Abstract: A rangefinder scope crossbows and other firearms includes an emitter assembly for transmitting radiant energy toward a target, a first collimating lens assembly for receiving and collimating the reflected radiant energy, a prism assembly optically connected to the first collimating lens assembly for receiving the collimated reflected radiant energy, and a receiver assembly in optical communication with the prism assembly for detecting the radiant energy reflected by the target to thereby calculate a distance between the rangefinder scope and the target. A third collimating lens assembly associated with the emitter further increases accuracy of the scope.

Abstract: An archery sight for use with archery bows having different draw weights is provided. The archery sight includes a plurality of sight pins for demarcating a respective plurality of different target distances, with at least some of the sight pins being gang adjustable for accommodating the different draw weights. An adjustment member is movable along a first direction between first and second positions reflective of first and second draw weights, the adjustment member has a plurality of travel pathways being operably associated with the plurality of sight pins to move the sight pins along a second direction different from the first direction so that movement between the travel and the sight pins causes the sight pins to simultaneously move in a second to thereby demarcate their respective target distances for the different draw weights.
