Information is Power
By measuring intensity (heart rate) and duration (time) you can avoid over training, help prevent injury, and maximize your chances of achieving your goals.
Heart Rate Transmitter Your Heart Rate Transmitter reads the electrical impulses of your heart and transmits data to your watch. It is one of the most accurate ways to measure heart rate. The Transmitter will function automatically if it is worn correctly within a meter of the watch. The Transmitter is ergonomically designed to fit comfortably during all types of exercise.
ATTENTION: Anyone beginning an exercise regimen for the first time (especially users of pacemakers or other implanted devices) should consult their physician or health professional before using the heart rate monitor.
