Touted to arrive in Japan later this April 10, the M-Tracer will retail for nearly $300 after conversion, where it measures a diminutive 50mm x 25mm x 15.5mm and tips the scales at 15 grams. You will attach the M-Tracer to the handle of a golf club, where a lithium polymer rechargeable battery would keep it going for up to four hours as you practice swing after swing. Juicing it up via a microUSB port takes approximately 2 hours only. How does the M-Tracer work?
Well, a couple of acceleration sensors that can measure up to 16G and 300G, respectively, will be accompanied by a gyroscope (3,000°/s). These work together to measure the orbit of a swing, frequency of swings, speed of the head, rotation of the shaft, face angle at the time of impact, among others, sending such data to be analyzed on your smartphone over Bluetooth.
