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. Before setting keel offset, measure the distance from the transducer to the lowest part

Temperature calibration
Calibrates data from the transducer temperature sensor with data from a known temperature source to ensure the accuracy of temperature information.
Reset water distance
Resets the Water Distance value to zero.
Transducer Type
Selects the transducer model attached to your unit. You must select the correct transducer type to get the best sonar performance from your unit.
