Additionally, the flexible strand creates a loop configured to extend beyond the end of the arrow shaft when the sliding portion contacts the stop.

Abstract: An arrowhead for bowfishing supports pivoting barbs that may refracted rearward to pass through a fish and then extended to retain the fish on the arrow. The barbs provide a truncated stop surface striking a rear of the arrow tip when the arrow tip is tightened on the arrowhead to prevent their forward motion from the extended position when the tip is tightened on the arrowhead and yet to allow such motion when the tip is slightly loosened but not removed. The barbs are offset with respect to their pivot point so that a slight loosening of the arrow tip also allows the barbs to pass forward over the arrow tip for retraction of the fish from the arrow while the tip is retained on the arrowhead.

Abstract: A reel seat (5) for affixing a fishing reel (80) to an archery bow (1) using a threaded fastener (16) attached to a support shaft (9). The foot (6) of the fishing reel (80) rests upon the shaft (9) and is secured between a cap (7) and a rear bushing (8). The rear bushing (8) is stationary while the cap (7) is movable along the shaft (9). Screwing a threaded fastener (23) into the shaft (9) advances the removable cap (7) towards the stationary rear bushing (8) and decreases the separation of the rear bushing (8) and the cap (7). The decreased distance results in physical forces and friction being applied to the reel foot, supporting member, and said structures. Prior to fully tightening the fastener (23), the fishing reel (80) may be placed in an infinite number of circumferential positions (90, 91, 92) with respect to the longitudinal axis (86) of the shaft (9).
