The "----" reading occurs at water
depths greater than 100 m (from memory) so the "----" display and incorrect deep depth display are essentially the same thing possibly indicating that the transducer is either not sending / receiving a good signal or there is a disruption to this signal along the circuit to the wsi unit.
possibility could be location of the transducer. I had the system that uses the 2 x 42mm through hulls and had a very strange problem with mine related to the speed log in that it absolutely refused to work in one through hull
and would only work when swapped to the other. The depth sounder
happily worked in either. I can only assume it was turbulence causing the problem (and, yes, the paddle wheel
was orientated correctly in both locations!). Perhaps there is something affecting your depth transducer at it's mounting? This is easy enough to test by hanging the transducer over the side if length of lead permits or even just shooting through the hull
in a nearby location if possible with your boat.
