When the bowfishing line is tied directly to the tail of an arrow, it can knot with the bowstrings as you draw back. The knot will cause the arrow to stop short in mid-flight and suddenly “snap-back” toward the shooter. AMS Safety Slides were designed to keep the bowfishing line out in front of the bow at all times. Simply nock your arrow with the Safety Slide out in front of your rest. Tighten the line on your Retriever between it and the slide and push the line into the Line Retainer found on the side of your reel.
