Max mode constantly is hurting your fishing more than you know.
In max mode, your unit will not filter any echo returns. Because of that the screen is cluttered with color, arches are generic in size. The top of the screen has a heavy red colored bar that occludes the surface.
In clear mode, your sonar returns are filtered to remove junk and misc. echoes. The top of the screen is clear (if a thin line is there set surface clutter to 2 and that will remove the line.) Echo returns are filtered and a large arch represents a large fish, a small arch a small fish.
If your units is only showing fish while on Max, your settings need tuned.
