Comfortable and easy to use, the Nike Triax C5 heart-rate monitor watch lets runners focus on getting into the running groove, not waste time crunching numbers. The Triax C5--which comes with an ergonomic chest strap transmitter--measures your total exercise time and your ECG-accurate average heart rate throughout your workout. As a result, you can better gauge your progress whether you're running sprints, jogging long distances, or working on core fitness.
The watch also tracks your HR with respect to several target HR training zones, making it easy to customize your workout. And thanks to the Triax C5's S-shaped design, the watch curves smoothly around your wrist for a more comfortable fit and easy readability. Other features include time and date displays, an alarm, a scratch-resistant mineral glass crystal, one-touch backlighting, and battery hatches on both the watch and chest strap for easy battery replacement. Water-resistant up to 50 meters, the Nike Triax C5 carries a two-year limited warranty. (Note: The chest transmitter is water-resistant up to 30 meters.)
Product Description
When we were designing this heart rate monitor, we called it "The Basic." Real simple. A few special features that you don't need to use if you don't want to. Continuous heart rate display. One heart rate zone. You select a high and a low heart rate. The watch beeps outside the zone, and at the end of a workout, tells you how long you were able to stay in the zone. Also shows average heart rate at the end of a workout. A simple stopwatch. Tells the time and date. Safe in a swimming pool. The watch and the chest strap both have a battery hatch, so you can change the battery yourself.
