Sonar transducer calibration Sonar transducers should be calibrated to ensure that accurate readings are displayed on the MFD / chartplotter. ContentsDepth transducer offsetDepth is measured from the transducer face to the bottom (e.g.: seabed). An offset value can be applied to the depth data so that the displayed depth reading represents the depth reading taken from either the keel (negative offset) or the waterline (positive offset).Configuring transducer settingsFor systems with a transducer connected, as part of setting up your system for the first time it is important that you correctly configure your transducer.Parent topic: Getting startedPrevious topic: Identifying enginesNext topic: Performing a settings or factory resetParent topic: Fishfinder appPrevious topic: Fishfinder sensitivity controlsNext topic: Fishfinder settings menu
