Abstract: An adjustable counterweight pendulum bow sight which is fitted with a sight ring having monofilament crosshairs and optionally provided with a source of black light or alternative target enhancing devices such as fiber optic systems, for illuminating the sight ring area under conditions of low lighting. The pendulum bow sight is mounted to a bow in pivoting fashion and includes a pendulum bracket fitted with adjustable counterweights of various design, facilitating convenient and accurate sighting of the target in a direct line of sight, regardless of the elevation of the hunter. The sight ring in the pendulum bow sight is mounted on the pendulum bracket, which is pivotally and adjustably attached to a frame mounted on the bow. The pendulum bracket and thus, the sight ring, may be stabilized by operation of a stabilizing pin and supported in a limited pivoting configuration with respect to the frame, by means of a pendulum bracket support.
