So the Helix 7 on the bow of my boat I'm having some issues with. It will work fine for a while then it will all of a sudden read depths of 700, 800 or whatever depth and you might be in 20 foot, and it takes a while for it to go back to normal.
I tried turning it off then back on again and it makes no difference.
I have noticed it also when pulling the trolling motor up and moving them when it goes back down it dont want to work. But it will do it while your just fishing running the troller
Does this sound like a bad transducer?
