Fishfinder Transducer Calibration
Your fishfinder transducer must be calibrated correctly to achieve accurate depth readings.
The multifunction display receives the image from a DSM which processes sonar signals from a transducer mounted in the water. If the transducer is equipped with a speed paddle wheel and
calibrate the transducer(s) by applying offsets to depth, speed and temperature. As these settings are held in the DSM and relate to the transducer, they are applied
