It may help you if you still trying to find the best setting of humming fish finder
Favorite #1 Full-Screen Map. Usually, first thing in the morning I am trying to get to a spot. If it’s a lake I’ve fished before or one I have a map for, the full-screen map will help me get there quickly without having to guess. This is especially helpful in the dark.
If you don’t have the map option on your unit, I’d recommend full-screen SI or DI, depending on your unit.
Favorite #2 Down Imaging + Side Imaging ( DI + SI ). I probably use this setting more than any other. Anytime I am scouting an area or moving through an area I suspect has fish, I’ll have this screen on. I also will use it if I am wanting to fish a particular brush pile or underwater structure.
Favorite #3 2D + Down Imaging + Side Imaging ( 2D + DI + SI ) . This last setting I use when I have a lot of debris in the water or a lot of grass that is making it hard to see the density of the bottom and contours of creek channels.
