I frequently get these vertical lines on my display when I deep bottom fish. Take a look at the bottom lock side of this screen shot. This shot was taken in 124 fathoms, or 744 feet. 1971F using a 260 transducer. Settings: LF, gain set to 70, TVG was max, Interference setting was off, clutter at 50, erase weak echos at 18, and display speed set at 4/1.
I'm thinking this has something to do with my display speed? Should I be displaying slower when in deep water?
