Slab,I turn mine up high on Max mode and could see fish I could not see on DI ,it was too windy to fish there much but tried it ,was hard to keep jig under sonar with that much wind,did notice that I could not use fire line because it pick it up all the way down when I jig it look like 30 jigs on one line,don,t use fire line much but it already had bait I wanted to use.
