Simply snap the Release Clip assembly to a rope cleat, transom ring, or dive platform on the transom of your boat. Allows baits to be trolled below the surface and Keeps lines from being wind blown into other lines causing tangles. To hook your fishing line in the clip, first open the release arm, lay the fishing line over the arm, then close the arm. Adjust the adjusting screw for the desired tension required for the size of bait you are trolling.
