ABSTRACT:
Stereoscopic sighting apparatus includes a support plate supporting a pair of sighting members of identical open loop configuration in laterally spaced side-by-side relation to one another at a distance approximating the spacing between a users eyes for generating an overlapping coincident central image of the sighting member when viewing a distant target with both eyes open. A plurality of distance indicator pairs are supported by the sighting members for enabling the user to compensate for distance to target. The sighting members and distance indicators provide an unobstructed view of the target in the coincident central image while maintaining accuracy. Side-mount mounting hardware enables the apparatus to be mounted to a longitudinal midsection of a bow.
