I recently had the above fish/depth finder installed by the dealer I bought the boat from. It seems to work "okay", except when I get up to about 30 mph (even though it claims to work up to 70 mph) and then it looses the bottom. But, my question is about the water temperature. It constantly BLINKS at 32 degrees. It's never changed from that. Is there something missing or is it a bad transducer? I don't see any extra wires. Anyone else have one of these and experience anything similar?
