Settings Transducer Keel Offset (-3.5 feet) Keel Alarms Enables Shallow alarm and allows you to select the alarm threshold. The Shallow alarm sounds an alarm when your vessel enters water shallower than the selected shallow threshold. 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 readings from the transducer temperature sensor with data from a known temperature source to ensure the accuracy of temperature information. Units Allows you to select the unit of measure used by your unit. Simulator Used to simulate on the water activity. Reset water distance Reset Water Distance to zero. 19
