I put a x-27 on my front trolling motor last week. I keep getting false depth readings when I get in the weeds anything below twenty feet it seems to jump around alot. I talked to lowrance and they are going to send a different transducer. I tried many things and I don't think that is what's wrong but will see. Has anyone else had similar problems, I have a tourney this weekend and might have to put the old graph back on.
