Wrong HR during skitouring
-
Hi, did someone experienced a totally wrong HR on the vertical during an activity lately? I was skitourign and my apple watch was correct signing 146 bpm while my vertcial was always wrong like signing 86 or something… the watch was obviously well positioned. it never happened before
thanks -
@giuliosq, hi, considering that you wrote:

I’m assuming that you’re relying on the optical HR measurement. It’s a common issue that with cold weather (less blood flow) and using poles (sort of sensor cadence locking) the OHR measurement fails, even if the watch is well positioned over the wrist. If you care about HR data, go with HR belt.

@Matúš thanks very much! now I get it, that goes exactly according to my kind of sport actually… HR belt BTW I read that could cause some wrong interactions with the avalanche sensor I have to carry on my chest when doing these kinds of activities

@giuliosq, I know about avalanche transceivers but, since I’m not a skimo guy, I don’t know what’s the interaction between these devices.
There are here some users that practice skimo so, maybe, they will share their experience!

@Matúš But why can the Apple Watch, which also uses photoplethysmography (PPG) heart rate monitoring, provide accurate results, while Suunto’s readings are incorrect? Thank you.

@giuliosq But I also want to ask about my Vertical — why is it that the Apple Watch, which also uses optical heart rate monitoring, can give accurate results? I’ve done tests, and during interval runs and strength training, the Apple Watch is always correct, while the Vertical is consistently wrong.
Thank You. -

I am a mountain and ski touring guide, and maybe can shed some light on this:
Yes, avalanche transceivers could interfere with other wireless devices. It is advised to keep them apart.
The international MountainSafety.info (MSi) board has shared information on proper wearing of avalanche transceivers.
Basically there are two ways: using the supplied harness, or in a zippered pocket.When the harness is used, this has a couple of disadvantages: There must always be a layer of clothing above the transceiver. This is difficult in spring conditions when you just wear a shirt. Plus it is more difficult to reach the device if you need to take it out from under your clothes in emergency.
This is why me and most other mountain guides wear the transceiver in a zip pocket (zip must be closed). This way it is also far enough away from the BLE chest strap.

@MRRUN thanks! my same issue I always think about. Beacause even on the threadmill indoor running the apple watch is always correct on the pace (even without tuning) and the vertical (having it tuned more than once according to the pace of the treadmill) keeps on being wrong. The aplle watch HR in this last ski tour was totally totally perfect., on point And I paid it 1/3 of the vertical… being it BTW a second hand aple watch, from four years ago… the vertical should be way better for the price we pay for it. I have the same issue with the mumber of lengths swam in the pool for example…

@Egika Thanks very much for the clarification. I always tend not to have many stuff blutooth or wifi stuff around the tranceiver

@Egika I Lately BTW started using it in the leg pocket of my bib
