3BaysGSA PUTT is a patent pending innovation in golf putting technology. It captures the club head swing motion of your putter and sends the information instantly to your smart phone (iPhone, iPad, iPod) through its unique GSA PUTT app, which compares each club head motion from different angles simultaneously. It compares and analyzes each putt against your best or your LPGA / PGA instructor's best putt for greater accuracy.
