With crappie season hitting high gear I have been reading a lot of magazines on catching crappie. In the articles they say to use your fish finder to locate the fish. This may be in surprise areas that dont have classic structure. This also may explain some of the mystery of getting on these fish. What is a good reliable fish finder that will show you the fish? I dont have a lot of confidence in my eagle 1000c, and am about to buy one for the bow, anyone have fish finders dialed in?
