Installed June this year, using the Terrova transducer the unit has been good until Fri/Sat.
These are the readings I'm getting. Reboot works for a while, then back to the photo shots,
The unit has no connections loose, any suggestions. Reset back to factory defaults works for a while,
then back to same thing...?? any guru help will be appreciated.

have you tried using another 2d transducer, the us 2 ducer maybe going bad

I see that occasionally when I get cross-talk from another unit.

I'll check into those two ideas, what about the unit, could that be the problem,...is there a test..??

I'm no guru by any means but it looks like you have it set on a dual frequency setting. I dont think it's set right for the universal sonar it the trolling motor. I believe they are 200 Hertz transducer. Again I'm not a guru, and maybe one will be on here with an answer for you. One other thing you might have sensitivity set high if it's not a very hard bottom. Looks like you're getting a double echo in 20' of water.

great idea,...thanks/ jim

If you know someone that has the same unit that is not mounted in the dash or hard mounted on the deck ask them if you could take your head unit and plug it into their wiring. If they aren't having problems and you do with your head there is a problem with your unit (or settings on your unit). If your unit is having problems on their transducer, have them put their unit back on and go to their settings. Take pics of their settings screen and see if you're close to their settings.

thanks for the help. headed to Fork tomorrow for a few days,..I'll check all these things I can.

Sure going to Fork, rub it in. Good luck fishing and I hope you get your unit figured out.
