Warning forward range and warning depth
Set the warning forward range and warning depth thresholds that
define the warning zone lines shown on the ForwardScan image.
Offset angle
The offset angle is used to fine tune the transducer angle if the
transducer is not installed parallel to the waterline.
If the mounting angle of the transducer is off, the image can be
misrepresented.
The angle can be adjusted from 0 (vertical) to 20°.
Warning:
Adjustments to the offset angle value
should be done with caution. Large variations in the
offset angle value can distort depth data, increasing the
risk of striking underwater obstructions.
Depth offset
All transducers measure water depth from the transducer to the
bottom. As a result, water depth readings do not account for the
distance from the transducer to the lowest point of the boat in the
water or from the transducer to the water surface.
