If you are a high performance athlete, you need a high performance heart rate monitor. ALPHA is able to keep up with your high speeds using patented technology from the research labs at Philips Electronics. Two light beams and an electro-optical cell “sense” the volume of blood under your skin. You don’t even have to wear a chest strap for it to work, which means it is ultra comfortable and can be worn all day. It even syncs with many of your favourite smartphone apps.
