The Beaver Dam Round Tip Up sets the bar for the ultimate round plastic tip up. Beaver Dam has taken a 10" round plastic base and added 1" of foam to the bottom to insulate your fishing hole. They also added the legendary main assembly to give you the smoothest and best built tip up. This Round Tip Up is as smooth as the original Beaver Dam series. Walleyes don't stand a chance with the Beaver Dam Round Tip Up over their heads.Features10" Round plastic base1" Foam insulationGreat for walleyes
