    1197: Interference or bad transducer?



    This is a pic is from my 1197 off my trolling motor transducer. The trolling motor wasn't spinning when pic was taken. The motor is a minn kota maxum 65. When I switch the 1197 with my 998 at the console it has a great image but the 998 will have theses lines. I've done all of the steps to eliminate interference. Could this be a bad transducer? thanks for advice.

    were you pinging on other unit or near another boat? If you were stopped and TM not powered then shouldn't be the TM.

    Yes. I had my 998 at the console running with the sonar on. The transducer for it is on the transom.

    Try turning sonar off on the console unit and see if it goes away. Probably getting some crosstalk

    That image looks like from a 800 and 900 series with the left side readouts. The 1100 series has them on the bottom.

    You are correct. I took the pics a while back and have switched the units around and had the card in both. The lines were on both units while they were on trolling motor mounted transducer.
