    I have an autohelm tridata log and depthsounder.

    The depth function is intermittent.

    I have changed the transducer which seemed to fix the problem for a time but
    it has reoccurred.

    Any ideas?

    Algae, barnacles or other stuff growing on face of transducer?

    No, underside has been checked.

    I was thinking of electrical failures which have been seen before.

    I had same problem, in my case it turned out to be the instrument.

    Same here, but with a ST40 Bi data instrument.
    Ramarine support suggested I re-configure it, which I tried, but to no
    Eventually it did not work with either the speed or the depth transducer.
    The transducers work fine if I substitute a different instrument.
    By the time I got another instrument to test the transducers with, the
    original was just out of warranty.
    It works fine as a Seatalk repeater.
  6. I had the same problem on my ST50 tridata during my holiday last week.
    I opened the device and noticed it was very wet inside.
    Just clean the PCB, put it together and try again.
