Proximity Waypoint List
The ‘Proximity’ submenu of the Points tab lets you define an alarm circle around a stored waypoint
position, and can be used to help you avoid reefs, rocks, or restricted waters. Up to ten waypoints may
be listed, with a maximum alarm radius of 99.99 nautical or statute miles or kilometers. If a proximity
alarm circle overlaps with an existing alarm circle, the message ‘Proximity Overlaps Another Proximity
Waypoint’ appears. Since the unit only alerts for one of the overlap points, use caution when navigat-
ing in these areas. If you enter an alarm circle overlap, you are only alerted to the closest proximity
waypoint.
