I have this unit mounted on a 16 foot flat bottom on the transom. I followed all of the mounting recommendations for the unit. My problem is... When there is chop on the lake, my graph seems to read the bottom contour of the lake like a heart beat monitor... In 2d and DI both... Is there any way to get rid of that or is it simply just the size of my boat?
If you mean its curvy or wavy then no way to change it. It is the rocking and up & down motion of the transducer. It happens even on larger boats.
EZFISHN is correct ... it's the bounce of the boat/transducer creating the wavy image lines. Don't matter what size boat, if it's bouncing up & down it is changing the distance the sonar ping has to go, from the transducer to the bottom or any obstructions between them.
I have a Lowrance Elite 5 DSI unit, trolling motor mounted, and see the "waves" in my images anytime I'm in choppy water. Such as in this instance, when I was downscanning a brushpile :

The only "solution" to this is to scan in calm waters ... otherwise, the nature of the way a downscan/2d unit works is going to produce the wavy images.

That's what I figured it was. CrappiePappy, that's exactly what it looks it while wake is present. I sure appreciate the feedback from both of you.
CrappiePappy: Do you have any issues finding PVC brush on DI? I can see them on 2D, I think, but I can't really get a good reading on DI... I need to take some screen shots and put them on here.
