  • Patent number: 8739419
    Abstract: A targeting system for a bow is disclosed. A laser rangefinder is offset from a designated pin on the bow sight such that a theoretical line of sight for the designated pin intersects with a rangefinder laser beam emitted by the laser rangefinder at a preset distance. An adjustment mechanism is provided that permits the position of the laser rangefinder relative to the bow to be adjusted such that the rangefinder laser beam and a user's actual line of sight along the designated pin intersect at a target located at the preset distant. The designated pin permits the user to aim the laser rangefinder at a selected target and adjust an elevation of the bow to an angle corresponding at least approximately to a range to the selected target displayed by the laser rangefinder. In one embodiment, the rangefinder laser and the bow sight form a unitary bow sight assembly.
