We invite testers from iWorx , Adinstruments, g.tec medical, Biopac, Quinton standard 3-leads Q-tel RMS and other manufacturers of high quality HRM devices to find out which is the most accurate optical sports watch, and to compete with Rob ter Horst in this competition to be the first to know it

• Will optical sports watches ever be as accurate as 3 lead ECG gold standard devices on a treadmill with speeds up to 15 km/h?

• does someone ever proof that Adinstruments LabChart software with the Adinstruments Equivital sensor belt is more accurate than a Polar H10 chest strap?

If someone can publish a scientific paper which shows us that one of these sports watches is highly accurate and can be used for clinical and research applications, we will go back to sports watches to choose those as our research equipment.
