Bill See if your chandlery might loan you a transducer for an afternoon. I once purchased an ST40 bi-data that had erratic depth behavior and on loan of a spare transducer had same behavior. It was the control head
In 2014 we purchased i50/i60 tri pack. Occasionally the depth would start to wander from its correct reading of 40-50 ft to a depth of 2 feet and then wander back. Often would see LAST as well. The source of the trouble was that my speed and depth transducer cables were run as a bundle and ran in a bundle alongside power lines. I moved the depth transducer cable away from the electrical wires and problem went away. Also when in very deep water (something more than 400 feet will always show --- or last).

Boat was splashed yesterday. The depth display reads LAST and three dashes where the depth should be displayed. Obviously, it is not getting the information from the transducer. Raymarine's technical help consists of: "buy another transducer and plug it in to see if you have a bad transducer or cable". Sadly, that is more troubleshooting information than they provide in the manual! I just called Raymarine tech support and talked to one of their installers. That was all he had for advice. I was looking for measurements I might take. Resistance between the three leads? Voltages? Waveforms? I have good test equipment and know how to use it. The guy at Raymarine is an installer, not an electronics tech. Does anybody have even some basic values to test the transducer?
