The Constrictor Slide System is a patent pending newly designed bowfishing arrow slide that is created from all stainless steel for unmatched toughness. The Constrictor features a 3 loop tie area that creates opposing forces as it is pulled on. The harder you pull the tighter it holds. The slide functions as a spring becoming its' own shock absorber reducing shock when an arrow is shot. Constrictor has a slim profile that reduces drag, improving accuracy and deep water penetration. Avoid snap back. 5 per package. 5/16″ and 22/64″ models available.
