Medicus Swing Trainers instantly identify flaws in your swing. Our hinged club line is the signature of the our company. Since the early 1990's we have been the leader in creating training products that give you immediate feedback. The hinged club will let you know when you are swinging incorrectly by breaking down at the point where there is a flaw in the swing. Likewise the hinge will stay in alignment with the shaft if the club is swung correctly and you will be able to hit balls with ease. Endorsed by Mark O'Meara, Bruce Fleisher, hank Haney and Jack Lumpkin, the Medicus Swing Trainer has been the #1 training aid ever made.
