Meet the ClubHub: a sensor kit that lets you keep an eye on your golf game and figure out how to improve it. These sensors let you see real-time data for every shot, track shot distances and locations on the course, view 3D images of your swing, and share swing and round data with others.
ClubHub sensors and the companion app provide you with swing speed, face angle, angle of attack, tempo, transition angle, and other useful information on your smartphone. To get started, simply attach the sensors to your clubs, and you are set. Like what you see? You may want to support his project on Kickstarter.
