Mobiplex, a Silicon Valley tech company, recently released a device called SwingTIP, which is a light-weight, Bluetooth-enabled clip that attaches to your golf club. It analyzes your swing and provides real time feedback. Inside the clip there is a wireless 3-D motion sensor that’s paired with an app. When you swing, the device analyzes 900 samples of data — including speed, swing tempo and the overall path of the clubhead — and produces a 3-D animation video for you to watch and critique afterwards. The app is available for free download on both iOS or Android.
