I just picked up a new marcum and was very happy with it the first two times I used it. Then the third time I had it out it started to flutter or jitter quite a bit. What I mean by jitter is when I would adjust the gain to where my lure is a fine yellow line, the line would bounce back and forth between two or three lines up and down,and so would the red fish marks. Everything on the dial would jitter more than I can remember it doing the first two times I had it out. I tried everthing to get rid of it from adjusting the gain, raising and lowering the ducer, putting on the IR, turning it on and off. Since I am new to sonar maybe this is normal? It was very annoying and I am wondering if I have a faulty unit. I was fishing on LOW the day it gave me problems and there were no other people by me.
