Tips on Creating and Using the TracBack Feature
To get the most out of the TracBack feature, remember the following tips:
• Always clear your track log at the exact point that you want to go back to (trail head,
truck, dock, etc.).
• The ‘record’ option on the track log setup page can be set to either the ‘wrap’ or ‘fill’
positions (see p. 42).
• There must be at least two track log points stored in memory to create a TracBack
route.
• If there are not enough available waypoints in memory to create a TracBack route, you
will be alerted with a ‘waypoint memory full’ message, and the receiver will use any
available waypoints to create a TracBack route with an emphasis on the track log closest
to the destination (the oldest track log point in memory).
• If the ‘method’ option on the track log setup page is set to a time interval, the TracBack
route may not follow your exact path. (Keeping the criteria set to automatic will always
provide the most detailed TracBack route.)
