Position Pinning
When you are standing still or moving at extremely slow speed, a GPS
receiver can have trouble determining the direction you are traveling.
In the past, this resulted in a "wandering" plot trail that moved around
the map, even if you were standing still.
The Position Pinning feature was developed so that when you stopped,
the unit locked the present position on the GPS plotter until you moved
a short distance or exceeded a very slow speed.
The command remains available in the unit's software, but we recom-
mend that you leave it in the default off (unchecked) mode. The "wan-
dering" plot trail issue has now been corrected by the Track Smoothing
feature. Turning on Position Pinning could actually result in an inaccu-
rate plot trail if you are moving around in a relatively small area. If you
want to experiment with Position Pinning, the same instructions are
used to turn the feature on (checked) and off (unchecked.)
