Changing the track
control
The 957 displays your track history as a series of dots
indicating the path you’ve recently traveled. You can choose
how often to store a position fix as a point in your track
history. The 957 stores up to 1,024 position fixes. When it
reaches this limit, the 957 starts erasing the oldest points to
add your new points to the track line. The more often you
mark your track, the faster you fill up the track memory. The
maximum track length depends on how often points are
stored.
