ment, divide the SOG by the paddlewheel speed, and multiply the product by 100.
Calibration range: 50-100%. Default is 100%.
Water speed averaging (echosounder transducer)
Averages water speed by measuring your speed at a selected interval of time. Water speed
intervals range from one to thirty seconds, e.g. If you select ve seconds, your displayed water
speed will be based on averaging over 5 seconds of sampling.
Calibration range: 1-30 seconds. Default is 1 second.
Water temperature calibration (echosounder transducer)
Temperature calibration is used to adjust the water temperature value from the echosounder
transducer to match the data from another temperature sensor. It may be required to correct
for localised inuences to the measured temperature.
Calibration range: -9.9° - +9.9°. Default is 0°.
¼ 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 connected to the echosounder
module. In some transducers with built-in temperature sensors, the temperature reading may
be inaccurate if the wrong transducer is selected from the transducer type menu.
