I think I've printed out some recommended 'things to try' that maybe Rickie has in a sticky, or else I'm thinking of LWinchester on bbc. Contrast and brightness will be the things you play with. I expect to change my settings at each lake I go to, variables with different waters, different bottoms, etc. Find a palette you can see best under that day's conditions (may change) and go right back where you spoke of..a place of known cover and structural changes. Don't fish, just try to learn your unit at this point. Adjust one of the two elements until things start popping for you. Know where you start at so you can return if you aren't happy. If you get lost you get confused and frustrated. Contrast may very well be the bigger ticket for you, but if not then it may take a combination. It sometimes takes a bit to get really comfortable with them, I'm happy with my displays. I agree that for sv I'm looking for cover or structural differences. If I see soft targets so much the better. 2d for that and then dv. Freq's can matter also. When you set contrast and brightness on sv and dv I think they are independent one from the other and also per freq
