  • Patent number: 4982503
    Abstract: An archery bow sight, for improving the accuracy of shooting by an archer and reducing cant in the use of the bow, comprises front and rear horizontal and vertical cross-hair sets located within front and rear sights which are mounted on a support member attached to sight holes on the bow. The cross-hairs sets are adjusted so that they are superimposed when the archer draws the bow to the normal anchor point. Shooting pins are provided in the front sight to provide centering points for targets located at various distances from the bow. In use, the shooting pins are centered on the target with the front and rear cross-hair sets perfectly aligned with or superimposed with one another. When this is done, cant of the bow readily may be reduced or eliminated.
