Abstract: Certain embodiments include archery bow sights which incorporate pin adjustment mechanisms which can be set to automatically arrange sight pins in appropriate proportional spacing for various target ranges based on the spacing of two initial points. In certain embodiments, a first pin on an archery bow sight is calibrated at a first reference distance to define a first reference point on the sight. The bow and sight is then used at a second reference distance to determine and align a second reference point for a second sight pin. As aligned, the mechanism controls one or more additional sight pins to correspond with additional reference distances. In certain embodiments illustrated herein, the pin adjustment mechanism arranges pins within a vertically aligned orientation.
