lowrance sonar problems

[sparky27]

I Bought a new lowrance lxc-17 in 2007. It has worked great up until my most recent trip. The problem is when I troll at 2-5 mph the sonar wont read the depth. If I am in no motion the sonar works great. Any advive or information on fixing my problem would be much appreciated.

If it happens just when you run the trolling motor maybe you are having electrical interference or maybe your transducer got bumped and is at a bad angle. Thats what comes to mind for me.

Probably just as stated, your transducer is either tipped to far up or to far down. If that does not cure your problem, you will probably need to replace the transducer.

Refer to your manual's transducer mounting section. Did you try manually increasing the gain? After doing the above, does it read bottom better in shallow water. You probably have a bad transducer.

I had the same problem with my 102c. Tried to adjust the transducer but nothing worked. Called lorance since it was under warranty and they sent me a new transducer. Put it on and it works great now.

Sounds like they may have a bad batch of transducers since I have seen many post with the same type of issues. Not saying it will be YOUR fix but it worked for me.
