The MIO Alpha Strapless Heart Rate Monitor is a world's first of its kind! It is as accurate as a chest strap without the discomfort. Just put your watch on and that's all you'll need! The two light beams under the watch sense the volume of blood flowing and apply specific algorithms to the pulse signal. Even if you run at high speeds, you will be sure to get the most accurate heart rhythm.
