Well. I hooked another unit up and had the same results: 6 ft depth and only an accurate temp reading. Tried the transducer that came with the unit and still had the same result. I checked all the us2 cable connections including the one inside the head and they are fine. Next, I unwired the depthfinder from the trim and ran wires to the fuse box under my console and STILL nothing. I ran to radio shack and picked up two ferrite chokes and put them on the power cord. Now i can see my hand, tongue of the trailer, etc. on the unit. However, nothing seems to work when using the us2 transducer. Ive decided that it's shot. I still have some problems though or they seem to be problems anyway. Clear Mode doesn't seem to pick up anything while Max does, I can't pick up much of anything with the 83khz beam, and now my depth only reads 0.6 feet. Are these only problems because the transducer isn't submerged? I know it's detecting my hand underneath and i can hear the sonar clicking, but no depth change. My next plan is to order a puck from humminbird and mount it on my trolling motor.

I think you are B Bill. You have to test sonar with the transducer in teh water Carl.

After finishing yard work i had a chancr to get on the water and fiddle with the depthfinder. My hunch was right: the us2 is shot. The transducer from humminbird works like a charm, though. I'm still not sure what a ferrite choke does, but two around the power cable were the ticket. Do y'all know if humminbird exchanges transom mound transducers for trolling motor pucks, or will they just send a mounting bracket for my tm? Thank y'all very much for all the help. Good fishin'.

Carl3of5,
That has to be a new and unused/mounted transducer to qualify for the transducer exchange program:
