Garmin HRM-Pro Plus
Question about Garmin HRM-Pro Plus
Does the belt work just as well when worn on the upper arm only? Or is that not possible at all?
Helpful answer
The Garmin HRM-Pro Plus is specially designed to be worn around the chest. Wearing the strap on the upper arm can lead to inaccurate measurements as the strap may not be positioned correctly on the chest. To ensure the best accuracy, Garmin recommends wearing the strap around the chest, just below the pectoral muscles.
