To get the most out of the TracBack feature, remember these
navigating tips:
• Always clear the track log at the point that you want to return
to, such as the camp site or dock.
• Set the Record Mode option on the track log setup page 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 is set to Time, 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, TracBack draws a straight line between any point
where coverage was lost and where it resumed.
• If your track's changes in distance and direction are too
complex, 50 waypoints may not mark your path accurately. The
receiver then assigns the 50 waypoints to the most significant
points of your track and simplifies segments with fewer
changes in direction.
To stop TracBack navigation, press NAV. Highlight Stop Navigation
and press ENTER. For more information on setting up the Track
options and saving tracks, see pages 55-56.

MOB

Man OverBoard (MOB) allows you to simultaneously mark your
current position and set a course to a location for quick response to
emergency situations.
Highlight Yes and press ENTER to start navigation.
To activate the MOB function:
1. Press and hold MOB, or press MOB twice.
2. Press ENTER to confirm and begin navigating to the MOB.
Once a MOB has been activated, 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 waypoints are stored in
the waypoint list and may be deleted like any other waypoint. To
stop navigation to the MOB location, press NAV, highlight Stop
Navigation, and press ENTER.
