With the proper amount of weight, the cork floats on the lateral line, allowing you to detect even the lightest of bites. There is no need to purchase beads and bobber stops, anymore! The Crappie Cork comes prepared with a bobber stop on the cork. A small diameter insert grabs the bobber stop, so no beads are needed! Simplicity and brilliant innovation make this a staple for every tackle box. The spring on the bottom stem allows for fixed float rigging as well. Thill Crappie Corks are produced in guide-tested, hi-vis colors and sizes. Even suggested lure weights are printed on the float, making your selection an easy one.
