I didn't change transducers or the sounder. They're the same. To be honest, I don't know what line of Signet it is. I'll check that out. But I believe you're right about the solder at the disconnect fitting. The sounder powers up just fine. Is it possible/advisable to swap out coax cable on these things? It's my understanding that you don't mess with the cable.... but I'm not 100% on that....

I'd be checking that that connection at the sounder is fully plugged in, maybe even disconnect and reconnect it and have a look at it... You can thread the cover off and check the connections inside easily enough... Beyond that try to visually inspect the coax where you can looking for nicks or breaks in the cable.

It is usually best not to disturb this type of cabling but it's not working now so maybe there's not so much to lose by attempting to replace the cable as a check.

I'll check the connection. If I had to guess, I'd say the heat gun may have zapped the transducer. Then again, one of the yard hands was certain that it wouldn't, and he's been pulling these things out of hulls for years now.

I'll report back...

Hey Hog,
I bought a cheapie depth sounder after my old one was taken out by lightning and bedded the transducer in epoxy. It has been working fine for about five years now.
What I did was make a little pool using clear silicone and filled it with epoxy.

Knotty,
How are you?! If I can't fix the connection, I'll be doing the same. How are things down in St. Pete? I'll be based out of PC in a few weeks.... I'll hopefully be getting down your way in the late fall....

I'm another successful shoot-through transducer user. Like BarryL, I was going to just test with the wax, but the transducer was stuck in so well with it, I left it alone. In my case, the transducer was meant to shoot through and not be mounted in a thru-hull.

Hog,
Been okay. Business is better this year especially since we got the boom truck.
Look us up when you get down this way.

Likely, you did not use MEK in your efforts...it kills transducers.

My formula for living is quite simple. I get up in the morning and I go to bed at night. In between, I occupy myself as best I can.

A zip-lock bag of water is easily used to test the location an effectiveness of sounding through the hull. Simply place the bag against the clean inner hull surface and nest the transducer against it for the test. After finding our good location we epoxied our transducer in place. Take care and joy, Aythya crew
