Once a TracBack has been activated, the GPSMAP 2006/2010 will take the track log currently stored in
memory and divide it into segments called ‘legs’. Up to 50 temporary ‘turns’ will be created to mark the
most signifi cant features of the track log in order to duplicate your exact path as closely as possible. To get
the most out of the TracBack feature, remember the following tips:
• Always clear the track log at the beginning of your trip.
• The ‘Record Mode’ option on the track log setup page must be set to ‘Fill’ or ‘Wrap’.
• There must be at least two track log points stored in memory to create a TracBack route.
• If the track log interval is set to the ‘Time’ option, the route may not follow 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 will draw a
straight line between any point where coverage was lost and where it resumed.
• If your track log’s changes in distance and direction are too complex, 50 points may not mark
your path accurately. The receiver then assigns the 50 points to the most signifi cant points of
your track, and simplifi es segments with fewer changes in direction.
