Playing golf can be a lot of fun, especially when you know what you are doing. Nobody is born a great golfer, so you need to practice to improve your skills. The SwingTalk can help you improve your technique. It lets you review your swing and putting in 3D on your smartphone. You will be able to track club & shaft trajectory, shaft angle, actual movement of shaft, and other data.
The device gives you voice feedback on your tempo and speed. It fits all kinds of golf clubs (drivers, woods, irons, wedges and putters). The SwingTalk does not weigh a whole lot and pairs with iOS and Android devices. Sets you back under $150 at this time.
