If I might add my two cents, I agree with everything the Sk8man has said, and I would like to add to it. Good elecronics is vital in finding ice crappies, i.e Vexilar, Marcum, etc., as they almost always suspend in the water column. I have had my best luck with glow jigs in reds and oranges, tipped with small fathead minnows, under floats. Waxworms work on an actively jigged rod, as well. The electronics not only let you know where to set your float, but can also help by showing you what mood the fish are in. When the fish marks move quickly up to your bait and hit fast, they are very aggressive, and so on. Hope this helps. Thanks.
