How GPS and Trackplotting Work  
Your Humminbird® 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 4.5 - 10 meters, depending on conditions and your Humminbird®  
model. This means that 95% of the time, the GPS receiver will read a location  
within 4.5 - 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 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  
 
1
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 allows you to combine easy-to-use trackplotting and navigation  
capabilities with advanced fishfinding. The following GPS functionality is currently  
supported by your Fishing System 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 and waypoints  
• Travel a route and navigate from one waypoint to the next.  
Connecting a GPS Receiver to the Fishfinder  
Here's how to access GPS functionality using your GPS Receiver Accessory:  
1. Attach the GPS receiver to your Fishfinder Control Head COM port using  
the NMEA cable attached to the antenna.  
2. If you are already using other Fishfinder accessories plugged into the COM  
connector, you will also need to use the AS-YC ("Y") cable included in your  
GPS Hardware Kit so that you can use both the accessories and your GPS  
Receiver at the same time. Attach the COM connector of the "Y" cable  
directly to your Fishfinder Control Head COM port. Attach the GPS receiver  
to the NMEA-COM connector of the "Y" cable. Re-connect your Fishfinder  
accessories to the ACCY-COM connector of the "Y" cable.  
3. Power up the Fishfinder Fishing System (see your Fishfinder Operation  
Manual for details).  
4. When the Fishfinder detects the NMEA input from the GPS Receiver, the  
Combo, Track and Bird's Eye Views will be added automatically to the  
VIEW key function. A Navigation menu tab and the Navigation X-Press™  
menu will also be added automatically to the Menu system.

5. The Fishfinder Control Head outputs NMEA signals through the "pigtail"  
cable attached to the end of the GPS receiver cable for connection to  
devices such as autopilots. Connect the NMEA Out (White Wire) of the  
cable to the NMEA In of the device you are connecting to your Fishfinder.  
The pinouts of this cable are as follows:  
• Red Wire, +12V (output voltage only)  
• Black Wire, Ground  
• White Wire, NMEA Out.  
CAUTION! Please use caution before connecting the red +12V wire to any  
other NMEA device. This is an output voltage provided by the Fishfinder unit  
and receiver and should only be connected to those NMEA devices that need  
a 12 volt input.

1. If you have a pre-existing stem mount, skip to step 2.  
If you need to mount the antenna pole (stem),  
determine the best location, preplan and test the  
cable routing to your Fishfinder unit before any  
drilling or cutting of your boat surfaces, then route  
the 20’ (6 m) cable to the desired mounting location.  
Mark the location and drill a 3/4” (19 mm) hole for the  
cable and cable connector. If you have purchased  
hardware to stem mount your GPS receiver, follow  
the instructions included with that hardware to

Use your Fishfinder to establish waypoints at areas of interest and to navigate  
to those waypoints via a route (representing 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 Fishing System can store up to 750 waypoints.

Routes link two or more waypoints together to create a path for navigation, and  
are used in trip planning. 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.  
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 2000 trackpoints displayed). You can clear the Current  
Trackorsaveitatanytime. YourFishingSystemcanstoreupto10savedtracks, each  
containing 2000 trackpoints. The current track represents your actual path so far.

• Simulator  
• System Status  
• PC Connect  
(use with PC Connect Cable).  
See the following paragraphs for more information about each of these choices.  
Normal Operation  
Use Normal operation for on the water operation with a transducer connected. In  
addition, your Fishing System 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 Fishing  
System can be used on the water.  
Exit Normal operation by powering your Fishing System off.  
 
18  
Simulator  
Use the Simulator to learn how to use your  
Fishing System before taking your boat on the  
water. The Simulator is a very powerful tool that  
simulates on the water operation, providing a  
randomly-updated display. We recommend  
going through this manual while using the  
Simulator, since all of the menus function and  
affect the display the way they actually do when  
in Normal operation.  
Simulator, Shown with Optional  
WeatherSense® Accessory  
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 Fishing System  
enter Simulator automatically (as it will if a transducer is not connected and you do  
nothing during power up). Manually selecting Simulator from the Start-Up Options  
menu allows you to pre-configure your Fishing System for on the water operation. Any  
menu changes you make will be saved for later use.  
A message will appear on the display periodically to remind you that you are using

Receiver.  
Accessory Test Screen  
GPS Diagnostic View  
GPS Diagnostic View shows a sky chart and numerical data from the GPS  
receiver. The sky chart shows the location of each visible GPS satellite with its  
satellite number and a signal strength bar. A dark gray bar indicates that the  
satellite is being used to determine your current position. A light gray bar  
indicates that the satellite is being monitored, but is not yet being used.  
NOTE: The GPS Diagnostic View only appears if the GPS Receiver is connected.  
This view also reports the current position, local time and date, and other  
numeric information. The current GPS Fix Type is reported as No Fix, 2D Fix, 3D  
Fix, or Enhanced. An Enhanced fix has been augmented using information from  
 
20  
WAAS, EGNOS, or MSAS. A 3D or Enhanced Fix is required for navigation.  
HDOP (the Horizontal Dilution of Precision) is a GPS system parameter which  
depends on the current satellite configuration. HDOP is used to calculate the  
Estimated Position Error.

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.  
Fishing System Doesn’t Power Up  
If your Fishing System 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 Fishing System 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, and  
• 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.  
Fishing System Defaults to Simulator with a Transducer Attached  
A connected and functioning transducer will cause the newly-started Fishing  
System to go into Normal operating mode automatically. If, when you power up  
the Fishing System, 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 Fishing System,  
check to make sure that the transducer cable is securely connected to the  
Fishing System. Reconnect if necessary, and power up the Fishing System  
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  
Thereareseveralmainconditionsorsourcesofpossibleinterferencethatmaycause  
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  
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.  
The control head loses  
power at high speeds.  
The transducer position may need to be adjusted. A mix of  
air and water flowing around the transducer (cavitation)  
maybeinterferingwiththeinterpretationofsonardata. See  
your Installation Guide for suggestions on adjusting the  
transducer position.  
When the boat moves  
at higher speeds, the  
bottom disappears or  
suddenly weakens, or  
the display contains  
gaps.  
Electrical noise from the boat’s engine may be interfering  
with sonar reception. See Finding the Cause of Noise for  
more information.  
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,  
eitherbecauseitismountedinsideahullthatistoothickfor  
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.  
There are no fish  
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.  
Electrical noise from the boat’s engine may be  
interfering with sonar reception. See Finding the Cause  
of Noise for more information.  
 
50  
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  
Isolation  
Other electronic devices  
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.  
The boat’s engine  
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.  
Cavitation from the boat’s  
propeller  
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.

GPS & Navigation Glossary  
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.  
 
53  
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.  
 
54  
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  
 
55  
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  
 
56  
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 desired line of travel between two  
waypoints, and 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, 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.
