TracBack Tips
When a TracBack has been started, the GPSMAP 196 divides
the track into segments called legs. Up to 50 temporary turns are
created to mark the most significant features of the track in order to
duplicate your exact path as closely as possible. To get the most out
of the TracBack feature, remember these tips:
• Always clear the track log at the point that you want to go
back to (such as a dock or campsite).
• The Record Mode option on the Active sub tab must be set to
Fill or Wrap .
• If the track log Interval option on the Active sub tab is set to
the Time option, the route may not navigate your exact path
(keep the interval set to Resolution for best performance).
• If the receiver is turned off or satellite coverage is lost during
your trip, the TracBack draws a straight line between any
point where coverage was lost and where it resumed.
• If the changes in distance and direction of your track are too
complex, the waypoints may not mark your path accurately.
The receiver then uses the most significant points of your
track so there are fewer changes in direction.
