Configuring the Recording Interval of the Track Log
You can indicate the frequency at which the track plot is
recorded. Recording more frequent plots is more accurate but
fills the track log faster. The resolution interval is recommended
for the most efficient use of memory.

Boundaries
Boundaries allow you to avoid or remain in designated areas in
a body of water. You can set an alarm to alert you when you
enter or exit a boundary.
You can create boundary areas, lines, and circles using the
map. You can also convert saved tracks and routes into
boundary lines. You can create a boundary area using
waypoints by creating a route from the waypoints, and
converting the route into a boundary line.
You can select a boundary to act as the active boundary. You
can add the active boundary data to the data fields on the chart.
