Transducer wrecked? CA200b-8b

[Campdog]

Hi brains trust,
Tried out this second hand tranny today and it looked to get a reasonable reading for the first few mins of use, then got these diagonal lines showing. I’m pretty sure the Tap settings are correct. Any ideas? This was stationary.

Disconnect the transducer and put the FCV295 in Demo mode and see what it looks like. If those lines are repeating it appears to be either transducer or power induced interference.

Thanks titanic. Here’s a few pics with the tranny disconnected. Demo mode and just running with no tranny……..

The unit looks fine, transducer appears to be severely noisy and ringing (still vibrating when it is supposed to be listening).
