Water speed averaging Averages water speed by measuring your speed at a selected interval of time. Water speed intervals range from one to thirty seconds. For example if you select five 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 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 influences to the measured temperature. Calibration range: -9.9° - +9.9°. Default is 0°. Ú 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 sonar module. The transducer selected will determine what frequencies the user can select during sonar operation. In some transducers with built-in temperature sensors, the temperature reading may be inaccurate or not available at all if the wrong transducer is selected. Transducer temperature sensors are one of two impedances - 5k or 10k. Where both options are given for the same model transducer, refer to paperwork supplied with transducer to determine impedance. StructureScan This feature is automatically enabled when a TotalScan or StructureScan HD transducer is plugged in before the unit has been powered on. It is possible to set a Structure depth offset for the structure transducer. This setting is in the Sonar Settings dialog. SpotlightScan This feature is enabled automatically when a SpotlightScan transducer and sensor is plugged in before the unit has been Software Setup | HDS Carbon Installation Manual 43

Transducer type is used for selecting the transducer model
connected to the sonar module. The transducer selected will
determine what frequencies the user can select during sonar
operation. In some transducers with built-in temperature sensors,
