TracBack Tips
When a TracBack is active, the GPSMAP 3205 takes the track log stored in
memory and divides it into segments called legs. Up to 300 temporary turns
(BEGIN, TURN 1, TURN 2,...., TURN X, END) are created to mark the most
significant features of the track log 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 starting point.
• The Record Mode option on the track log setup page must be set to
Fill or
Wrap .
• At least two track log points must be stored in memory to create a
TracBack route.
• If the track log Interval field is set to
Time
, 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,
TracBack draws 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,
300 waypoints might not mark your path accurately. The receiver then
assigns the 300 waypoints to the most significant points of your track, and
simplifies segments with fewer changes in direction.
Man OverBoard (MOB)
Use the Man OverBoard function to simultaneously mark and set a course to a
location for quick response to emergency situations.
To initiate the MOB function:
1. Press and hold the NAV/MOB key.
2. Press the Yes soft key to confirm and begin navigating to the MOB
location.
When a MOB is initiated, a MOB waypoint with an international MOB symbol
is created, and the unit is on an active navigation to that point. Use any of the
navigation pages to guide you back to the MOB point. The MOB waypoint is
stored in the waypoint list, and you can delete or edit it like any other waypoint.
