4-Time Golf Digest Award Winner - Best Full-Swing Training Aid The IMPACT SNAP trains your hands & wrists how to move properly in the golf swing. Practicing with this training aid will teach you a correct, repeatable release, designed after Tiger Woods' 1999 vintage 'stinger'. Learn a motor skill pattern and compress the golf ball like a tour player. Every golf lesson that 4-time teacher of the year, Marty Nowicki, gives to his students starts with impact. If you cannot stabilise the club when you hit the ball, you're never going to have consistency in your golf game. Fix your impact, fix your golf swing and add more distance, more speed & more consistency with the IMPACT SNAP. Used by 22 of the top 100 instructors in the world!
