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.
Warning:
Adjustments to the transducer angle value should be done with
caution. Large variations in the transducer angle value can distort depth
data, increasing the risk of striking underwater obstructions.
Depth offset
This is a value that can be entered on the Echo Installation page to make depth readings
relate to any point from the water surface, to the deepest point of the vessel. Below are some
alternative ways in which the offset can be entered:
Before setting the offset, measure the distance from the transducer to the lowest point of the
boat in the water or from the transducer to the water surface.
A) For depth below keel: Set the distance from transducer to the bottom of the keel - this
should be set as a negative value. For example, -2.0.
B) For depth below transducer: no offset required (the offset is set to 0).
C) For depth below surface (waterline): Set the distance from transducer to the surface - this
should be set as a positive value. For e0.5.
