ABSTRACT:
A bowsight for attachment to a bow. The bowsight has a crosswire frame which is supported by a bracket held to the bow. A pin slide is formed in an inner frame member and has a cylindrical opening. The pins can emit light and are mounted in transparent discs which slide into the cylindrical opening and which are tightened by an Allen screw against a slot in the disc, thereby expanding the disc against the side of the pin slot. The transparent disc gathers surrounding light and transmits or directs the light to the light-emitting pin. A lens or a light-emitting source can be positioned in the cylindrical opening to surround the transparent disc with light. The crosswire frame may be incrementally moved up and down with respect to the bracket by locking a spring-loaded ball bearing in any one of a plurality of detents in the frame. The spring-loaded ball bearing may be forcibly engaged so that the spring is completely compressed thereby locking the ball bearing in a chosen detent.
