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.
