I was wondering if anyone on here had dealt with this before?
The transducer installation manual mentions that my unit won't work well in boats with "cored hulls".
Is the hull in that part of the bilge on my Mastercraft "cored"?
I've tried to research it, without any luck, and I'm not sure.
Hmmm. maybe you have a bad transducer, because where you described is almost exactly where I installed mine. Mine on occasion gives a inaccurate reading at high speeds when the water is pretty murky. I used a livorsi depth sounder, which I think is like a hummingbird unit.
