ABSTRACT:
A sight apparatus for an archery bow which compensates for both the distance to a target and the elevation of the target. The sight apparatus includes a range finder mechanism and a pendulous sight. The range mechanism and the pendulous sight are operatively connected such that the setting for the range to a target positions the pendulous axis. The pendulous sight has a sight element which is suspended from the corresponding pendulous axis to provide a point of aim at the target. The range mechanism includes an adjustment arm which is pivotable to a known or estimated distance. The range mechanism also includes a pair of bracketing pins wherein one of the bracketing pins is movable relative to the other bracketing pin along an arc shaped travel path for bracketing the target and providing a range setting determined from the size of the target.
