Station Keeping
There may be a time when you want to maintain your position at a
given location in open water. Some applications for this need may
be:
¾ Staying over a dive wreck.
¾
Staying over a fishing hole.
¾ Recovering an oceanographic survey point.
You can easily accomplish this task by two methods: by placing the
marker in
PLOT2 on the location you want to maintain and by refer-
ring to the bearing and range in PLOT2 to maintain the position. If
you are placing and recovering crab pots along a course line, you can
enter your course in the
RTE1 screen, then place the marker at each
crab pot in turn.
You can also select WPT Pass Criterion: Distance to WPT in the
CFG1 Navigation screen and set the WPT Pass Distance: 0.00; or
set the WPT Pass Criterion to Manual .
By doing this and putting the coordinate you want to maintain in the
RTE1 screen, you will always get the bearing and distance to the
waypoint in the PLOT1 and NAV screens, regardless of your angle
