Congratulations!
You have purchased one of the finest 12-channel GPS receiv ers Eagle™
has ever made. With its high contrast LCD screen, easy to use menus,
and outstanding performance, we think you’ll be happy with your Eagle
Explorer™ for many years.
GPS works from satellites that transmit information to the world at very
high frequencies. One disadvantage to this frequency is that it’s “line-ofsight”. In other words, the signals don’t bounce around like your local
radio or television. If you don’t have a clear view of the sky, or if you’re
inside a building (such as a house), the unit probably won’t be able to
pick up the signals from the satellites. This is common among all GPS
receivers.
Like most GPS receivers, your Eagle Explorer doesn’t have a compass
or any other navigation aid built into it. It relies solely on the signals from
the satellites to determine its position. Speed, direction of travel, and
distance are all calculated from position information. Therefore, in order
for it to determine the direction you’re tra velling, you m ust be moving, and
the faster - the better. This is not to say the unit won’t work at walking
speeds - it will. But the faster you travel, the easier it is for the unit to
determine your direction.
Another factor that influences the GPS’ position and navigation capabilities is called selective availability or S/A. This is small errors purposefully
injected into the transmitted signal from the satellites. The government
does this to degrade the system’s accur acy to civilian and foreign users.
Even with S/A, GPS is the most accurate navigation system e v er invented
on such a large scale. The Government’s accuracy specification is 100
meters horizontally and 150 meters vertically 95% of the time. In other
words, the position shown on your Eagle Explorer could be up to 100
meters in any direction from your actual position, and the altitude could
be plus or minus 150 meters from what’s shown on the screen, 95% of
the time.
There are two ways around the S/A problem. One is to have the government simply turn it off. In fact, there is gr owing pressure on them to do
that, but it’s not likely to happen anytime soon. The other method is to
purchase a DGPS receiver and connect it to y our Eagle Explorer . A DGPS
receiver (commonly called a beacon receiver), picks up correction signals broadcast from ground stations. The Eagle Explorer takes these
corrections and applies them to the position and altitude screens, giving
you much better accuracy.
5
Even with S/A on, and without a DGPS receiver, your Eagle Explorer
gives you outstanding position and navigation information. Most people
are amazed when they actually use a GPS receiver and see what it does .
Please sit down with the unit and this manual and familiarize yourself
with them before using the Eagle Explorer in the “real world”. A simulator
is built in, which lets you practice.
INSTALLATION
The Explorer will operate from four AA batterie s, one DuraCell® rechargeable battery , or from 6 to 16 volts DC . An optional cigarette lighter adapter
is available to plug into a car or boat’s electrical system. The Explorer
automatically switches to external power when it’s plugged into the unit.
If, for an y reason, the external power f ails, the unit will automatically switch
to the batteries.
The Explorer does not require batteries when the external power is in
use, however they make a good backup in case of power failure.
BATTERY INSTALLATION
For battery operation, the Explorer requires four AA batteries or the optional DuraCell® rechargeable battery . We recommend DuraCell® alkaline
batteries, but other brands will work. You can also use rechargeable nicad batteries (however, they won’t last as long as standard alkalines).
Rechargeable alkaline batteries such as RayOVac® Renewals® will also
work.
Do not use heavy-duty batteries or
any battery type other than the ones
listed above. Do not mix different
types of batteries. (For example,
don’t use both alkaline and ni-cad
batteries at the same time.)
To install the batteries, first turn the
over on its back. Now push the two
tabs to the left and raise the battery
cover as shown below. The bottom
part of the case holds the batteries.
6
There are “+” and “-” marks on a decal at the bottom of the battery compartment. Place the batteries into the compartment according to the
marks and replace the battery cover. The Explorer is now ready for use.
EXTERNAL POWER
Instead of batteries, the Explorer can operate on 6 to 16 volts DC from
an external power source. To use external power, an adapter cable must
be purchased (model CA-2) that will plug into your vehicle’s cigarette
lighter. To use this cable, simply plug one end into the connector on the
Explorer and the other end into the cigarette lighter.
KEYBOARD
The keyboard has twelve keys. The arrow keys are tied to most of the
features, letting you easily move the plotter’s cursor, navigate through
the menus, make selections from menus, and other tasks.
MODE
MENU
ZOUT ZIN ENT PWR
WPT
EXIT
The WPT key lets you create , s av e, and recall wa ypoints and routes. The
MODE key s witches the unit between the three major displa ys: windo w s,
navigation, and plotter. To select different features, or to modify functions, press the MENU ke y . The Z-IN and Z-OUT ke ys zoom-in and zoomout your view on the plotter screen. The ENT and EXIT keys let you enter
or erase selections. The PWR key turns both the Eagle Explorer and it’s
lights on and off.
Note: T o pre vent an accidental power shutdown, you m ust hold the PWR
key down for a few seconds in order to turn the unit off.

OPERATION
Turning Power On
To tur n the Eagle Explorer on, simply press the
PWR key. A screen similar to the one at right appears. Read the message on the screen, then
press the EXIT key to erase it. The Explorer is
now ready for use.
MENUS
Most of the Eagle Explorer’s adjustments and f eatures are found on “men us”. Pressing the MENU
key lets you vie w the menus. Different men u items
are added to the basic list, depending on which
mode (plotter, na vigation, or windows) the unit is
in. This gives you the features that are specific to
the mode you are in, but also has items that are
used on all modes.
Pressing the up or down arrow keys moves the
black box to highlight different menus on the list.
Pressing the right arrow key selects the highlighted menu item.
To erase a menu, press the EXIT key.
Finding Y our Position
Cold Start
When the Eagle Explorer is turned on for the very first time, it doesn’t
know where it is, nor what the local time or date is. I f you tell it your
position, time, and date, the unit will tak e much less time to lock-on to the
satellites and give you a fix or position.
However, if you don’t want to push buttons at this time, that’s fine. The
Eagle Explorer will lock onto the satellites and giv e y ou a position without
any input from you. This is called a “cold-start” . It simply means that the
unit is searching without help for the satellites that are in orbit. A coldstart can take over two minutes to acquire enough satellite data to determine your position, although it typically takes less time than that.
8
To use your Explorer , first make certain you have a clear view of the sky,
free from any obstructions such as trees or buildings. Also, don’t try to
use it under a carpor t , covered boat dock, or inside a building. Turn the
power on, press the EXIT key to erase the opening message and watch
the display.
As you wait for the Eagle Explorer to find your
position, you’ll see numbers flashing on the display. Anytime y ou see flashing numbers , it means
the Eagle Explorer does not have a position! Do
not rely on any data that is flashing! Once the
Explorer locks on to the satellites and finds your
position, it shows a “Position Acquired” message
on the screen. It also stores the satellite data in
its memory. The next time you use the unit, it
should take much less time to lock on.
That’s all you have to do to find your position.
Your local time display may not be correct when
the cold start method is used. See the initialization section for details on
changing the time.
Finding Y our Position
Initialization
A cold-start as descr ibed above can take over two minutes to find your
position. A faster method is to initialize the Eagle Explorer manually. To
do this, first press the PWR key. Next, read the message on the screen
and press the EXIT key to erase it. Now press the MENU key.
Press the up or down arrow keys until the “GPS
SETUP” menu is highlighted. No w press the right
arrow key. Next, using the down arrow key, highlight the “INIT GPS” (initialize GPS) menu, then
press the right arrow key. The screen shown at
right appears.
This is the GPS initialization screen. The position, altitude, time, and date the Eagle Explorer
is currently using to find the satellites is shown at
the bottom of this screen. Changing these values
to your local position and time will speed the position lock.
9
To change the position, press the right arrow key
while the “LAT/LON EDIT” box is highlighted. The
screen shown at right appears.
If your latitude is south, press the up or down arrow key to change it. If it is north, press the right
arrow key to mo ve the change box to the first n umber in the latitude. No w press the up arrow k ey to
increase the number or the down arrow key to
decrease it. Once the first number in the latitude
is set, press the right arrow key once to move to
the next number in the latitude.
Keep pressing the arrow keys until the latitude and longitude are set to
your local position. (Note: This position does not have to be very accurate. If you can get it within one degree of y our actual position, that will be
fine.) When it’s set, press the ENT key. The Explorer accepts your entr y
and returns to the GPS setup menu.
Now change the local time and date (if they’re incorrect) on this screen.
(Don’t worry about altitude.) When everything is acceptable, press the
EXIT key repeatedly to return to a mode screen. The Explorer will instantly use the data you entered to find the satellites in the sky. (The unit
knows which satellites will be av ailable at the position, date , and time you
entered. Therefore, it will only look for those satellites , making the search
time much shorter than a cold start which looks for all of the satellites
until it finds three.)
Once the Eagle Explorer finds and locks on to three satellites, it stops
flashing the numbers on the display. (Note: Altitude will still flash until the
unit locks on to the fourth satellite. It takes four satellites to determine
altitude.)
IMPORTANT!
If the data shown in digital numbers on any screen is flashing, it means
that data is invalid. DO NOT RELY ON ANY NUMBERS THAT ARE
FLASHING! Usually, this happens when the Eagle Explorer has lost
its lock on the satellites. The data that is flashing was the last known
when the unit lost its navigational capability.
DO NOT NAVIGATE WITH THIS UNIT UNTIL THE DATA STOPS
FLASHING!
10
POSITION/NAVIGATION DISPLAYS
The Eagle Explorer has navigation, plotter, and windows group modes.
These screens were designed to show data that is used most often. The
three default screens are shown below.
NA V-1 PLO T-1 GROUP A
To change screens, simply press the MODE key.
A screen similar to the one at right appears. No w
press the up or down arrow ke ys to change modes.
(The windows displa y is shown as "GRP" (groups).
For example, Group A is the first windows group
on the MODE menu.) Press the right arrow key to
see more screens on each mode. When the desired screen appears, press the EXIT key to clear
the menu.
Note: For a list of abbreviations used on the displays, see the back of this manual.
Navigation Screens
There are two na vigation screens. Na v screen number one shows a graphical view of your trip , the other screen sho ws all na vigation details in large
digital numbers. You can customize the na vigation screens to show different data than the ones chosen by Eagle. See the “Customize Screen”
section for more details.
11
Nav Screen #1
This screen is dominated by a compass rose (See
the screen at right.) Your position is in the center
of the circle, designated by an arrow that always
points straight up. Your trac k (direction of trav el) is
indicated by an arrow pointing down toward the
compass rose at the top center of the screen. Your
track in digital numbers is also shown to the right
of the arrow. On the screen shown at right, the
track is 167°. The line extending behind the arrow
in the center shows your track history, or path
you’ve travelled.
Your speed over ground or Ground Speed (GS)
shows in the digital box in the bottom left corner
of the screen. The screen looks lik e the one above
when you’re not navigating to a waypoint. (See
page 28 for information on waypoint navigation.)
If you navigate to a waypoint, the screen looks
like the one at right.
The bearing to the destination waypoint is shown
in the upper left corner of the screen. Bearing is
also shown by the large arrow pointing up to the
compass. The bearing is 176° on the screen at
right.
NAV-1
The lines on either side of the present position
arrow show the cross track error range. In other
words, (using the screen abo ve as an example) if
the arrow crosses the line on either side, y ou are
.10 miles to the left or right of the desired course.
A circle depicting your destination appears on the
screen as you approach the waypoint as shown
on the screen at right.
The digital box es on the bottom of the screen show
your distance to go to the destination (DIS), g round
speed (GS), cross track error (XTK), and course
(CRS).
Course (CRS) is the bearing from your starting
location to your destination. (Remember, course
12
has nothing to do with your present position, except for your starting
location.) It’s shown as a dotted line on the NAV 1 display. This is shown
as a reminder so that if you deviate from your original course, you can
easily return to it. (A “course” is a proposed path over the ground. A
“track” is your actual path over ground.)
Nav Screen #2
This navigation screen shows na vigation information in large digital numbers. To view this screen,
press the MODE key, then press the up arrow
key until the “NA V 1” label is highlighted. No w press
the right arrow key. A screen similar to the one at
right appears. Press the EXIT key to erase the
mode menu.
This screen is composed of eight digital display
boxes, showing your track (TRK), and ground
speed (GS). The other box es show navigation data
when a waypoint is recalled, including bearing to
the waypoint (BRG), course (CRS), distance to
waypoint (DIS), estimated time en route (ETE),
and cross track error (XTK) along with a CDI. See below for more information on the CDI.
Course Deviation Indicator (CDI)
The CDI shows your distance to the left or right of
the desired course. You must recall a waypoint or
run a route to use the CDI. The vertical line in the
center of the box shows the direction to the destination. For example, if you’re travelling straight towards the destination, the line sta ys in the center of
the CDI. If you turn to the right, the line moves to the left, showing that
the destination is to your left.The CDI’s range shows in the upper left
corner. The default is 0.25 mile. The dots at the far right and left side of
the CDI represent 0.25 mile. If the line is on either of these dots, then y ou
are 0.25 miles off course. Remember, if the bar moves to the left, then
you are too far to the
right
of the desired course line, and vice-versa. On
the indicator shown above, we are almost 0.2 mile to the left of the desired course. You can adjust the CDI’s range through the “ALARMS/CDI”
menu .
Using the CDI with the plotter helps you visualize your position in relation
to the course. The CDI is on several of the Explorer’s windows.
13
Plotter
The plotter lets you see your course and track
from a “birds-eye” view. If you’ve recalled a waypoint, the plotter show your starting location,
present position, and destination. However, you
don’t have to recall a waypoint to use the plotter.
To use the plotter, simply press the MODE key,
then press the up or down arrow keys until the
“Plot” label is highlighted. Press the EXIT key to
erase the mode menu. A screen similar to the one
at right appears. This is plot-1. The diamond flashing in the center of the screen is your present
position. The solid line extending from the diamond is your track, or path
you’ve travelled. The plotter’s range is shown in the lower left corner of
the screen. In this example, the plotter’s range is two miles from the left
edge of the screen to the right.
There are two different plotter screens available. Plot screen number 1
shows by default. Your current position displa ys at the center of the screen
as a cross surrounded by a flashing diamond.
To view the other plotter screen, press the MODE
key. Press the up or down arrow key to move the
black bo x to the "PLOT" label. Now press the right
arrow or left arrow key to select plot-2. This screen
(as shown at right) has navigation data displa yed
at the bottom of the screen in digital numbers.
This data is active whene ver you’ve recalled a way point. Press the EXIT key to erase the mode menu .
This screen shows bearing to waypoint (BRG),
distance to waypoint (DIS), ground speed (GS),
and track (TRK).
Use the Z-IN and Z-OUT keys to enlarge or reduce the plotter area. This
changes the plotter’s r ange. The available ranges are: 0.1, 0.15, 0.2, 0.3,
0.4, 0.6, 0.8, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 15, 20, 30, 40, 60, 80, 100,150,
200, 300, 400, 600, 800, 1000, 1500, and 2000 miles.
Cursor
Pressing an arrow key while the plotter is on shows two dotted lines that
intersect at your present position. These dotted lines are called a “cursor”
and have a variety of uses.
14
You can move the cursor around the display by
pressing the arrow ke ys in the direction you want
it to move. This lets you view different areas of
the plotter , aw ay from your present position. When
it’ s turned on, the zoom-in and zoom-out ke ys work
from the cursor’s position - not the present position, so you can zoom in on any detail, anywhere
while navigating. The latitude/longitude of the cursor shows in the box at the top of the plot-1 screen
whenever the cursor is activated. The cursor is
also used to place and erase icons and wa ypoints.
Press the EXIT key to erase the cursor.
PLOTTER OPTIONS
The Eagle Explorer lets you customize the plotter
using the “Plotter Options” menu. To use this menu,
first press the MENU key, then use the up or down
arrow ke ys to highlight the “Plotter Options” label.
Finally, press the right arrow key. The screen
shown at right appears.
Plotter Orientation
Normally, the Eagle Explorer shows the plotter
with north always at the top of the screen. Thi s is
the way most maps and charts are printed on
paper. This is fine if you’re always travelling due
north. Wa ypoints y ou see to y our left corresponds
to the left side of the plotter, to your right shows on the right side of the
plotter, and so on.
However, if you travel any other direction, the plotter doesn’t line up with
your view of the world.
To correct this problem, the Eagle Explorer has a track-up mode that
rotates the plotter as you turn. Thus, what you see on the left side of the
screen should always be to your left, and so on. It also has a course-up
mode that keeps the plotter at the same orientation as your initial bearing
to the waypoint.
15
In the examples shown belo w , we're travelling southeast (about 150° magnetic). In the north-up view, the present position indicator appears to
move to wards the lo wer right corner of the screen. The anchor icon shown
on the right side of the screen is actually on our left. North is always at
the top center of this screen.
NORTH-UP MODE COURSE-UP MODE
TRACK-UP MODE
In the track-up view, the present position symbol (which has changed to
an arrow) moves straight towards the top of the display. As you can see,
the anchor icon is now shown in its proper orientation - to our right. A "N"
shows to help you see which direction is north when the tr ack-up mode is
on. Remember, in the track-up mode, the screen rotates as you change
direction. It always keeps your direction of travel (track) heading towards
the top of the screen.
In the course-up mode, the screen is locked into your original bearing to
the recalled waypoint, regardless of your track.
To select the desired mode, highlight the “ROTATE” label on the “Plotter
Options” menu, then press the left or right arrow keys until the desired
mode appears. Press the EXIT key to leave this menu
Clear Current Plot Trail
The line extending from the present position diamond on the plotter shows
the path you’v e t aken, This is the plot tr ail. To erase the plot trail, highlight
the “ClearTrail” label on the Plotter Options menu, then press the r ight
arrow ke y. A message bo x appears, asking y ou if you really want to erase
the plot trail. Follow the directions on this message box. The Explorer
returns to the plotter screen with the plot trail erased from the screen.
16
Grid Lines
The Eagle Explorer can place grid lines on the
plotter to help you see your position, or the position of waypoints and icons.
To do this, highlight the “Grid” label on the “Plotter
Options” menu, then press the right arrow key to
turn them on. Press the EXIT key to exit this menu.
A plotter screen similar to the one at right appears. The grid lines appear as vertical and horizontal dashed lines.
GRID LINES
Plotter Update
The plotter places a dot on your trail as you move. It determines when to
place a dot depending on either time or distance. By default, it places a
dot every three seconds.
To change the update method from time to distance, highlight the “Update By” label, then press the right arrow key. This moves the label from
“TIME” to “DIST”.
If you want to change the update time or distance , simply highlight either
the “UPDT RATE” to change the update time or the “UPDT DIST” to
change the update distance, then press the left or right arrow keys until
the desired setting appears. Press the EXIT ke y to erase the plotter menu.
ICONS
The Eagle Explorer has fifteen symbols or “icons” a vailable. These icons
can be placed anywhere on the plotter screens. These can be used to
mark fishing or hunting spots, boat ramps, rest stops, or whatever. You
can place an icon at your present position, or at
the cursor location.
Place Icon - Present Position
To place an icon at your present position, simply
press the ENT key. The screen shown at right
appears. Use the arrow keys to move the black
box to the desired icon. Now press the ENT key.
The plotter screen appears with the icon you selected placed at your position when you first
pressed the ENT key, not your present position.
17
Place Icon - Cursor Location
To place an icon at cursor's location, first use the arrow keys to mov e the
cursor to the position that you want to place the icon. Next, press the
ENT key. Now select the desired icon using the arrow keys. When it's
selected, press the ENT key again. The plotter screen reappears with the
icon at the cursor's location. Press the EXIT key to erase the cursor. On
the screens shown below, the house icon was selected and placed at the
cursor location.
PLACE CURSOR ICON ON PLOTTER
PRESS ENT KEY
AND SELECT ICON
Erase Icons
To erase an icon from the screen, first press the
MENU key, then select the “WPT/Icon Options”
menu. A screen similar to the one at right appears.
There are three methods used to erase icons from
the screen. You can delete all of the icons, regardless of their position on the display, delete all
of the icons of a certain type, or selectively eras e
individual icons. You can also simply turn all of
the icons off without erasing them.
To turn all of the icons off, without erasing them,
highlight the “ICONS OFF ON” label, then press
the left arrow ke y . To erase all of the icons, highlight the “DEL ALL ICONS”
menu, then press the right arrow key. A message appears, asking you if
you want to delete all icons . Press the right arrow k ey to erase them. T he
unit returns to the plotter screen with all icons deleted.
18
To remove only icons of a certain type, highlight
the “DEL ICON TYPE” label. Press the right arrow key. The icon selection menu appears. Use
the arrow keys to highlight the icon style that you
wish to erase. Press the ENT key when you’re
ready to erase the icons. A message appears,
asking you if you want to delete the icons of that
type. Press the left arrow key to erase them. The
unit returns to the plotter screen with all icons of
the type you selected erased.
To remo ve only certain icons, highlight the “DEL
FROM PLOTTER” label. Press the right arrow

Satellite Information Screen (Group O)
This screen shows technical information about the
status of the GPS receiver. The receiv er has twelve
channels. Data for each channel is shown as bar
graphs on the right side of the display. Every satellite in the constellation has a number assigned
to it, called the PRN. The bar graph is beside each
satellite’s n umber. The higher the bar on the graph,
the better the signal is being received from the
satellite.
Each satellite is also shown on the circular graph
at the top of the screen. This shows you not only
which satellites are in your area, but also their direction from your position, and their elevation (distance above the horizon.) The small inner
circle represents 45° above the horizon and the large outer circle represents the horizon. A satellite is straight above you when it is at the intersection of the horizontal and vertical lines that pass through the circles.
The FIX number in the upper right corner of the screen show the quality
of fix. If the FIX is 9, then it's the best y ou can get. A FIX of 1 is the worst.

WAYPOINTS
The Eagle Explorer gives you the capability of creating your own database of locations, called “wa ypoints”. You can sa ve y our present position,
cursor position, or enter a latitude/longitude and save it as a waypoint.
The Eagle Explorer can store up to 250 waypoints.
Saving Your Present Position as a Waypoint
(Quick Save Method)
To save your present position, simply press the
WPT key
twice
. The Eagle Explorer puts your current position into the first available wa ypoint number on the list. A message appears on the displa y
telling you the waypoint number it just used. This
also momentarily places you in the database
menu. Anytime a database menu is showing, simply press the WPT k ey once and the unit will store
your present position in the waypoint list.
Every time you save a w aypoint, the date and time
are logged along with the position data. It’s position is also placed on the plotter as shown above.
In this case, wa ypoint number one was assigned
when we quick-saved our position.
Saving The Cursor Position as a Waypoint
When the cursor is showing on the plotter and
you press the WPT ke y twice, the Eagle Explorer
puts the
cursor’s
position into the first available
waypoint number. In the example screen shown
at right, the cursor is placed at the desired location. Pressing the WPT twice causes waypoint
number two to be placed at the cursor’ s crosshairs.
(See the screen at the top of the next page.) A
message appears on the display telling you the
23
wa ypoint number it just used. Wait a fe w seconds
and the menu will clear automatically. Press the
EXIT key to erase the cursor.
Saving Your Present Position as a Waypoint
(Select Number Method)
The method shown above doesn’t let y ou choose
the waypoint number. You can pick the waypoint
number, then save your present position. To do
this, first press the WPT key once. A screen similar to the one at right appears.
Now press the up arrow key once. This is the
waypoint number selection menu. Press the left
or right arrow keys until the wa ypoint number appears that you wish to store your present position. In this example, we’ re going to store a position as waypoint number 6.
Now press the down arrow key until the “WPT Options” label is highlighted. Press the right arrow key. A screen similar to the one shown at right appears.
Highlight the “SaveWPT As” label (shown at the
bottom of the menu) and press the right arrow
key when you’re at the location you wish to save.
This saves your present position under the waypoint number you selected on the first page.
Saving Cursor Position as a Waypoint
(Select Number Method)
To save the cursor position under a specific wa ypoint number, first position the cursor at the de-
24
sired position. Then f ollo w the previous instructions for sa ving your present
position as a waypoint using the select number method. Remember, the
method
of saving your present position and the cursor’s position is iden-
tical.
Edit Lat/Lon
The Eagle Explorer lets you enter any latitude/
longitude using the keyboard and save it under
any wa ypoint number , from 1 to 250. You can also
change any wa ypoint’ s position using this method.
To do this, first select the waypoint number that
you want to save a position under from the waypoint menu. In this example, we’ll use waypoint
number 10. Next, highlight the “Options” men u and
press the right arrow key. Now highlight the “Edit
Lat/Lon” menu and press the right arrow key. The
screen shown at right appears. Using the left and
right arrow keys , highlight each number in the position and change it using the up and down arrow
keys. When you’re ready to save this position and return to the waypoint
screen, press the ENT key. The location y ou entered shows at the bottom
of the screen under the waypoint number you selected. Note: You can
also use this method to change the position of an existing waypoint.
WAYPOINT NAMES
The Explorer automatically assigns the waypoint n umber as a name when
the waypoint position is sa v ed. You can find a wa ypoint by highlighting the
name on the waypoint menu as shown below left. Now press the right
arrow k ey. The screen shown below right appears. Use the arrow keys to
scroll through the saved waypoints. Only waypoints that have a position
will show using this method.
25
Edit Name
The Eagle Explorer also lets you assign a name
to each waypoint. The name can hav e up to eight
characters. To name a waypoint, first select the
waypoint number that you wish to name. Now
highlight the “WPT Options” label and press the
right arrow ke y . Finally, highlight the “EDIT NAME”
label and press the right arrow ke y . A screen similar to the one at right appears.
Press the up or down arrow keys to select the
first letter in the name. Press the right arrow key
to move the black box to the next position in the
name. Repeat this sequence until you’ve entered all of the letters in the
waypoint name. Press the ENT key to accept this name, the WPT key to
erase all characters in the name, or the EXIT key to leave this screen
without saving any changes.
MOVE A WAYPOINT
You can move all info rmation from one waypoint
number to another. In this example, we’ll move
all of the information in waypoint number 10 to
wa ypoint number 20. T o do this , highlight the waypoint options label on the waypoint screen and
press the right arrow ke y . Now highlight the “Move
WPT” label. Press the right arrow key. The screen

the right arrow key until the desired w aypoint number shows in the box. When everything on this
page is correct, press the ENT key.
Note:The names in the “F rom” and “T o” boxes are
not the waypoint numbers - they are the waypoint
names. When a w aypoint is mov ed from one number to another, the new waypoint number gets
the old waypoint name. For example, moving
wa ypoint number 2 to waypoint n umber 5 deposits the name “WPT 2” in waypoint 5’s name field.
26
DISTANCE BETWEEN WAYPOINTS
The Eagle Explorer can easily give you the distance between two user waypoints. To do this,
first press the WPT key, highlight the “Options”

plotter, or windows screen and shows navigation
information to the selected location.
In this example, we recalled waypoint number 1.
Switching to a plotter screen (shown at right)
shows our starting location “S”, the recalled waypoint “1”, and our present position.
Navigating to a cursor location
The Eagle Explorer lets you navigation to a location without storing it in
the waypoint database by using the plotter and cursor. To do this, first
switch to the plotter screen. N ow mov e the cursor to the location that you
want to navigate to . Next, press the MENU key. A new menu appears on
the list: “Go To Cursor”. Press the right arrow key. The Eagle Explorer
shows nav data to the cursor location (shown as “D” on the plotter). See
the screens at the top of the next page.
32
Navigating to a Waypoint using the Plotter
The unique “birds-eye” v iew used by the plotter gives y ou an easy w a y to
navigate to a waypoint. On the plotter screen shown on the previous
page, the diamond with a cross in it is your present position. The box with
the “ S” in it was your star ting location when you recalled the waypoint.
The dotted line is called a track line and is the shortest path from the
starting location to the destination. The number “1 ” is waypoint number
one, which is the recalled waypoint and the destination. The “D” on the
plotter screen at the top of this page is the cursor destination, when the
cursor position is used as a destination. If you follow the track line, you’ll
reach the destination, covering the shortest distance in the least time.
CAUTION!
The Eagle Explorer does NOT take land features, altitudes, restricted or
prohibited areas, or any other feature into account when it projects the
track line on the screen. Therefore, you must use care when navigating
on the track line and avoid any object that may be in your path to the
destination.

NMEA / DGPS
The Eagle Explorer transmits data through the data port in the back of
the unit using NMEA 0183 format, v ersion 1.5 or 2.0. This data is used by
other electronic devices such as marine autopilots for position and steering information.
DGPS on the other hand, is a data input. DGPS is an acronym for Differential Global P ositioning System. Currently, it relies on a system of groundbased transmitters that send correction signals to small DGPS receivers .
DGPS gives you a more accurate position than is otherwise possible.
All wiring connections to the Eagle Explorer are made to it’s power cab le.
See the sample wiring diagrams on the next page f or general wiring procedures. Read y our other product’ s owner’ s m anual f or more wiring information.

communication settings.
Configure NMEA Output
Highlight the “Configure NMEA Output” menu,
then press the right arrow key. A screen similar to
the one at right appears.
NMEA 0183 Version
There are two versions of the NMEA data, 1.5
and 2.0. If your other equipment requires 2.0,
press the right arrow key to select it.
GLL Sentences - RMC/RMB Sentences - APB
Sentences
Some equipment requires different sentence. The
Eagle Explorer’s default setting for these sentences is on. In other w ords, it automatically sends
these sentences when NMEA is turned on. To turn
any of these off, move the black box to the desired menu and press the left arrow key. Press the EXIT k ey when everything on this screen is the way you want it.
DGPS
The Eagle Explorer will recognize Starlink® and Magnavox® DGPS receivers. If you have either one of these receivers, simply highlight the
“Starlink DGPS” or “Magnavox DGPS” on the NMEA / DGPS menu and
press the right arrow key to turn it on. (Note: If you have a Magnavox
DGPS receiver connected, the Eagle Explorer can’t send NMEA data.)

arrow key to quit.
If you restore the unit to the f actory settings, all options such as contrast,
alarm s, and other system choices are retur ned to their default values.
However, no waypoints, routes, or icons are erased.
RESET GROUPS

SYSTEM INFO
The system information screen shows the release
date and the version number of the code stored
inside the Eagle Explorer. To view this screen, highlight the “System Inf o” label on the “System Setup”
menu. Now press the right arrow key. A screen
similar to the one at right appears. Press the EXIT
key when you’re finished reading this screen.
GPS SETUP
The GPS Setup menu has sub-menus that affect
the GPS receiver . From these menus you can set
the update rate, initialize the GPS receiver, do a
self-test on the receiver, and do a cold-start. (Note: The “Initialize GPS
receiver” is covered in the “Finding Your Position” section in the front of
this manual.
To view these menu items, press the MENU key,
then highlight the “GPS Setup” menu. Press the
right arrow key. The screen at right appears.
GPS Cold Start
When the Eagle Explorer is turned on for the first
time “out of the box”, it automatically sends a “coldstart” message to the GPS receiver. You can also
send a cold start message to the receiver at any
time.
If the unit can’t lock on to the satellites using the
data you’v e given it, or if it has trouble finding the
satellites, perhaps it is using the wrong data. This can happen if you’ve
entered the wrong data by accident when initializing the receiver. For
example, if you entered east longitude instead of w est. Or if you’v e mov ed
a long distance with the unit turned off.
To send a cold star t message to the receiver, highlight the “GPS Cold
Start” label, then press the right arrow key. A message appears, asking
you if you really want to do a cold start. Follow the instr uctions on this
message page.
The unit will begin searching for the satellites. It can take as long as 5
minutes for it to lock on to the necessary satellites. Remember, when it
does, your local time and possibly date can be wrong. Use the method
shown in the initialization section at the front of this manual to change
39
them, if needed. Once this is done, an internal clock will keep the correct
time, even when the unit is turned off. The GPS system updates this
clock when the unit is locked on to the satellites.
DATUM
Maps and charts are based on a survey of the area that’s covered by the
map or chart. These surveys are called “Datums”. Maps that are created
using different datums will show the same latitude/longitude in slightly
different locations.
All datums are named. The GPS system is based
on the WGS-84 datum, which covers the entire
world. Other datums may also cover the entire
world, or just a small portion. By def ault, the Eagle
Explorer shows your position on the map using
the WGS-84 datum. However, it can show your
position using one of 189 different datums.
To change the datum, first press the MENU key,
then highlight the “GPS Setup” label and press
the right arrow ke y. Now highlight the “Select Datum” label. Finally, press the right arrow key again.
A screen similar to the one at right appears.
The WGS-84 label is highlighted. To change it, simply press the up or
down arrow k eys to highlight the desired datum, then press the ENT k ey.
This selects the datum and erases the select datum menu.
PCF (Position Correction Factor)
Another method used to make your display match a chart or map is
called “PCF” or Position Correction Factor. This unit gives you the capability to move or offset the position shown on the displa y to match one on
the chart. The unit will add this offset to all position and navigation displays at all times.
Remember, the position error on any radio navigation system is very
dynamic and the PCF offset should never be used in an attempt to cancel the error.
In general terms, PCF should only be used if your map indicates what
the possible error is. PCF should al wa ys be reset to zero when you’ re
finished with the chart.
For example, suppose you are stopped at a location that is accurately
40
marked on a chart. Your unit shows a longitude position that is .244 minutes east of the one on the chart and .047 minutes north latitude. Using
the PCF feature , you can mak e the Eagle Explorer match the chart you’re
using. If you move, the unit will continuously add the change to all position, navigation, and mapping displa ys. This makes it more closely match
the datum used by the chart. F or this reason, y ou should be careful when
entering the PCF offset. It’s saved in memory and doesn’t change when
the unit is turned off. However, resetting the unit does erase the PCF
offset.
To change the PCF offset, first press the MENU
key, then highlight the “GPS Setup” label and press
the right arrow key. Now highlight the “Set PCF
Offset” label. Finally, press the right arrow key
again. A screen similar to the one at right appears.
Now enter the correction for your location. Remember, this is the difference between the location shown on the present position display and
the position shown on the chart. In this example,
we entered 0 degrees, 0.047 minutes north latitude and 0 degrees, 0.244 minutes east longitude. That is the difference between the present
position shown by the Eagle Explorer and the one
on our chart.
After you’v e entered the latitude/longitude correction, press the ENT key to accept it. The Eagle
Explorer erases the PCF entry screen and returns
to the navigation or mapping screens with the correction factor applied.
POSITION PINNING
When using a GPS receiver at extremely low speeds, it can have trouble
determining your course over ground, or direction you’ re trav elling. This is
due in large part to SA, or selective availability. SA is small inaccuracies
purposefully put into the GPS satellite’s signal by the government. This
cause wide variations in the track display and other navigation displays
when using the unit at slow speeds.
41
If you’re using the Eagle Explorer without DGPS
and stop, the position pinning feature locks the
present position indicator on the plotter until you’v e
moved a short distance or exceed a very slow
speed. This prevents the “wandering” plot trail seen
when you’ re stopped with position pinning turned
off. This also affects the navigational displays.
The easiest way to see the effects of S/A is to
stand still with the Explorer turned on and watch
your plot trail with position pinning turned off. You’ll
see the present position change, speed increase
and decrease, and a random plot trail on the
plotter’s screen.
If you wish to turn the position pinning feature off, press the MENU key,
then highlight the “GPS Setup” label and press the right arrow key. No w
highlight the “Pinning” label. Finally, press the left arrow key.
ALARMS
The Eagle Explorer has several alarm s. You can set an arrival alar m to
flash a warning message when you cross a preset distance from a waypoint. For example, if you have the arrival alarm set to .1 mile, then the
alarm will flash a message when you come within .1 mile of the recalled
waypoint. The course deviation indicator alarm (CDI) can warns when
your track drifts too far to the right or left of the line to the waypoint. For
example, if the alarm is set to .1 mile, then the alarm flashes a message
if you drift .1 of a mile or more to the right or left of the line to the waypoint. The anchor alarm is triggered when you drift outside of a preset
radius. Again, using the .1 mile as an example, if you’re anchored and
your boat moves more than .1 of a mile, the alarm will flash a message.
To use any of these alarms, first press the MENU
key, then select the “SETUP ALARMS” menu. A
screen similar to the one shown at right appears.
Press the up or down arrow k ey to move the b lack
box to the desired alarm, then press the right arrow key to turn it on.
To adjust an alarm’s distance , move the blac k box
to the alarm’s “DIST” menu item, then press the
right or left arrow keys to increase or decrease
the alarm’s distance.
42
When you’re finished adjusting the alar m s, press the EXIT key to erase
this menu.
Impor tant Alarm Notes:
Anchor Alarm - Since civilian users don’t receive the accuracy given to
military users, the anchor alarm may be triggered even when you’re
sitting still. This typically happens when using small (less than .05 mile)
anchor alarm ranges. If you have a DGPS beacon receiver connected
to the Eagle Explorer, smaller ranges may be usable.
Arrival Alarm - If you set the arrival alarm’s distance to zero (0), and
you run a route (see the routes section), the Eagle Explorer may not
show navigation data to the next waypoint, once you arrive at the first
one. If you use the routes feature, never set the arrival alarm to zero.
MESSAGES
On the GPS Alarms menu are the position and DGPS message selections. When turned on, the position message appears for a few seconds
whenever the Eagle Explorer locks onto the satellites and shows a position. It also appears when the unit loses the lock onto the satellites and
cannot navigate. Pressing the EXIT key erases
these messages.
The DGPS message appears whenever the unit
begins or stops using DGPS data to help determine your position.
The default setting f or these messages is “on”. To
turn either message off, select the “Setup Alarms”
menu from the main menu, then move the black
box to the desired message and press the left
arrow ke y . Press the EXIT k ey to er ase this screen.
SIMULA TOR
A simulator is built into the Eagle Explorer that has several options. You
can use nearly all of the unit’s features - e ven save and recall waypoints.
This is useful for trip planning.
To use the simulator, press the MENU key, then press the up or dow n
arrow keys until the “Simulator Setup” menu is surrounded by the black
43
box. Now press the right arrow key. The screen
shown at right appears.
If you simply press the right arrow key, turning
the simulator on, the Eagle Explorer will start from
your present position and follow a trac k of 355° at
100 miles per hour.
To change either the track or speed, highlight the
one you want to change, then press the right or
left arrow key. When the numbers are correct,
press the EXIT key.
Starting Position
Normally , the starting position f or the simulator is
your present position. If you want to change the
starting position, highlight the “Set Starting Wa ypoint” label on the Simulator Setup menu, then
press the right arrow key. The screen shown at
right appears.
You can select any waypoint as the simulator’s
starting point. Select the starting point by pressing the right arrow key on the “WPT#” label until
the desired starting waypoint number appears.
Now highlight the “Star t At” label and press the
right arrow key. The Eagle Explorer returns to the
Simulator Setup menu using the waypoint you specified as the star ting
waypoint.
Use Arrow Keys to Steer
This option lets you change both the course and
speed on the screen as the simulator is running.
To do this, highlight the “Steer With Arrows” label
on the Simulator Setup screen, then press the
right arrow key. The screen shown at right appears. Use the up and down arrow keys to increase or decrease the speed. Use the right and
left arrow keys to change the track. Press the
EXIT key to erase these menus.
When you’re finished changing the tra ck and
speed, press the EXIT key to erase the menus.
44
To turn the simulator off , press the MENU k ey, then move the blac k bo x to
the “Simulator Setup” label. Finally, press the left arrow key.
Note: Your plot trail will be erased when you turn the simulator on or off.
BACKLIGHT
The Explorer’s display has lights that can be
turned on for night use. To turn the lights on, simply press the PWR key. To tur n them off, press
the PWR key again.
The Explorer automatically turns the lights off after
30 seconds to preserve the battery power. It will
do this even if the e xternal power is applied to the
unit.
The time delay is adjustable from 0 to 240 seconds. You can change this from the System Setup
menu. To do this, press the MENU key, then highlight the System Setup menu and press the right arrow key. Next, highlight the “Light Dly” (light delay) menu. Press the right arrow key to increase the time the lights are on, the left arrow key to decrease it. Press
the EXIT key to erase this menu.
