Designed to help teach PureStrike's 5 Simple Keys to Consistency, the Medicus Clear Impact is an indispensable training aid for developing a Weight Forward Swing and a Flat Left Wrist (keys 2 and 3). Clear Impact encourages weight forward distribution and a forward club lean, which allows for better contact while avoiding fat and thin shots. Achieving a Flat Left Wrist compresses the ball at impact for a controlled, pure strike with every swing. You'll see clear impact on your score with this 5SK training aid.
