The Polar A370 is a continuous heart rate monitoring watch. This item is BLACK, other colored bands are available.
Comfortable band material allows for continuous activity level monitoring. The A370 features patented LED technology for sensing your heart rate by reflecting certain wavelengths of light off of the blood flowing through your skin. Our test crew reports that A370 takes about 2 hours to charge and will run for more than 18 hours of continuous heart rate monitoring.
This device is preferred for use with our base stations because it indicates when it is connected to the base station.
