TracBack Navigation (Navigating a Track)
TracBack allows you to retrace your path using the track log
automatically stored in the receiver’s memory. This eliminates the
need to store waypoints along the way. TracBack routes are created
by reducing your track log to a route of up to 50 turns and activating
an inverted route along those points. Once activated, a TracBack route
leads you back to the oldest stored track log point, so it is a good idea
to clear the existing track log before you of your current trip. Refer to
the “Track Tab” on page 55 for more information.
