Chapter 4 - Using the Chart Screen
Changing the track
control
The 958 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 958 stores up to 1,024 position fixes. When it
reaches this limit, the 958 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.
To display the
TRACK CONTROL
screen, press the

and the corresponding track length:
•
every 1 second for 60 minutes total
