One of the last times out, I got the transducer cable caught while bringing my trolling motor onboard. I got into one of the wires, so I did what I could to keep the moisture out. It's started acting up and now I'm wondering what to do.

It's the HB 570DI, which I do enjoy. I've since purchased a HB 798 for the console. Now, since it's seems that I may have to purchase a new transducer, I wonder if I should just get another TD for the 798 and just move it back and forth. I didn't think a $300 unit would have a $150 TD, but I guess it does. Best I can tell is that I'd be spending about $30 more of the 798 TD.

Thoughts?
