Alarms<br />
This unit has three different types of sonar alarms. The first is the Fish<br />
Alarm. It sounds when the Fish I.D. feature determines that an echo<br />
is a fish.<br />
Another alarm is the Zone Alarm, which consists of a bar on the side of<br />
the screen. Any echo on the chart that appears inside this bar triggers<br />
this alarm.<br />
The last alarm is the Depth Alarm, which has both a Shallow and a<br />
Deep setting. Only the bottom signal will trigger this alarm. This is<br />
useful as an anchor watch, a shallow water alert or for navigation.<br />
Depth Alarms<br />
The depth alarms sound a tone when the bottom signal goes shallower<br />
than the shallow alarm's setting or deeper than the deep alarm's setting.<br />
For example, if you set the shallow alarm to 10 feet, the alarm<br />
will sound a tone if the bottom signal is less than 10 feet. It will continue<br />
to sound until the bottom goes deeper than 10 feet.<br />
The deep alarm works just the opposite. It sounds a warning tone if the<br />
bottom depth goes deeper than the alarm's setting. Both depth alarms<br />
work only off the digital bottom depth signals. No other targets will trip<br />
these alarms. These alarms can be used at the same time or individually.<br />
