SD 50+ depth calibration

That isn't correct. The depth transducer is made up of elements that output and receive the sonar signal. If you are noticing decreased performance, this is due to the elements inside the transducer are degrading or you are losing elements. The recommended course of action is replacing the transducer. Current instrument Depth Transducers are compatible with the ST50+ Depth displays. You will need to cut the transducer connector off the ST50+ display, then remove the spade connectors off the current depth transducers and splice color for color to connect.
