positions are stored in the track log. The default setting
is ‘auto’, which records track points based upon a set

setting gives the most efficient use of track memory
and provides the best TracBack performance.

a specific time interval:
1. Highlight the ‘METHOD’ field, and press
E
.

Setup
Entering a large time
i n t e rval into the track
re c o rding criteria may
plot your position points
f u rther apart than they
would be in the ‘AUTO’
setting. This will increase
the distance you can trav-
el without using up your
track log, but will greatly
reduce the effectiveness of
TracBack.
