I know there are a ton of threads on this which I have read but wanted to check for any new thoughts.
I have a glued on p79 airmar. Garmin 5212. No glycol cup.
Sonar has worked reasonably well up until now. Not great detail but pretty good bottom holding.
(Ok for 3 years. Occasional would have drop outs. )
This weekend was a little choppy and the boat banged into a few waves. - nothing crazy.
Sonar stopped working at some point in the trip. I didn’t notice the exact moment. Do not know if banging was the cause. Now it shows typical surface detail as it hunts for the bottom in full auto for all settings. It never finds bottom. Just largely a blue screen. With the occasional color pixel at a random location.
I’ve tried messing with manual settings such as gain to try and force it to see the bottom again. No bottom detail ever surfaces.
I am sitting in the marina at low tide - I’d guess about 12 of water below me and I can see the bottom. Sonar can’t find a damn thing.
Checked the transducer and it’s still glued down well.
Some questions.
1. Where does the sonar cable run to? I assume it’s hard wired to the garmin rather than nmea network. But I don’t see that cable on the back of the 5212? I want to check the connections
2. Can a transducer go bad?
3. Any recommended settings on the sonar to troubleshoot?
4. Is the only way to reset a transducer to turn off the house power?
5. Other ideas?
