I am having no luck with my 570 di on the front of my boat. The transducer is mounted to the trolling moter. It works about 50% of the time. It seems to quit working mainly in shallow water, 10 ft or less and when I use the trolling motor. But it does quit working while not using the trolling motor.

What is does is read the wrong depth and the screen is cluttered. It also may read the right depth but use the wrong depth of water column. The actual depth may be 10 ft and it read that, but it uses 100 ft on the screen and you can't see any structure.

Been on phone twice with Hummingbird. First they had me move transducer wire away from any other electrical wires and change noise filter setting to high. This seemed to help some. They are sending me a filter to install. I sure hope that fixes the problem. The representative stated that other customers are having similar problems.

Is anyone else having similar problems? If so did you get one of these filters and did it work?
