Installation Menu
Controls unit settings like Keel Offset, Water 
Speed Calibration and Transducer Type (only 
for components connected to this display unit 
through the blue sonar connector). You can not

Keel 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 keel 
or from the transducer to the water surface. You can use Keel Offset to factor those 
distances into the unit’s depth calculations. 
Accounting for the distance from the transducer to the keel will prevent you from 
striking underwater objects or running aground, which could damage the keel. 
Offsetting the distance from the transducer to the water surface will give you a more 
precise depth reading.
