For Mac or PC
You can finally track your movement on the tennis court with the adidas miCoach Speed_Cell. Simply attach the lightweight Speed Cell to your shoe and hit the courts. That's it! Turn your computer into a data-crunching performance analyzer. Easily plugs into your PC or Mac and it captures all measurements of your performance so you can see where you're at and break past those old PBs.
Whether you're playing in a match or just practicing, miCoach will collect your statistics. Share and compare your results with your friends via Facebook or Twitter.
