  • Automatic distance compensating sight and process of sighting
    Patent number: 4167333
    Abstract: A sighting lens has a refraction displacement of the image such that upon selected positioning of the lens on a weapon, such as an archery bow, and using a reference point therewith, a novel sighting procedure for hunting animals can be used which comprises aiming a selected distance below the image of the animal as it appears in the lens. Prisms are included to correct the line of sight which may not be true because of offset mounting of the sighting device. Increments of distance are provided on the lens for assisting the archer in aiming at a distance which is beyond normal shooting limits of that particular sight.
