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 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 the alarm.
The last alarm is the Depth Alarm, which has both a Shallow and a Deep setting. Only the bottom signal will trigger this alarm. This is useful as an anchor watch, a
Depth Alarms
The depth alarms sound a tone when the bottom signal enters water more shallow than the shallow alarm's setting or deeper than the deep alarm's setting. For example, if you set the shallow alarm to 10 feet, the alarm will sound a tone if the bottom signal is less than 10 feet. It will continue to sound until you steer your boat into water deeper than 10 feet.
The deep alarm sounds a warning tone if the bottom depth is deeper than the alarm's setting. Both depth alarms work off digital bottom depth signals. No other targets will trip the alarms. These alarms can be used at the same time or individually.
