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

can add the active boundary data to the data fields on the chart.
