Tie your line to the ring using a loop knot. The ring will slide smoothly up and down the arrow shaft. Before shooting let the ring slide to the tip of the arrow, nock the arrow, and crank in the slack line. During the draw, the ring and fish line stay out front. Upon release, the stop screw will pick up the ring and line and will not affect the arrow's flight.
Installation is simple.
See picture below. The function of the slide is the same. It again keeps the line out in front of the bow. Then let the slide fall to the tip of the arrow, nock the arrow, and crank up the slack line. The slide will stay in front of the bow when drawn.
