Waterline Offset
You can get a more precise measure of water depth by using waterline offset, which takes into account the distance from the transducer to the waterline when calculating depth.
Before setting waterline offset, you must measure the distance from the transducer to the waterline on your boat. If, for example, the transducer is 1.5 feet below the waterline, it will be input as +1.5 feet.
