The Zepp Golf 3D Swing Analyzer is a small gadget that attaches to your golf glove and records every aspect of your swing. It records over 1000 data points per second and then allows you to play back your swing from any angle on your smart phone. The app then takes the collected data and provides tips on improving your swing for longer drives and more accuracy. Share your swings with friends or your coach and view and track your improvement over time.
