If you train around other people, you know how annoying it can be to have you heart-rate monitor pick up other watches transmissions: Oh crap! 180bpm? The Polar F6 Heart Rate Monitor watch uses coded transmissions so you'll get accurate information from your own body instead of the person running next to you. The OwnZone training program lets you find your optimal exercise zone by running you through a warm-up routine and monitoring your heart rate. From your watch you can select an exercise program based on your goal (aerobic fitness, weight loss, etc) and your F6 will let you know how you're performing compared to your optimal workout while you train. It's pretty simple really. Just do whatever your watch tells you to and you'll be in great shape.Product FeaturesMaterial: PolyurethaneBand Type: T31 coded transmitter Altimeter: No Barometer: No Compass: No Stopwatch: Yes Chronograph: Thermometer: No Heart Rate Monitor: Yes PC Compatible: SonicLink and UpLink Waterproof: Water resistant to 30m Backligh...
