This derivative of the Carolina Ticker is designed specifically for Carolina Rigs. The large recessed cavity on one side rests over the knot, directly onto the swivel, protecting the knot from potential damage cause by the bead or sinker. Fish attracting sound is also produced from the strikes of the sinker of bead against the Pro Ticker. Available in pack of 10 sinkers only or a pack of 7 sinkers and 7 beads.
