Settings Transducer Keel Offset (-3.5 feet) Keel Alarms Enables alarms and selects alarm thresholds. Arrival, Off Course and Anchor alarms are only available in Advanced mode. Before setting keel offset, measure the distance from the transducer to the lowest part of the keel. If, for example, the keel is 3.5 feet below the transducer, it will be input as -3.5 feet. Temperature calibration Calibrates data from the transducer temperature sensor with data from a known temperature source to ensure the accuracy of temperature information.
