ABSTRACT:
A sighting device for use on an archery bow has one or more light gathering fibers that are substantially parallel to the archer's line of sight, instead of being bent as in prior sighting devices. The sighting device is preferably injection molded, and has two cross hairs that are also injection molded at the same time as the body member. The light gathering fiber is disposed in the body member at the point of intersection of the cross hairs, and may be press-fit into place. A threaded bolt, which attaches the sighting device to the archery bow, has an end that is overmolded with the body member to form an integral unit. Additional light gathering fibers may be used for different distances, with each of the fibers being substantially parallel to the archer's line of sight. The sighting device may optionally include a source of artificial light for low light conditions, or a lens that is normal to the fiber and that retains the fiber parallel with the archer's line of sight.
