Dosn't matter if I'm sitting still or if I let the wind push me back a little. When I push spot lock, the motor goes almost on high and goes about a foot or 2 off, then goes back to where I pushed spot lock. Its a little over 2 years old and It just started doing this. Recalibrated the trolling motor and antenna by driving around in 2 full circles and it still does it. Anybody have this issue or recommend a fix?

My new ulterra does the same thing. I just thought it was normal. After it settles it will stay on the spot just fine.
