Once a TracBack has been activated, the GPSMAP 2006/2010 takes the track log currently stored in
memory and divides it into segments called ‘legs’. Up to 254 temporary ‘turns’ are created to mark the
most significant 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, 254 points may not mark
your path accurately. The receiver then assigns the 254 points to the most significant points of
your track, and simplifies segments with fewer changes in direction.
