Seiko Epson Corp and Epson Sales Japan Corp announced a sensor device that analyzes golf swings Feb 6, 2014.

The device, "M-Tracer For Golf MT500G," will be released April 10, 2014, in Japan. Though there is no manufacturer's suggested retail price, it will be sold for ¥29,800 (approx US$291, including tax) on the companies' website (Epson Direct Shop). They aim to sell 10,000 units of the product per year.

The size and mass of the MT500G are 50 x 25 x 15.5mm and 15g, respectively. It is attached to the handle of a golf club. Equipped with a lithium (Li) polymer rechargeable battery, it can be continuously used for about four hours when the battery is charged for two hours. A microUSB port is used for charging.

The MT500G comes with two acceleration sensors capable of measuring up to 16G and 300G, respectively, and a gyroscope (3,000°/s) that were developed by Seiko Epson. And it measures the orbit of a swing, frequency of swings, speed of the head, rotation of the shaft, face angle at the time of impact, etc and transmits the data for a smartphone application via Bluetooth.

The smartphone application shows analysis results with movies and in graphs so that it becomes possible to check the user's current swing and compare it with the swings of professional golfers or the user's previous swings. Seiko Epson developed the analysis system of the application with help from the Sports Dynamics and Informatics Laboratory of the Keio Research Institute at SFC.

The numbers of swings that can be recorded by the application and in Seiko Epson's cloud server are 300 and 2,000, respectively. For the future, the company is planning to provide coaching services based on the data stored in the cloud server.
