New Sony Gadget Fixes Your Swing

If you ever wanted to dissect your tennis game down to the last ball spin, Sony’s Smart Tennis Sensor is here to help. Launching in Australia on Thursday, the small sensor — which connects to the end of the handle of specially-built rackets from tennis brands Wilson, HEAD, Prince and YONEX — feeds data via Bluetooth directly to Sony's Smart Tennis Sensor Android and iOS smartphone app. The sensor is fairly lightweight at 8 grams, so will not seriously weigh down your serve.
