, and may be experienced upon first  
power up of the receiver, or if the receiver has been moved a great distance.  
Course Over Ground (COG): Course Over Ground is the current direction the boat  
is traveling measured in degrees from North (i.e. 321°, where 000° is North, 090°  
East, 180° is South, 270° is West). When the Course Over Ground is equal to  
Bearing, the boat is said to be “On Course” and will arrive at the destination in the  
most efficient manner. COG is often confused with Heading. See Heading.

Cross Track Error (XTE): Cross Track Error is the straight-line distance of the boat  
from the intended Track. XTE measures how far the boat is off course, and also  
triggers the Off Course Alarm. See Track.  
Differential GPS (DGPS): Differential GPS is a system to improve the position  
accuracy of the Department of Defense GPS through the use of secondary  
“correction signals” broadcast from ground stations around the coastal United  
States and on some inland waterways. These correction signals are provided by  
the USCG and received by an auxiliary Differential Beacon Receiver (DBR) that  
connects to the GPS receiver. The advent of WAAS has largely negated the need  
for the added expense of a DBR in the United States.  
Distance To Go: Distance To Go is the straight-line distance between Present  
Position and the Destination Waypoint. DTG and SOG (Speed Over Ground) are  
used to calculate Time To Go. See Time to Go and Speed Over Ground.  
Estimated Position Error (EPE): Estimated Position Error is a calculation that  
indicates the potential position inaccuracy the user may experience due to a  
variety of GPS factors which include satellite position in the sky, signal strength  
and others factors.  
Fix Type: Fix Type indicates whether the GPS receiver is providing 2D fix or 3D fix. A  
2D fix requires only three satellites and provides only latitude and longitude. A 3D fix  
requires four or more satellites, and provides latitude, longitude and altitude.  
GPS: GPS is an acronym for Global Positioning System. GPS provides accurate  
position (latitude, longitude, altitude) information virtually anywhere on the earth  
through satellite technology and personal receivers on the ground. A series of  
geosynchronous satellites broadcast a unique signal toward the earth once per  
second. A GPS receiver, such as that included with many Humminbird® products,  
receives the signals from these satellites and is able to determine position based  
on very slight differences in the time each signal is received and the receiver’s  
knowledge of the location of each of the satellites.  
Heading: Heading describes the direction the boat is pointing and is measured in  
degrees (i.e. 321°, where 000° is North, 090° East, 180° is South, 270° is West).  
Due to wind and waves, the boat is often traveling in a slightly different direction  
than it is heading, and therefore Heading is often confused with Course Over  
Ground. See Course Over Ground.

Map Datum: A Map Datum refers to a particular survey of the earth’s surface that  
was referenced when creating a chart (i.e. WGS84). Since the earth is not flat, and  
not even consistently round, a mathematical model must be used to translate  
coordinates from the sphere of the earth to the flat surface of a chart. This  
mathematical model is the Map Datum. Historically, many different Map Datums  
have been used around the world to create maps; often a reference to the Map  
Datum can be found in the legend of a paper map. It is important to select the  
correct Map Datum setting in your fishfinder when comparing GPS position to a  
paper chart to avoid slight position inaccuracies. Almost all electronic charts use  
the WGS84 Map Datum and therefore, they do not require setting changes.  
MMC: MMC is an acronym for Multi Media Card. An MMC is a postage stamp-  
sized memory device used to store electronic data such a maps, waypoints, routes  
and other information. MMC is a very rugged format suitable for the marine  
environment, but it is not waterproof. The MMC is removable from Humminbird®  
products, and can be used in a PC that is equipped with an appropriate card  
reader. MMC is the same format that many digital cameras use. See SD.  
North, Magnetic: North is the principle reference point of the compass (i.e. North  
is 000°). Magnetic North relies on the earth’s magnetic field to align a metal  
pointer generally towards True North. However, due to local variations in the  
earth’s magnetic field around the globe, the difference between True North and  
Magnetic North can be greater than 10°. See True North.  
North, True: North is the principle reference point of the compass (i.e. North is  
000°). True North uses the axis of the rotation of the earth as the reference for  
North and is constant for all points on the earth. Most GPS units default to True  
North as the setting. The GPS heading may vary from the boat compass heading  
because the compass uses Magnetic North. Humminbird® GPS units provide the  
option of selecting True or Magnetic readouts by using the North Reference menu.  
See Magnetic North.  
Present Position: Present Position is the current location (latitude, longitude)  
determined by GPS. The Present Position is indicated on-screen by a directional  
boat icon if the boat is moving, or a round symbol if the boat is stationary.  
Route: A Route is series of waypoints linked together in a specific sequence to  
define a navigation path between two points, and saved in the fishfinder’s

memory. Routes are often used when frequently traveling between two or more  
locations because it is a faster and more accurate method than repeatedly  
selecting individual waypoints each time one travels through the same area.  
Routes consist of a Start Waypoint, an End Waypoint, and a series of waypoints  
in between. Users can begin navigation at the beginning, the end (to run the route  
in reverse) or at any waypoint in between. See Waypoint.  
SD: SD is an acronym for Secure Digital. An SD card is virtually identical in  
function to an MMC; however, the speed at which information can be accessed is  
generally faster, the storage capacity is generally larger, and the card has security  
features which can be used to prevent extracting the data from the card. SD is the  
same format that many digital cameras use. See MMC.  
Selective Availability: Selective Availability (SA) is a GPS system “feature” that  
can be implemented by the U.S. Department of Defense (DoD) to degrade the  
accuracy of GPS positioning information. With SA active, the GPS is accurate to  
within 100 meters 95% of the time. With SA inactive, the GPS is accurate to within  
45 meters 95% of the time. Currently, SA is inactive and the consumer can enjoy  
the greater precision GPS provides; however, the DoD reserves the right to activate  
SA at any time.  
Speed Over Ground (SOG): Speed Over Ground is the measurement of the boat’s  
progress across a given distance, and is the speed measurement provided by GPS.  
An alternate, Speed Through Water, is provided by a speed paddlewheel, and is  
the measurement of the flow past the boat, which may vary depending on current  
speed and direction. Speed Over Ground is optimal for navigation because  
accurate destination times can be derived from this measurement. Humminbird®  
products allow for input and display of both speed measurements.  
Time To Go (TTG): Time To Go is the estimated time required to reach the destination  
waypoint. TTG is calculated using the SOG and DTG. See SOG and DTG.  
Track: A Track is a series of saved points that define the past path of the boat.  
These Track Points are saved at regular time intervals. Tracks are a useful and quick  
method to see where you’ve been, and an easy guide to follow to get you back to  
the starting point. Generally, all GPS units have a limited number of Track Points  
that can be saved before the unit runs out of memory and begins erasing the first  
track points saved. Because of this, the user can adjust the Track Point Interval

menu to increase the amount of time between when points are saved, and thus  
extend the distance covered by a track. Tracks can also be permanently saved to  
memory, and re-displayed at the user’s option.  
Track Line (TRK): The Track Line is the planned line of travel between two  
waypoints, and it represents the most efficient path between the two points  
because it is a straight line. The TRK is measured in degrees (i.e. 321°, where 000°  
is North, 090° East, 180° is South, 270° is West). See Cross Track Error and  
Course Over Ground.  
Trackplotter: Trackplotter describes a navigation device that shows Present  
Position, along with Track, Waypoint, and Routes, but NO MAP in the background.  
See Chartplotter.  
Trolling Grid: Trolling Grid is a Humminbird® feature that displays a precise  
reference grid around a waypoint. This grid is used as a guide pattern for trolling  
around a specific area to assure a more efficient and complete coverage of that  
area. Trolling Grid resolution be changed by zooming in or out on the chart. The  
Trolling Grid can also be rotated on the display to orient it for optimal boat course  
for wave and wind conditions.  
UTC: UTC is an acronym for Universal Time Constant. UTC is the “standard time”  
used in navigation, and is the local time in Greenwich England. (UTC is equivalent  
to Greenwich Mean Time (GMT)). To display the correct Local Time in a  
Humminbird® GPS unit, the user must use the Local Time Zone menu and select  
the time zone (i.e. EST, CST).  
WAAS: WAAS is an acronym for Wide Area Augmentation System. WAAS is  
complementary technology to GPS that provides enhanced accuracy through  
correction signals broadcast from Federal Aviation Administration WAAS satellites  
stationed over the USA. These secondary signals are automatically received by the  
standard Humminbird® GPS Receiver. With WAAS signal, GPS accuracy is  
improved to within 3 meters 95% of the time. Outside the United States, regional  
governmental coalitions have created similar systems such as EGNOS (Europe)  
and MSAS (Japan).

Waypoint: A Waypoint is the saved location (latitude, longitude) of a point of  
interest that is stored in a GPS receiver’s memory. This can include a marker buoy,  
dock, fishing hole or anywhere else the user may want to return to. Humminbird®  
products offer the ability to name and assign a symbol to the saved location.  
Depth, Date and Time of Day when the waypoint was created is also saved.  
Waypoint Target: Waypoint Target is a Humminbird® feature that displays a  
precise “bull’s eye” around a selected waypoint. This bull’s eye is used to easily  
monitor boat position relative to a waypoint, and is useful for fishing over  
submerged structure. With Waypoint Targets, a quick look at the screen lets you  
know how far off the waypoint the boat has drifted.
