Spare Wheel for the Optimizer King Pin Single pin sight.

This solves the problem of having to re-sight your bow each time you swap form broadheads to field points. Now, simply have two sight wheels, one with a yardage tape for arrows setup with broadheads one with a yardage tape steup for field points. Then, wave goodbye to resighting he bow, or having 2 sets of sights for each bow. Simply, swap the wheel on your optomozer sight and you're away and shooting.
