WAYPOINT ZONE ALARM
The zone alarm sets a circle of a specific radius around any
waypoint. If the boat should drift INTO the predetermined
radius the alarm will sound. This is very useful when
attempting to remain near to a specific waypoint but without
getting too close, for example, a wreck particularly good for
fish. The GPSPlus display allows ten zone alarms to be set.
These could be used to create a barrier or exclusion zone
as shown in the example below. Press any key to silence
the alarm.
