@Alpha-156.42 because the producers promote their gears this way?
-
they also say that it doesn’t work the same for everyone
-
@Alpha-156.42 Good point! I think that Suunto should promote the use of a belt, especially with ZoneSense and leave the OHR for walking and 24/7 usage. The belt has a memory function so it can be used for weights, ball sports and other sports where wearing a watch is a problem or cumbersome.

@sartoric on the product pages where they promote the properties of their products?

@Alpha-156.42 Maybe I’m going too technical here, but I don’t think watch manufacturers can ask the general public to make a difference between a direct measurement and an estimator. In the case of HR, only a medical device (e.g. ECG) can actually measure it, OpticalHR is just an estimation based on a “side effect” of the heart pumping blood through veins. If you tell your potential buyers that your watch “estimates” while the others “measure” HR, say goodbye to your sales. The right message to pass is for which scenarios OHR is good enough, and for which don’t (and then you use an HR belt).
Talking HR here, but see that this discussion can be translated to lactate threshold of VO2max… all estimates of a far more complex metric that can only be >measured< in lab conditions with medical equipment. -
@Brad_Olwin I hope Suunto releases a new HR Belt soon, because I’ve been using the old model for 3 years now and I’d love to upgrade to a newone.

@fv4500 "The important thing is to know what is being trusted.
Software provides an interpretation of the data - convenient and useful in everyday life.
Real measurement from medical-grade equipment provides facts under controlled conditions.
There is no need to take sides between software and real measurement.
What matters is understanding the limits of reliability of each.
Use software to track daily trends, and rely on real measurement when scientific-level accuracy is required.

I replace the belt every year, they wear out. The sensors do not wear out as I am still using the sensor from my Ambit 3Peak. I assume you need a new belt not sensor?

While not as precise as a lab test, they are likely good enough for most. My Suunto measures a VO2M from 4 to 8 ml/kg/min low. Not that far off.

@Brad_Olwin impressive indeed!

@Alpha-156.42 100% with you here, important hing is to never loose track of the limitations of the figures at use!

Why do people believe that optical heart rate sensors, no matter if they’re from Garmin, Apple, or other brands, can measure heart rate accurately in every situation?
This is why, text directly from suunto race 2 product page: The redesigned back panel enables better heart rate measurement from the wrist. The result? A seamless, powerful training experience.
But text that it doesn’t work for everyone or every skin tone is buried somewhere in usermanual only.
It is same with sleeptracking or any other metric. If you sell device for 500€ and advertise that it does something, then you must expect that people will require that advertised features just works. This is overal problem of marketing, not just Suunto.
