I need some help trying to locate crappie. I was on the lake all day Sunday and came up with only 2 and about 8 bass. I just bought a fish finder but am still learning how to use it. I did go over some vegatation in 5-7 feet of water and the fish finder was showing about 20 fish but when I looked down I didn't see any fish not even bait fish. I don't want to rely on the unit to find fish just to help locate structure and depth. I was wandering during the day where would be good areas to find crappie.
