Water speed calibration
Water speed calibration is used to adjust the speed value from the paddle wheel to match the actual boat speed through the water. Actual speed can be determined from GPS speed over ground (SOG) or by timing the boat over a known distance. Water speed calibra- tion should be performed in calm conditions, with minimal wind and current movement.
Water speed averaging
Averages water speed by measuring your speed at a selected inter- val of time. Water speed intervals range from one to thirty seconds, e.g. If you select five seconds, your displayed water speed will be based on averaging over 5 seconds of sampling.
Water temperature calibration
Temperature calibration is used to adjust the water temperature value from the sonar transducer to match the data from another temperature sensor. It may be required to correct for localized influ- ences to the measured temperature.
¼¼ Note: Water temperature calibration only appears if the transducer is temperature capable. Check transducer type selection if this option should be available.
Transducer type
Transducer type is used for selecting the transducer model that came with your unit. In some transducers with
