INTRODUCTION
The AccuNav Sport™ is a high quality, big screen handheld GPS receiver with performance that is second to
none in its class. Using menu features and raised softkey operation, the AccuNav Sport™ is also one of the
easiest to use products that Eagle has ever built. The
wide screen shows the navigation and plotter screens
with high resolution and detail. The display and keyboard are also lighted for night operation.
The electronics are sealed inside the welded, dry nitrogen filled case. This both waterproofs the unit and helps
prevent fogging on the display. The battery compartment has "O" ring seals to keep water penetration to a
minimum.

GPS - HOW IT WORKS
The Global Positioning System (GPS) is perhaps the
best approach to navigation that has ever been devised.
Conceived by the Department of Defense (DOD) and
the United States military, the GPS system is an answer
to their needs of 24 hour global positioning, 365 days a
year.
Basically, the system works by using a constellation of
satellites orbiting Earth 11,000 miles in space. There will
be 24 satellites in orbit when the system is fully operational. When all satellites are in place, at least four of
them will be in view nearly anywhere on Earth twentyfour hours a day. The GPS receiver requires at least
three satellites to give a “2D” fix. (A 2D fix is your position
in latitude/longitude. A 3D fix is your latitude/longitude
plus altitude.) When it locks on to at least four satellites,
it displays a 3D fix.
2
It takes three satellites to determine position.
As the receiver locks on to each satellite, it calculates
the distance from the satellite by measuring the length
of time it takes the radio signal to reach it. Each satellite
has an extremely accurate clock that tells the receiver
when the radio transmission started. The receiver compares that time against its own clock, thus it knows how
long it took the radio signal (travelling at the speed of
light!) to reach it. If you know time and speed, then you
can calculate distance. Once you have this from three
satellites, then the receiver can determine your position.
ACCURACY
You may have heard tales of extraordinary accuracy
from GPS receivers. The DOD requires accuracy of 10
to 15 meters from the satellite system. However, only
the military gets this precision. The way the military
keeps us and other unauthorized people from using the
more precise system is coding. In other words, the data
coming from the satellites is encrypted. Civilian GPS
receivers use “C/A Code.” Its accuracy is intentionally
worse than the military’s “P Code.” In this manner,
civilian users worldwide can benefit from excellent position fixes. Meanwhile, the military keeps the most
accurate system away from potential enemies. Theoretically, C/A code can give accurate position fixes up to
15 meters. This is more than adequate for most people.
However (as of this writing), the military isn’t satisfied
with C/A’s potential accuracy in the hands of the world.
So, it’s degrading it further with “Selective Availability” or
SA. This is small, random errors intentionally added to
the system so your accuracy will typically be within 100
meters. Of course, accuracy also depends on the angle
of the satellite above the horizon, signal-to-noise ratio,
the number of satellites tracked at one time (the more
3
the better), and other factors. The smallest ranges on
the plotter may not be usable if the SA is high. The
present position symbol can move off the screen even
while you’re sitting still.
Don’t let this discourage you. GPS by nature has much
faster updates than other systems (such as Loran), and
typically is much easier to use. Accuracy, even with SA
on is still better than most other navigation systems.
You’ve purchased one of the finest navigation instruments on the market today. We hope you’ll enjoy it for
many years to come.

The EAGLE™ GPS Receiver
The Rockwell GPS engine is currently used in all Eagle™
GPS receivers. It’s small, rugged, and fast. The five
channel design lets it track all satellites in view. It sends
position information to the AccuNav Sport™ from once
every second to once every five seconds (user selectable.) By incorporating Rockwell’s GPS receiver technology with Eagle’s state-of-the-art design and manufacturing capabilities, Eagle brings to the consumer one
of the most advanced GPS navigation systems available in the world.
ANTI-SKID
The AccuNav Sport™ has a recess molded into the
back of the case and one-half of a plastic fastener
attached to the recess. When used with the other half of
the fastener, it keeps the unit from sliding on a level
surface such as a dashboard.
NOTE: The adhesive anti-skid patch is not designed to
hold the AccuNav Sport™ on a vertical or overhead
surface. It is only to be used to keep the unit from sliding
on a flat, horizontal surface.
ANTI-SKID
To use the anti-skid material, first remove the fastener
from the literature pack supplied with the AccuNav
Sport™. Select the location for this fastener and peel the
plastic backing from this half and press it onto the
mounting surface. Align this patch with the one on the
AccuNav Sport™, then press them together. It will hold
the unit under mild vibration, keeping it from sliding.
5
EXTERNAL
POWER
EXTERNAL POWER
The AccuNav Sport™ uses six AA batteries or (using
the optional CA-1 adapter cable) 6 to 35 volts DC from
an external power source. To use external power (such
as a car's cigarette lighter), simply push the CA-1's plug
into the small connector on the side of the AccuNav
Sport™. Plug the other end of the CA-1 into the vehicle's
cigarette lighter, and the AccuNav Sport is ready for use.
(Note: A rubber plug comes with the AccuNav Sport to
cover the external power jack on the side of the unit
when it's not in use.)

BATTERY
INSTALLATION
BATTERY INSTALLATION
The AccuNav Sport™ requires six AA batteries.
We recommend DuraCell™ alkaline batteries, but
other brands will work. You can use lithium batteries which will last longer than alkaline batteries.
Rechargeable ni-cad batteries will also work in the
AccuNav Sport™, however they won't last as long
as alkalines. Do Not use heavy-duty batteries or
any battery other than the ones listed above. Do not
mix different types of batteries. (e.g. ni-cads and
alkalines)
To install the batteries, first turn the AccuNav
Sport™ so that it is facing you. Now grasp the
bottom part of the case and push it to the right until
it comes completely off the unit as shown at right.
The bottom part of the AccuNav Sport™ houses
the battery pack.
7
Now push the battery pack out the bottom of the battery
cover as shown at right. Install the batteries with the
negative end (-) toward the springs. The positive end (+)
should be firmly against the metal plate. When all six
batteries are installed in the battery pack, slide it into the
battery cover.
BATTERY
INSTALLATION
Notice!
There is a tab on the top of the battery holder that
aligns with a slot on the top of the battery cover. Make
certain the tab is aligned properly! Otherwise the
battery holder won't slide all the way into the cover
and the battery cover won't slide onto the unit.
If the battery holder sticks when sliding it into the battery
cover, apply a thin film of petroleum jelly to the "O" rings
on the battery holder.
Slide the battery pack onto the unit and the AccuNav
Sport is now ready for use.

BATTERY
SAVER
Vari-Power™ Battery Saver Feature
The AccuNav Sport™ has a five-level power saving
feature that can extend the life of the batteries considerably. It does this by changing the update rate of the
GPS receiver inside the unit. When you first turn the
AccuNav Sport on, the update rate is once per second.
In other words, the GPS receiver calculates and sends
your position to the display once per second. You can
lengthen this time to as little as once every five seconds.
The longer the update rate, the less power is drawn from
the batteries. For example, less power is drawn from the
batteries when the unit is in the five second update rate
than the one second rate. There can be exceptions to
this rule, however. Whenever the AccuNav Sport is
trying to lock onto the satellites, it automatically goes
into the one second update mode. If you are walking in
a wooded area with the unit set on the five second
update mode, the unit may lose its lock on the satellites
BATTERY
SAVER
due to the trees overhead. When this happens, the unit
automatically goes into the one second update mode
until it locks onto the satellites. Then it returns to the five
second mode. If you are walking through heavy tree
coverage with only occasional gaps in the trees, the unit
may remain in the one second update mode continuously. Typically, however, the AccuNav Sport™ will
consume less power with higher update rates under
normal conditions.
Although there is no indicator on the navigation or
plotter displays to show which update mode you are in,
watching the clock can show you the current mode. All
displays, including the clock are updated at the same
time. If you have it set for a three second update, then
the clock will "freeze" for three seconds, then show the
correct time, then "freeze" for three seconds and so on.
10
Also note that the AccuNav Sport™ automatically goes
into the one second update rate whenever external
power is applied to the unit. For example, if the CA-1
cigarette lighter adapter cable is plugged into the
AccuNav Sport and the other end is plugged into your
car's cigarette lighter, then the update rate will automatically switch to the
one second update.
To adjust the update
rate, turn the unit on
by pressing the ON
key. Next, press the
MENU key, then the
F5 key which corresponds to the
"CHANGE GPS
SETTINGS" label.
Now press the right arrow key to see the second menu
screen. The screen shown on the previous page appears. Press the F1 key which corresponds to the
"POWER SAVING SETUP" label. A screen similar to the
one below appears.
11
LOW BATTERY INDICATOR
When the battery voltage reaches six volts, a low
battery message appears in the lower left corner of the
display. If you are using alkaline batteries, and the unit
is in the one second update mode, then you will have
approximately 15 minutes or less until the unit automatically shuts off. If you have the unit in the five
second update mode, you will have approximately 45
minutes or less until the unit shuts off.
Note:
In cold weather, keep a spare set of batteries in a warm
place, such as a shirt pocket. Warm batteries last
considerably longer than cold ones.
LOW BATTERY
INDICATOR
The update rate currently in use shows
at the bottom of the
screen. This one is
currently using the
one second update.
To change it, simply
press the key corresponding to the desired update rate.
For example, to
change to a four sec-
ond rate, press the F4 key. The update rate changes to
once every four seconds and the display at the bottom
of the screen will show "CURRENTLY USING: 4 SEC."
To exit this screen, press the CLR key.
ANTENNA
The AccuNav Sport™ has a removable antenna that
folds over the display when the unit is not in use. To open
the antenna, simply lift on an edge of the antenna and
raise it to the desired angle.
Two thumbscrews on the antenna's hinge let you adjust
the tension on the antenna. This helps keep the antenna
in the desired position. The thumbscrews work in opposite directions. To tighten the right thumbscrew, rotate it
away from the display. To tighten the left thumbscrew,
rotate it toward the display.
Caution - Always make certain the left thumbwheel is
tight when using the AccuNav Sport™. The connector
for the antenna is inside the left thumbwheel. If it isn't
tight, a poor connection may occur. This can prevent the
AccuNav Sport™ from operating properly, if at all.
12
To remove the antenna, simply loosen the thumbwheels
until they won't turn. Carefully remove the antenna from
the unit by pulling it straight out. If you feel any resistance, make certain the thumbwheels are at the end of
their travel. Don't force any parts.
Once you remove the antenna, you can see it's connector inside the left-hand thumbwheel. When reinstalling
the antenna, align the left side of the antenna first, then
thread left thumbwheel until it engages the connector.
This will require two full turns of the thumbwheel. After
you've accomplished this, thread the right side of the
antenna by rotating the right thumbwheel. Remember to
rotate the right thumbwheel in the opposite direction
from the left.
Adjust thumbwheels until the desired tension is achieved.
Caution - Do not overtighten the thumbwheels.
13
ANTENNA ANGLE
When using the AccuNav Sport™, try to make certain
the antenna is parallel with the ground, or nearly so as
shown at right. Since the signals from the satellites are
"line of sight", a flat antenna gives you a better chance
of being able to receive the signals from all of the
available satellites.
Also, trees, buildings, carports (even your body), can
block the signals from the satellites. When using this
unit in heavy brush or timber, remember that it may lose
track on one or all of the satellites until you move into a
clearing.
We have successfully used the AccuNav Sport™ in
cars and trucks since the satellite's signal passes through
glass. However, antenna placement can make a difference in receiving the signals or not.
14
KEYBOARD
The keyboard has the main group of keys arranged in
three horizontal rows, plus four arrow keys at the top.
The keys are used to enter numbers, make menu
selections and activate the windows feature. The menu
key near the bottom left corner of the keyboard activates
the first menu page.
WIN - This key gives you access to the windows mode,
which has many combination displays.
POS - Press this key to show the Position Screen.
STR - Press this key to show the Steering Screen.
PLOT - This key gives access to the Plotter.
RTE - Pressing this key shows the route planning menu.
15
WPT - Pressing this key lets you save or recall a
waypoint.
ICON - To mark a location on the plotter screen, use this
feature.
CNTR - Pressing this key centers your position on the
plotter.
ZIN & ZOUT - These keys let you "zoom-in" or "zoomout" the plotter display.
OFF - Press and HOLD the Off key to turn the AccuNav
Sport™ off.
MENU - Press this key to show the menus and gain
access to most functions.
16
ENT - (Enter) Press this key to accept keyboard entry.
CLR - (Clear) This key clears menus and erases entries
from the screen.
ARROW KEYS - These keys are used to make menu
selections and to move objects on the screen.
ON - The ON key turns the AccuNav Sport™ on. It also
controls the lights. Pressing the ON key again after
turning the unit on turns the lights on. Press it a third time
and the lights are turned off.
NOTE:
The keys labeled F1 through F0 are used to select
menu items and enter numbers. For example, to enter
the number "495", you should press F4, then F9, and
finally F5.
OPERATION
TURNING POWER ON
To turn the AccuNav Sport™ on, simply press the "ON"
key. (Note: The "ON" key is harder to press than the
other keys. This makes it harder to turn the AccuNav
Sport™ on accidentally.) A screen similar to the one
shown below appears.
To turn the lights on,
press the F5 key. To
adjust the display
contrast, press the left
arrow key to lighten
the screen, the right
arrow key darkens it.
To clear the display,
press the CLR key.
17
MENUS
Most of the AccuNav Sport's™ features are found on
pages of "menus". Pressing the MENU key lets you view
the menus. This unit has four basic displays. They are:
Windows, Position, Steering, and Plotter. When you
press the MENU key, different menus appear depending on the display
mode the unit is in.
(Except the plotter
and steering displays
share the same
menus.) In other
words, if you press the
MENU key while the
position screen is
showing, the menu
shown at right appears. However, if you
18
press the menu key while the plotter is displayed, a
different menu appears as shown below. This gives you
the features specific to each display without having to
search through many pages of menus.
Unless otherwise specified, all menu examples used in
this manual are accessed while the position or steering
screen is showing.
More information on
menus are shown in
the back of this
manual.
Initialization - Power On
In order for the AccuNav Sport™ to lock onto the
satellites, it must first find them. If you simply turn the unit
on and wait, the unit will find the satellites by itself in 15
minutes or less. This is called “Cold Start.” If you let it find
the satellites, the time display will probably be wrong,
since it will be showing UTC time which is the time at
Greenwich, England. However, all other navigation
displays, including the position display will be correct.
(You can set the time display to your local time.) To
speed up the satellite acquisition process, you can
initialize the AccuNav Sport™ or “tell it where it is” the
first time it’s turned on. This initialization process is
usually done only once and requires the following data:
The unit usually only takes a few minutes or less to find
the satellites once it’s been initialized by the user.
After the batteries are installed and the antenna is
opened, press the ON key, then press the MENU key.
Now press the key next to the “CHANGE GPS SETTINGS” label. Finally,
press the key next to
the “SET LAT, LON,
ALT, TIME, DATE”
label. The screen
shown at right appears.
1. Approximate present position in latitude/longitude
2. Approximate elevation above sea level (altitude)
3. Today’s date and time
19
This is the GPS setup screen. The settings now in use
are shown at the top of the display. If you’re using the
unit for the first time, these settings are probably wrong
for your position and time. To change any of the numbers on this display, first press an up or down arrow key
to move the black box to the desired label. For example,
to change the local
time, press the down
arrow key until the
black box is on the
“LOCAL
TIME”,
press the F6 key,
then enter your time
using the numbered
keys.
20
CHANGE POSITION
To change the position shown on the AccuNav Sport's
display, first determine your approximate position. Use
a chart or call your local airport to determine your
position if you don’t know it. The latitude/longitude that
you enter doesn’t have to be extremely accurate. Typically, if you enter a position within a few degrees of your
present position, the AccuNav Sport™ should quickly
find your actual latitude/longitude. To change your
present position, first move the black box to the LATITUDE display, then press the F6 key to change it. The
screen shown at right appears. Use the down arrow key
to change the “N” to “S”, if necessary. Next, simply enter
your present latitude using the numbered keys. Notice
that the position entered is in degrees, minutes, and
hundredths of a minute. (Not seconds!) If you make a
mistake, press the left or right arrow keys to move to the
number in the latitude that needs changing. After the
latitude has been entered, press the ENT key.
Now move the black box to the LONGITUDE display.
Enter your present longitude within a degree. Use the up
or down arrow keys to switch to east or west longitude,
if necessary. Now enter the longitude using the numbered keys. Be certain to enter a zero
“0” as the first number in the longitude if
it’s less than 100 degrees! After you’ve
entered the last number, press the ENT
key.
21
CHANGE ALTITUDE
To enter your present altitude, move the black box to the
ALTITUDE display, then press the F6 key. The AccuNav
Sport™ needs to know your elevation above sea level.
(Not your height above the ground.) Again, an approximation within a few thousand feet is usually sufficient.
Use the numbered keys to enter your altitude data.
Press the up arrow key if your altitude is below sea level.
For example, suppose you’re in Death Valley and the
spot you’re standing in is 35 feet below sea level. You
would need to enter the numbers “35”, then press the up
arrow key to change it to -35 feet. Press the ENT key
when you’re done.
CHANGE TIME
To change the local time (the time at your position),
move the black box to the LOCAL TIME display, then
press the F6 key. The screen shown at right appears.
Use the number keys to enter the time. Press the up
arrow key to change the time from AM to PM or the down
arrow key to change from PM to AM. Press the ENT key
when you’re finished.
CHANGE DATE
To enter today’s date,
move the black box
to the LOCAL DATE
display, then press
the F6 key. The
screen shown on the
next page appears.
Enter the date using
the numbered keys.
When you’re finished,
press the ENT key.
22
The numbers at the top of the screen should be correct.
If they aren’t, press the key next to the label that you
need to change. If everything is correct, press the key
next to the “EXIT” label. The unit will switch to the
position screen and start searching for the satellites
currently in view. The AccuNav Sport™ should find the
satellites and show a
position in a few minutes.
COLD START
When the AccuNav Sport™ is turned on for the first time
“out of the box”, it automatically sends a “cold start”
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’ve 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. For example, giving it east longitude instead of west. Or if
you’ve moved a long distance with the unit turned off.
The unit will automatically issue a cold start to it's
internal GPS receiver, however, you can send a cold
start at any time.
To send a cold start message to the receiver, press the
MENU key. Now press the key next to the “CHANGE
GPS SETTINGS” label. Finally, press the key next to the
“GPS “COLD” START” label. The unit will begin a cold
start technique to find the available satellites. It should
lock on to them in 15 minutes or less. Remember, when
it does, your local time and possibly date display will
probably be wrong. Use the method shown previously to
set the time and date
to their proper local
settings. 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.
23
POSITION/NAVIGATION DISPLAYS
The AccuNav Sport™ has a position screen, plotter,
steering indicator, and a satellite information screen.
These displays were designed to show the most important data. However, using the Windows feature, many
more screens are available that show navigation information in various arrangements. See the Windows
section for more detail.
DO NOT NAVIGATE WITH THIS UNIT UNTIL YOU
HAVE FOUND THE REASON THE UNIT HAS LOST
THE SATELLITES!
Each of the following screens (except the satellite
information screen) is available by pressing its key.
(Press the MENU key,

your present position!
POSITION SCREEN
24
SATELLITE INFORMATION SCREEN
The satellite information screen shows technical data
about each satellite in view. The AccuNav Sport™ has
a five parallel channel GPS receiver. Data on each
channel is shown at the top of the display. The channels
are numbered one through five on the left side of the
screen. Every satellite in the constellation has a number
assigned to it, called the PRN. The PRN is the first
number in the channel’s row. TRK stands for “track.” If
it's tracking the satellite, then a “T” is placed in this
column. If the AccuNav Sport™ is searching for the
satellite, then a “S” appears. ELV is the elevation
(height) of the satellite above the horizon from your
position. AZM is the azimuth or direction of the satellite
from your position. For example, if the azimuth of a
satellite is 180 degrees, then it is due south of your
position. SNR is the signal-to-noise ratio. This tells you
how strong the satellite’s signal is. The higher the SNR
number, the better. Typical good SNR numbers are
between 30 and 50.
The satellites that are visible in the sky from your
position are shown in the lower right corner of the screen
under the “VISIBLE SATS”.
In the lower left corner of the screen are
the DOPS displays.
These show you the
“Dilution Of Precision”
(DOP) for the horizontal (HDOP), geometric (GDOP), position
(PDOP),
time
(TDOP), and vertical
(VDOP). The GDOP
is the combination
25
value of HDOP, VDOP, and TDOP. The smaller the
GDOP’s number is, the better. The GPS receiver selects satellites based on GDOP, therefore it always tries
to use satellites that have good DOP values. These

and any ground based obstructions.
Remember, the smaller the number - the better on all of

POSITION SCREEN
The position screen automatically appears after the
AccuNav Sport™ is initialized or you can view this
screen at any time by pressing the POS key. The
position display shows your present position (POSITION), bearing (BRG), course over ground (COG), local
time, cross track error (XTE), time to go to waypoint
(TTG), and waypoint name (WPT NAME).
26
Your present position shows near the top of the screen
in latitude/longitude coordinates. This is shown in degrees, minutes, and thousandths of a minute. For example, on this page, the present position is 36 degrees,
8.987 minutes north latitude and 95 degrees, 50.553
minutes west longitude. Below the present position on
the left side is the
Bearing to Waypoint
(BRG) display. This is
expressed in degrees
true or magnetic, depending on the mode
the AccuNav Sport™
is in. To the right of
the Bearing is the
Course Over Ground
(COG) display. At the
bottom of the screen
are the Local Time and Cross Track Error Displays.
Please note that you must recall a waypoint to use the
Bearing and Cross Track Error displays.
STEERING SCREEN
The steering screen shows a pictorial view of your
vehicle and course travelled. This is called a Course
Deviation Indicator or CDI. It also shows Distance To
Go (DTG), Speed Over Ground (SOG), Bearing to
Waypoint (BRG), and Course Over Ground (COG).
Press the STEER key to view this screen.
Your present position is shown by the arrow. The arrow
shows the direction your vehicle is heading relative to
the waypoint. In theory, if you steer with the arrow
always pointing towards the waypoint, then you will
arrive at the waypoint. The solid line extending from the
arrow is your track or path you’ve taken. To travel
directly to a waypoint, try to keep the arrow on the center
line. The waypoint is depicted by a box at the top of the
CDI display. As you approach the waypoint, the arrow
and the box will move closer together. If you travel past
the waypoint, the waypoint’s box will move to the bottom
of the display.
The numbers on the
top left side of the
screen are distance
markers, showing the
remaining distance to
the recalled waypoint.
If the numbers have a

PLOTTER
The plotter lets you see your course and direction of
travel on the screen. If you’ve recalled a waypoint, the
plotter shows your starting location, present position,
and destination. However, you do not have to recall a
waypoint to use the
plotter.
The plotter also can
show grid lines on the
display. These grid
lines show latitude
and longitude lines
that can help you see
your position or the
location of other objects.
To use the plotter, simply press the PLOT key. A screen
similar to the one at the bottom of the previous page
appears.
The flashing cross is your present position. The solid
line is your current track, or path you have just traveled.
The large square is a compass rose marked with North,
South, East, and West. The square’s height and width
shows at the bottom of the screen. This is the distance
from one side to the other and from the top to the bottom.
Your present position is shown at the top of the screen.
If your present position starts to move outside the
square, the AccuNav Sport™ clears the display, then
redraws your present position closer to the center of the
screen. Your present position will always be displayed
on the plotter. To clear the plotter screen, see the Plotter
Menus section.
On the left side of the screen are the Distance To Go
(DTG), Speed Over Ground (SOG), Bearing (BRG), and
Course Over Ground (COG) digital displays. All of these
displays are only used when a waypoint is recalled,
except COG and ALT which are always active. These
displays also can be customized. See the Plotter Menus
section for more detail.
PLOTTER CURSOR
The plotter cursor can help you determine the latitude/
longitude of a waypoint or event marker. To use it, press
the up or down arrow key while the plotter is displayed.
A screen similar to the one on the next page appears.
Two new lines appear on the screen. These are the
plotter cursor lines. Also, the present position display at
the top of the screen switches to show the latitude/
longitude position of the plotter cursor - not your present
position. The distance and bearing from your present
31
position to the cursor position show in the bottom left
corner of the display. Use the arrow keys to move the
cursor lines anywhere on the plotter. To erase the
cursor lines, press the CLEAR key. This will switch the
display at the top of the screen back to your present
position and erase the distance and bearing displays at
the bottom of the
screen.
PLOTTING WITH A WAYPOINT
Using the plotter with a recalled waypoint or route is an
easy way to see the distance and direction you travelled. It also simplifies navigation. To use the plotter in
this manner, first recall a waypoint or start a route. (See
the Waypoint Recall section for more information.) Then
press the PLOT key.
A screen similar to
the one at right appears.
The circle with the “S”
is your starting location. This was your
position when you
recalled the waypoint. The flashing
circle with a cross is
32
your present position. The “flag” with a number inside is
the destination (recalled waypoint). The number inside
the flag is the recalled waypoint number. In this example, waypoint number 1 is the destination. The dotted
line is the shortest, most direct course from the starting
point to the destination. Follow this line to get to the
waypoint.
An arrival alarm can be set to sound a tone when you
come within a preset distance to the destination. See the
section on alarms for more information about the arrival
alarm.
PLOTTER MENUS
Pressing the MENU key while the plotter is showing
gives you a new set of menus that relate only to the
plotter. There are two plotter menus. The first menu is
shown at right.
PLOTTER MENU - PAGE 1
SET RANGE
Press the F1 key to see the plotter's range menu. (See
the screen at the top of the next page.) This menu
changes the plotter’s range or distance across the
plotter’s display. The
range is one (1) mile
when the AccuNav
Sport™ is turned on
for the first time. The
available plotter
ranges are .1, .2, .5,
1, 2, 5, 10, 20, 50,
100, 500, and 1000
miles. This lets you
“zoom in” to see small
variations in your
33
course or “zoom out”
to see your starting
position, present position, track, course,
and destination.
NOTE: An easier
way to change the
plotter's range is to
simply press the ZIN
key to "zoom-in" or
the ZOUT key to
"zoom-out".
SAVE PLOT TRAIL
The AccuNav Sport™ can save up to five (5) plotter
trails. Saving plot trails makes it easier to follow an old
path to a destination. Simply save your current trail, then
recall it later to use as a guide. Every time you turn the
AccuNav Sport™ off, it saves your current trail on the
screen. To save it under a number that you
can recall later, first
press the MENU key
while the plotter is displayed. Now press the
F3 key. The menu

trail that you wish to recall. For example, to recall plot
trail number three, press the F3 key. The AccuNav
Sport™ returns to the plotter screen and draws the
recalled trail on the screen. Note that this recalled trail
doesn't affect your current trail; both will be displayed.
Also note that the recalled plot trails are position specific. In other words, the plot trail is not simply a line
drawn on the screen, it represents the location you were
in when the plot trail was drawn.
ICON ON/OFF
Pressing the F5 key while the first plotter menu is
displayed turns the icons off that you placed on the
screen using the ICON key. For more information on this
feature, see the ICON section. This also turns off all of
the waypoint icons.

ICONS
The AccuNav Sport™ can place icons on the plotter to
mark special locations. There are five different icons to
choose from and there are 100 of each icon for a total of
500. You can place each icon individually, however, you
have to erase all of the icons in a group.
40
To place an icon, first press the ICON key. The screen
shown below appears.
Now select one of the five icons shown on the left side
of the screen by pressing the key corresponding to the
desired icon. For example, to place the fish symbol,
press the F1 key. As
soon as you press the
key, the AccuNav
Sport™ places the
icon at your present
position as shown on
the far right side of
the next page. This
icon always stays in
this location. It’s
saved in memory so
it will always show on
the display, even if the unit is turned off and on again.
Note that there are two different sets of symbols available - land and marine. When the AccuNav Sport™ is
turned on for the first time or after it's preset, the marine
set of icons (shown on the previous page) is in use. To
switch to the land
icons, press the F6
key. The screen
shown at right appears, giving you five
other icon choices.
Note: You can't mix
land and marine
icons.

ROUTES
A route gives you the ability to navigate to several
waypoints without having to reprogram the unit after
arriving at each one. A route consists of two or more
waypoints. When you start on a route, the AccuNav
Sport™ shows navigation information to the first waypoint in the route. When you reach the first waypoint,
(signalled by the Arrival Alarm), the AccuNav Sport™
automatically sequences to the next waypoint. Navigation information is shown to this waypoint and the
process repeats. When you reach the last waypoint in a
route, the arrival alarm sounds until you turn it off. At this
point you should use the "Cancel Navigation" feature to
stop the AccuNav Sport™ from showing navigation data
to the last waypoint in the route. Otherwise, it will
continue to navigate to that waypoint, even if it's turned
off and on again.
There are four steps required to create and follow a
route. First, you must create and name the route. Next,
select the waypoints used in the route. Then determine
the starting waypoint. Next, tell the unit to follow the
route. Finally, the unit will ask you if you wish to run the
route forward or backward. After these steps are completed, the AccuNav Sport™ will start showing navigation data to the first waypoint on the route.
NOTE: The plotter shows all of the waypoints on a
recalled route connected by a dotted line.

CHANGING GPS SETTINGS
For the fastest position acquisition, the AccuNav Sport™
must be initialized when it’s turned on for the first time.
This is described at the beginning of the GPS section in
this manual. However, if you wish to change only one of
the parameters (such as time), press the MENU key,
then press the F5
“CHANGE GPS SETTINGS” key. Finally,
press the F1 “LAT,
LON, ALT, TIME,
DATE” key. The
screen shown at right
appears.
Using the menus on
this and following
menu pages, you can
change the initial po60
sition, time, date, or altitude without affecting any other
initialization setting. All of these menus work identically
to the ones described in the initialization section at the
beginning of the GPS section. After you make a change,
the unit returns to the GPS or plotter screen.
You may need to re-initialize the unit if you move a long
distance (over 100 miles) with the unit off. In this case
you would need to enter a new initial position to help the
AccuNav Sport™ find the correct satellites quicker.
GPS MODULE SELF-TEST
This feature tests the GPS module and returns a special
code. This code is of interest only to the service department. However, the AccuNav Sport™ interprets this
code and displays a status message. This message is
either “MODULE HAS PASSED” or “MODULE HAS
FAILED” and shows at the bottom of the screen. The
current software version number also appears near the
bottom of the screen. Contact the factory customer
service department if the module fails the self test. DO

GPS SIMULATOR
This feature places position and navigation data on all
screens, including the plotter. The unit “navigates” a
closed course. It shows bearing and distance to go,
course over ground, and other information. A recurring
message appears, alerting you that the simulator mode
is enabled. DON’T NAVIGATE WHEN THE SIMULATOR IS ON!
To turn the simulator on, press the MENU key twice,
then press the F5 (GPS SIMULATOR OFF ON) key. The
simulator mode starts immediately. To turn the simulator off, either press and hold the OFF key or repeat the
above steps.
NMEA/DGPS WIRING
The AccuNav Sport™ can send NMEA 0183, version
1.5 data to another device. It can also receive position
correction data from a DGPS (Differential GPS) beacon
receiver for high position accuracy. A connector on the
back of the unit (see photo at right) is used for these
connections. A rubber plug covers this connector when
it's not in use.
The following NMEA 0183 sentences are sent from the
AccuNav Sport™:

wires- red, black, brown, blue, green, white and a
braided shield. The red (positive) and shield (ground)
wires are power input (+6 to +35 VDC) to the AccuNav
Sport™. If the red wire is not used, tape its end so that
it cannot short. The white and green wires are for a
NMEA interface and/or a DGPS beacon receiver. The

SELECT NMEA
The AccuNav Sport sends data out the white wire on the
optional NMEA cable according to standards set by the
NMEA (National Marine Electronics Association). This
allows the AccuNav Sport to send position and navigation information to “listener” units, such as charting
instruments, autopilots, and other marine instruments. The
AccuNav Sport uses
the following NMEA
data
protocols:
NMEA 0180 and
0183. NMEA 0180
sends steering information only. It’s useful mainly for marine
autopilots. NMEA
64
0183 sends position, steering, speed, and more. In
order to use this feature, the white wire on the optional
NMEA cable must be connected to the NMEA data input
on the other instrument. See the installation section in
the front of this manual for wiring connection information.
The AccuNav Sport also has the capability to receive
differential data from a beacon receiver. This gives the
unit much better accuracy than normal. However, before purchasing and installing a beacon receiver, make
certain there are transmitters in the area you wish to
use. Presently, the AccuNav Sport can use the Magnavox MX-50R or StarLink MRB-2A. Please note that
the AccuNav Sport doesn't send NMEA 0183 data when
the Magnavox MX-50R beacon receiver is activated.
NMEA SETUP
Once you connect the wiring properly, the AccuNav
Sport must be told which NMEA data format to use.
Consult the owner’s manual of the other equipment to
see which format it needs. Then set the AccuNav Sport
as follows:
First, press the MENU key. Next, press the F5 (CHANGE
GPS SETTINGS) key. Now press the F2 (SELECT
NMEA/DGPS) key. The screen shown on the previous

TRUE and MAGNETIC POSITION
True and magnetic north are not the same. True north is
the top of the world. It’s where all lines of longitude
converge. Magnetic north is the location our compasses
point. It lies several hundred miles to the south of true
north, at a location in Canada.
Charts are usually laid out according to a Mercator
projection that uses true north. If you plot a course on a
chart using the Mercator projection, you’ll either have to
convert magnetic readings to true or use true readings.
The AccuNav Sport can display navigation information
in magnetic or true. When it’s turned on for the first time
magnetic is used. To switch to true, first press the MENU

Both the display and keyboard are backlighted for use
at night. To prevent excessive current drain on the
batteries, when the battery voltage is less than 9.0 volts,
the lights will stay on for 30 seconds, then automatically
turn off. Press any key to turn them on again. To turn the
back lighting on, simply press the ON key. To turn the
backlights off, press the ON key again. There is a back
light on/off switch on the position screen's third menu

PRESET
The Preset feature returns all GPS units to their original
factory settings. This resets the units of measure, speaker
volume, display contrast, and more. This doesn’t erase
any waypoints or routes, however it does erase plotter
trails.
To preset the unit, press the MENU key until the “PRESET UNIT” label appears. Press the key corresponding
to that label. The menu screen disappears and the
AccuNav Sport™ returns to the GPS position screen. All
units will be returned to their factory settings.
PCF OFFSET
The GPS navigation system relies on complex mathematical calculations to determine your position based
on satellite data and other factors. One factor is the
Earth's shape. Since the Earth is not a true sphere,
variations in the calculations have to be made to accommodate deviations. To make matters more complex, not
everyone uses the same data to determine what the
deviations are. The size and shape of the ellipsoids that
are used to approximate the earth's surface are improved often. This can lead to errors if your navigation
device uses one ellipsoid, while your chart uses a
different one. The term used for these ellipsoids is
"Datum."
add this offset to all position displays at all times.
Remember, the GPS error is very dynamic and the PCF
offset should never be used in an attempt to cancel the
error. In general terms this feature should only be used
if your map indicates what the possible error is. This
feature should always be reset to zero (0) when
you're finished with that chart.
For example, suppose you are stopped at a location that
is accurately marked on a chart. Your unit shows a
longitude position that is .010 degrees less than the one
on the chart. Using the Position Correction Factor (PCF)
Offset feature, you make the unit read the same as the
