• 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.)
• If the receiver is turned off or you lose satellite
coverage during your trip, the TracBack route will
simply draw a straight line between any point
where coverage was lost and where it resumed.
• If the changes in direction and distance of your
track log are complex, 30 waypoints may not be
enough to accurately mark your exact path. The
receiver will then assign the 30 waypoints to the
most significant points of your track, and simplify
segments with fewer changes in direction.
• To save a TracBack route, copy route 0 to an open
storage route before activating another TracBack.
Activating another TracBack or storage route will
overwrite the existing TracBack route.
• Whenever a TracBack route is activated, the
receiver will automatically erase any temporary
waypoints that are not contained in routes 1-19.
If there are temporary waypoints stored in routes
1-19, the receiver will create any new temporary
waypoints using the first three-digit number
available. (You can also quickly delete all tempo-
rary TracBack waypoints in memory by using the
‘delete by symbol’ method described on pg. 21.)

The TracBack feature will
navigate your track log
back to the oldest point in
the receiver’s memory.
REFERENCE
TracBack
The track log will be
divided into segments with
temporary waypoints to
create a route back to the
beginning of the track log.
