3.9 Using Tracks
The Track function is used to mark, on-screen, the trail that your vessel
has followed, as though it had left a visible fixed wake.
While Track is on, it is recorded in memory as the Current Track and is
retained following a POWER OFF/ON. You specify the interval at which
track points are created and a line is drawn on-screen between each point.
The current track remains on-screen until you clear the track.
Breaks in the track will be caused when any of the following occur for
longer than the specified interval: the track is switched off then on; the
GPS fix is lost; the chartplotter is switched off.
Using the SmartRoute function, a track (or the last segment of a track
with breaks) can be converted to and saved as a route which is
automatically reversed, ready for use as your return voyage, see
SmartRoute on page 3-50.
A total of 4500 track points can be saved, in up to five track files (each
containing a maximum of 750 points).
The Current Track can be saved, named and retrieved for display at a later
date. For example, you may wish to display a previous track and place
waypoints along it that you can follow. You can only display one track at
a time; you must clear a current track from the screen if you want to
display a saved track.
This section describes how to:
• Set up a track and specify the Track Point interval.
• Clear the Current Track.
