  • Patent number: 8272137
    Abstract: An archery sight device for selectively illuminating fiber optic range markers calibrated to a specific distance, a selector switch and a range indicator display for accurately aiming and releasing an arrow at a designated target. The sight device comprises a housing that attaches between the upper and lower limb of an archery bow, and provides a sight window with a plurality of fiber optic pins with illuminating tips. A selective pin or set of pins is illuminated at a time, corresponding to a distance indicated by a digital display for the user to reference. A selector switch extending from the device and attached to the bow allows the user to cycle through pre-calibrated distances for a specific bow, while a range finder device may be incorporated to accurately measure the distance to a target and adjust the display and chosen illuminated pin as required.
