 Tip-up (ice fishing)

A tip-up is a device used while ice fishing to suspend live or frozen bait at a set depth through a hole drilled in the ice with an auger, and detect when a fish strikes, without having to be in contact with this piece of gear.When a fish does take the bait, a flag "tips up" or the flag can "tip down" to signal the angler that a fish has taken his bait.
