BASIC OPERATION > REVIEWING AND EDITING WAYPOINTS
Proximity Waypoints
Use the Proximity sub tab to define an alarm circle around a stored waypoint. The
alarm circle can help you avoid reefs, rocks, or restricted waters. You can add
proximity alarms to a maximum of 10 waypoints or on-screen map items, with a
maximum alarm radius of 99.99 nautical or statute miles, or kilometers.
If a proximity alarm circle overlaps an existing alarm circle, the message
“Proximity Overlaps Another Proximity Waypoint” appears. Because the unit
only alerts for one of the overlap points, use caution when navigating in these
areas. If your boat enters a red proximity circle overlap, you are alerted only to
the closest proximity waypoint.
