Building on the success of the original Swingbyte -- a portable device that clips to the shaft of any club and sends swing specs to smartphones or tablets -- Swingbyte 2 is designed to make working on your swing even easier. The new version weighs less than an ounce and aligns the centers of gravity of the sensor and the club, making for more stability and more accurate feedback. Along with a more advanced iPad app -- with improved ability to record and compare swings -- the Swingbyte 2 comes with a new alignment aid to help create more precise, dependable swing data. Among the data it records: clubhead speed, swing plane, face angle, loft and lie angles, and a 3-D visual swing-path representation.
At $149, the Swingbyte 2 sensor comes with an account at my.swingbyte.com, along with the free Swingbyte app.
