The original and best line of hinged training clubs just got even better. There are two full swing clubs used and endorsed by more than 70 PGA pros. The 5-iron is the club most people are familiar with, but the driver is a must for consistency. Both clubs have a hinge mechanism which breaks down when a flaw occurs in a players swing. This instant feedback will improve timing, tempo, takeaway and swing like never before. The new adjustable hinge lets you vary the tension of the hinge, while the green alignment indicator (on the hinge) provides visual feedback for path. Our patented hinged training club is designed to "break" when a flaw occurs in your swing, giving you positive and constant feedback needed to perfect your game. Golfers of all levels continue to benefit from the unique advantages of the Medicus Pro. The hinged Pro club is the ideal teacher and is so universal because it responds to flaws throughout the swing and can be used virtually anywhere. The Medicus Pro is the best training product on the market! - Davis Love III
