Alarms
This unit has three different types of sonar alarms. The first is the Fish
Alarm. It sounds when the Fish I.D. feature determines that an echo
is a fish.
Another alarm is the Zone Alarm, which consists of a bar on the side of
the screen. Any echo on the chart that appears inside this bar triggers
this alarm.
The last alarm is the Depth Alarm, which has both a Shallow and a
Deep setting. This is useful as an anchor watch, a shallow water alert
or for navigation.
