Turn surface clairity to medium. Helps get rid of a lot of junk on your screen. Then put the color palate in ice view. You'll have to play with sensitivity and contrast until it's to your liking.
I run a elite 7 in split zoom mode and try to,make my tungsten jig with wax worm a black line with slight blue in it also. That way there is good separation when the fish gets close to the lure.
Hope that helps
