Here is a smart gadget that helps you improve your golf swings. The SiTa-X comes with a motion sensor to track your swings. Its 9-axis sensor tracks your head speed, swing path, tempo, face angle, distance, and launch angle, so you will have enough data points to identify areas to work on.
You can use this golf trainer anywhere. It can be used by right and left handed users. With SiTa-X, you can simply practice or enter online tournaments to challenge other golfers on a wide variety of fun courses. Expected to ship in April. You can find out more about it here.
