Humminbird 788ci problem

My bow unit is a Humminbird 788ci, and has been giving me problems with showing correct depth. It has been getting stuck on 0.6 ft most of the time. I was told a couple of things to try that didn't solve the problem. I tried restoring default settings, and that seemed to work at first but then went right back to 0.6 ft. I also tried lowering the surface clutter setting and that didn't work. Anyone else had problems like this?

Is your transducer bad?

Not sure Mark. That's the next step if I can't get it figured out.

I had a similar issue. It ended up being a bad transducer.

Thanks Mark. I went ahead and ordered one to mount on trolling motor. Hopefully that's the fix, and it's not a bad unit.

I have the same Unit on the Bow of my Boat. it works good but if i leave it on to long it will shut off by it self.... not sure if it has a timer on it or what.
