Tracks - Garmin eTrex Mariner Owner's Manual And Reference Manual

Using Track Logs - Overview
The eTrex Mariner draws an electronic breadcrumb trail
on the Map Page as you travel along. This breadcrumb
trail is called a 'Track Log'. The Track Log contains infor-
mation about points along its path, including time and
position. The eTrex Mariner uses this information to allow
you to navigate using the saved track.
The 'TracBack' feature allows you to return along a
traveled path without marking any waypoints. When you
are ready to return to where you started, the eTrex Mari-
ner will take you back by following the 'Track Log' that
you left behind. You can save a total of ten tracks in the
unit memory. The Track Log starts recording as soon as
the unit gets a satellite location fi x and the Track Log
feature is turned on.
If you want to keep a record of a certain track
log or use the 'TracBack' feature, it is recommended that
you clear the Track Log before you start traveling. The
percentage of memory used by the current track log is
displayed in a window at the top of the page. After the
Track Log is 'Cleared', it will show zero percent. When
the display shows 99%, the most recent track points will
start overwriting the least recent. To avoid losing track
points you want, save the Track Log before it reaches the
99% mark.
The Saved Track Page displays the track and it can also
be displayed on the Main Map Page as you navigate.
The 'TracBack' feature allows you to retrace your track
in both directions. Tracks are marked BEGIN and END.
You can set the track recording interval to Distance,
Time, or Automatic. You can set the Track display resolu-
tion to High, Medium, Low, and Lowest. You can also use
the options menu to delete all saved tracks.
