Introducing tracks

What is a track?
Why use a track?
Page 9-2
The term track refers to a path that you either plan to follow or
have already followed. The track is a sequence of position
measurements that is automatically recorded every five
seconds—as you travel from point A to point B and beyond.
The master track is a continuous record of everywhere your
vessel has travelled during the last 14 days. You can select a
portion of this master track, then name and store it in the
database to overlay on the CHART screen as needed; this
portion is also known as a track.
Note that the master track isn't the same as the trip, which is a
record of the specific waypoints, coordinates, and saved points
to which you have navigated.
Track data is saved whenever power is on and GPS position is
being calculated, and even when your vessel isn't moving.
When you're in demo mode, your vessel's true positions are
recorded, not the demo positions.
By displaying one or more of the named tracks on the CHART
screen, you can graphically see everywhere your vessel has
been during the time represented by that particular track. This
feature lets a fisherman, for example, easily retrace the exact
track of a profitable fishing run. You can store any number of
named tracks to precisely record voyages you may want to
repeat.
