Note:
To receive Critical Zone alerts, enable ForwardScan alarm
in the Alarm settings dialog. For more information about
enabling alarms, refer to Alarms.
Transducer angle
We recommend installing the transducer vertical to the waterline. In
cases where that is not possible, the Transducer Angle setting helps
offset the difference between the transducer angle and the
waterline.
The angle can be adjusted from 0 (vertical) to 20 degrees.
