Proximity Waypoint List
The Proximity list allows you to define an alarm circle around a 
stored waypoint location, and can be used to help you avoid reefs, 
rocks, or restricted waters. Up to 10 waypoints can 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, a “Proximity Overlaps Another Proximity Waypoint” 
message appears. Because the unit only alerts for one of the 
overlap points, use caution when navigating in these areas. If you 
enter an alarm circle overlap, you are only alerted to the closest 
proximity waypoint.
