3.7Using 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 plotter 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 3-44.

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.
