  • Solo plane pin head bow sight
    Publication number: 20010032393
    Abstract: The bow sight of the present invention includes at least one pin that doglegs from one of a multiple set of tracks to align the doglegged pin's head in a common axis with the pin heads of other pins that are positioned in other tracks. Each pin of the bow sight includes an aperture through a pin head that is aligned such that all fiber optic elements received in those apertures align with the archer's line of sight. The pin guard of the bow sight is circular and forms an integral portion of a proper sight picture for an archer.
