Depth offset
All transducers measure water depth from the transducer to the
bottom. As a result, water depth readings do not account for the
distance from the transducer to the lowest point of the boat in the
water or from the transducer to the water surface.
• To show the depth from the lowest point of the vessel to the
bottom, set the offset equal to the vertical distance between the
transducer and the lowest part of the vessel, A (negative value).
• To show the depth from the water surface to the bottom, set the
offset equal to the vertical distance between the transducer and
the water surface, B (positive value)
• For depth below transducer, set the offset to 0.
Water temperature calibration
Temperature calibration is used to adjust the water temperature
value from the sonar transducer. It may be required to correct for
localized influences to the measured temperature.
