TIP TRIP: Most ice anglers open up a half-dozen holes, then leave "tip-ups" in the ones they aren't actively fishing. When a fish bites, the tip-up raises a flag and the angler comes rushing over. Instead of spending $100 on a half-dozen tip-ups, spend $10 on quill bobbers. Build a small ice pile next to your hole, attach a bobber to your line, and prop it on top of the ice hill. The quill will be visible from several yards away and will fall down when a fish hits.
