Track Setup Page
The track setup page lets you manage the GPS 12’s
track log data (see pg 24). You can also select whether to
record a track log and define how it is recorded.
To turn the track log on or off:
1. Highlight the ‘RECORD’ field, and press
E
.
2. Select ‘OFF’, ‘FILL’, or ‘WRAP’, and press

Track Method
The track ‘method’ option determines how often
positions are stored in the track log. The default setting
is ‘auto’, which records track points based upon a set
variance from your projected course over ground.. This
setting gives the most efficient use of track memory
and provides the best TracBack performance.
To change the method to record points based on
a specific time interval:
1. Highlight the ‘METHOD’ field, and press
E
.
2. Select ‘TIME INTERVAL’, and press
E
twice.

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.
