Sigma PC9 Heart Rate Monitor

Excl. Tax: £33.29 Incl. Tax: £39.95
Sigma PC9 is a non-coded Pulse Computer / heart rate monitor that has been designed for the health and body conscious sports lover, making it easy to lose weight thanks to its calorie counter and Zone Indicator which shows whether you are exercising within the ideal training zone. The 3 zone audible alarm indicates which zone you are currently exercising in. (Colour reproduction on the website does not always produce an accurate reflection of the true colour. This model is produced in tones of gold/beige/grey.)
The Sigma PC9 Heart Rate Monitor is equipped with a non-coded chest belt from which signals can be received and displayed by most gym equipment (such as treadmills, bikes, rowers, steppers) that have a heart rate receiver built into them. The Sigma PC9 HRM also features an inactive mode (when only the time and date is displayed), using very little power and can therefore be worn as an everyday watch.
