TRACKER 5100/5100i/5500/5500i Installation and Operation Manual
NAVMAN
If Projected course is turned on, then the TRACKER
will display the projected position based on the
course over ground (COG), speed and a specified
time. To turn Projected course on and off and to set
the time, see section 13-2.

Tracking records the boat’s position to memory at
regular intervals, which can be:
Time intervals.
Or distance intervals.
The track of where the boat has been can be
displayed on the chart. The TRACKER can display
one track while recording another.
To work with tracks, (see section 13-5).
The TRACKER can store five tracks:
Track 1 can hold up to 2000 points and is intended
to record the normal progress of the boat.
Tracks 2, 3, 4 and 5 can hold up to 500 points
each and are intended to record sections to be
retraced accurately, for example entering a
river mouth.
Tip: Record the tracks in good conditions.
When recording is on and the track becomes full
then recording continues and the oldest points in the
track are deleted. The maximum length of a track
depends on the selected track interval: a small
interval will give a shorter, more detailed track and a
long interval will give a longer, less detailed track, as
shown in these examples:
