Pup Actually,,,, I do have twin Pro 40 black and pewter target bows, well one is my wife's[8D] The pull cord attaches to the top limb at the base of the fork. When you draw the bow, the limb comes back and down allowing the return spring to raise the launcher and arrow into position. With my 29 1/2 inch draw, I'm getting about 7 1/2 inches of support duration before launcher drop starts on this bow. On my Patriot Dually, I get about 10 1/2 inches[] Good luck with yours!!!!
