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, because the Crappie Cork comes with the bobber stop on the cork already and has a special, small diameter insert that 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. Suggested lure weights are printed on the float making selection easy. The Crappie Cork's plastic line-friendly insert is designed to grab the bobber stop without needing a bead..
