The DualHandle Putting Trainer attaches easily to any putter, and shows golfers the flat wrists necessary to reduce strokes and make putts. Training with separation of the hands is a simple technique that instantly breaks bad putting habits. When using the Medicus Dual Handle the wrists will not break and the triangle formed by the arms and shoulders will be maintained throughout the stroke. Practice putting with the Medicus DualHandle and reduce the amount of strokes you take on the green.
