Customer Question

Have Lowrance Mark 4. Have been pleased with it except for one thing. Even when it was new it goes crazy saying that water depth is 2.7 to 3 feet deep. I know water depth is 80 to 150 deep. When it goes into this crazy mode nothing I can do seems to correct the problem. Sometimes that condition lasts only a few minutes and other times it can last for hours.

Hi good morning, Im sorry to hear about that.

This sounds like a bad transducer at the bottom of the boat.

If it leaks at all at any time, you will have this problem. Its easy to replace and the new one also comes with instructions.

How old is your Lowrance?

Thank you

Tech Michael
