ABSTRACT:
A sight reticle for an archery bow sighting device is disclosed which has a plurality of permanently affixed aiming points spaced at calibrated intervals corresponding to target distances differing by a constant distance. The sight reticle includes a first portion consisting of an attachment screw (1) that attaches at one end to common existing archery bow sighting devices, a second portion (3) attached to the first at the other end of the screw which holds an aiming point carrier (7), and a third portion (7) connected to the second portion that carries multiple aiming points. The topmost aiming point (9) is coaxial with the attachment screw and all aiming points lie on a straight line substantially perpendicular to the long axis of the attachment screw. Rotating the attachment screw about its axis enables the archer to proportionally vary the perceived aiming point intervals in order to adjust the reticle to accommodate any arrow speed.
