This is not actually a new aiming system I have been using this aiming method for over 30 years. Once you learn the system, it becomes automatic and you don't even think about it. A gentleman by the name of " BOB DEEM " sold this system for about $ 25.00 back then, and it has to do with using your ferrule. I give Pool Lessons and I teach my students this method, but only after their game gets to a certain level. I don't want to confuse the student to depend 100% on this aiming system, because there are always exceptions to the rule.
