Simply snap the release clip assembly to a rope cleat, transom ring, or dive platform on the transom of your boat. Allows bait 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 cliff, 1st open the release arm, play the fishing line over the arm, then close the arm. Adjust the adjusting screw for the desired attention required for the size of the bait you are trolling.
