Patent attributes
A peep sight is a tubular element installed in a bowstring. When drawn, the natural twist of the bowstring may fail to align the peep sight with the other sighting structures on the bow. The invention provides a simple, low-cost, and easily installed bead which, when inserted into a bowstring in the vicinity of the peep sight, may be easily adjusted to bring the peep sight into proper alignment. Once properly adjusted and secured to the bowstring, the inventive peep tuner acts to reliably and repeatably counteract the change in helical twist of the bowstring strands and bring the peep sight to its desired orientation when the bowstring is fully drawn. The bead may also be installed elsewhere along the bowstring as a draw timer to take up excess bowstring length which would pay out unequally during a draw if left uncorrected.
