ABSTRACT:
A bowsight is provided for an archery bow including a support bracket for attachment generally parallel to the length of the archery bow. A plurality of sights are connected to and are longitudinally spaced along the support bracket. Each of the sights defines an outer longitudinal height and a smaller inner longitudinal height. The outer heights are successively smaller from sight to sight. Each of the outer longitudinal heights are positioned so that the bow will be properly aimed at a target when the outer longitudinal height of any one of the sights equals the apparent vertical height of the target. The inner longitudinal heights are successively smaller from sight to sight in the same direction as the outer heights become smaller. Each of the inner longitudinal heights are of a dimension so that the bow will be properly aimed when the inner longitudinal height of any one of the sights is equal to the apparent vertical height of the target. The bow is moved to place the target between that sight having the equal inner longitudinal height and the next smaller sight for proper aiming; thereby reducing the number of sights for a given number of target distances.
