Technology for Golf: the 3Bays Golf Swing Analyzer. This clever little golf swing analyzer slots into the top of your club, you won’t even know it is there. Link it to your phone and its app, and you will have access to diagnostics such as Top of Backswing, Release Point, Power Zone, and Shaft Lean. You can also calculate your tempo, Face Angle, Club Head Speed, and Attainable Ball Distance. The app can actually record your swing and compare that to your previous results. So much in such a little device. See more about Technology in Sports.
