3.7 Using Tracks
The Track function is used to mark on-screen the trail that your vessel has
followed, as if it had left a visible fixed wake.
While the track is switched on it is recorded in the display unitsmemory.You
specify the interval at which track points are made and a line is drawn on-
screenbetween eachpoint. Up to 4500 trackpoints canbe saved in total: inthe
current track and in up to 5 track files (each a maximum of 750 points). The
current track remains on-screen, even following a power off/on, until you
clear the track.
Breaks in the track will be caused when any of the following occur for longer
than the specified track interval: the track is switched off then on; the position
fix is lost; the display unit is switched off.
To enable you to follow this track on your return voyage, the SmartRoute
function converts the track (or the last segment of a track with breaks) into a
route which is automatically reversed, see SmartRoute on page 3-41.
A track can be saved and retrieved for display at a later date. 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.
