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’ve
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. Now
highlight the “Pinning” label. Finally, press the left arrow key.
ALARMS
The Eagle Explorer has several alarms. You can set an arrival alarm to
flash a warning message when you cross a preset distance from a way-
point. 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 way-
point. 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 key to move the black
box to the desired alarm, then press the right ar-
row key to turn it on.
To adjust an alarm’s distance, move the black box
to the alarm’s “DIST” menu item, then press the
right or left arrow keys to increase or decrease
the alarm’s distance.
