For all here, be advised that a new development in archery equipment is about to be available to the archery public.The Turbo Nock!! Designed for the archer shooting a compound bow, release and fall away arrow rest this promises to be one of the greatest innovations to archery since the development of the compound bow.No more fletching on the arrow shaft. These small profile nocks have their own built in airfoil on the nock body that spins and stabilizes better than fletching ever could.Even 2613`s can be tamed to eliminate that annoying porpoising flight that can rob you of X`s or points and will stabilze even the largest broadheads for perfect flight!!! They will be generally available in a couple of months as soon as manufacturing proceeds and can keep up with demand.No hype, just fact.The archery world is about to get knocked on its collective ear!!!!!!! 3D shooters are going to love these babies as well as target archers and bow hunters who use the above equipment.I will be shooting them at the Vegas Shoot for any one who will be there.I am a professional archer and these things REALLY WORK!!!!!!!!
