Beaver Dam's New Arctic Circle thermal tip-up sets the bar for the ultimate round plastic tip-up. We have taken a 10" round plastic base and added 1" of foam to the bottom to insulate your hole. We also added our legendary main assembly to give you the smoothest and best built tip-up money can buy. This tip-up is as smooth as the original Beaver Dam wood tip-up. Walleye's don't stand a change with this tip-up
over their heads!
