This head unit is a bargain! It's accurate, can track a ton of information, has GPS navigation and a full color screen. It connects thru Blutooth Smart and ANT+so it will work with just about all power meters on the market. If you have a dual leg power meter you can track each leg's power and stroke separately. It can even connect via wifi for uploads to most training platforms and has a feature that will allow you to control your smart trainer and ride virtual routes!
