HR comparison

Dusan DDD

@dmn23 Hi, did you went in touch with customer support? If yes, what were their suggestions?
I did short session on eliptical trainer this morning (but without using handles, so more like stair climbing) monitoring HR on the watch and via verity sense on the phone and the results and hr charts were completely different…so would like to know, whether they were able to help you.

@Dusan-DDD yes, they didn’t offer much help, just suggested that a future firmware update could fix the problem… I sent them a photo of where I wear the watch (2 fingers above the wrist), they insisted on wearing the watch almost 4 fingers above the wrist but that didn’t improve the OHR performance. They even said that every other watch model has the same issues regarding OHR, while I know that other watches like the Forerunner 245 have worked for me in the past. They told me that as I had bought the watch on Amazon I could ask for a replacement, but it is sold out on the colour I purchased and Amazon says that they won’t replace the watch in other colours available. So I am returning the watch. To replace it, I have purchased a Forerunner 955, I tested it this morning for a run and the HR readings were flawless, as was the GPS accuracy on dual mode. I still prefer the looks of the S9PP, and the fact that it’s made in Finland, but I won’t keep a watch whose OHR performance is so awful according to my personal experience.

Did they tell you OHR is better in summer?

@zhang965 well they forgot that one, though where I live it’s 15ºC now in winter so maybe that’s why they didn’t even try…

Suunto official support is good enough, they don’t give you ridiculous advice.

Suunto9 Peak PRO wrist HR

Huge difference between wrist and chest strap.

@Felttie tracking HR from a watch when riding is not a good idea. All bike vibrations, and wrist position make it really hard to get good measures

@suzzlo How about running? Wrist is moving even more all the time during running effort, is it more reliable to make comparison testing?

altcmd

@Felttie I am surprised @suzzlo says HR is not reliable when riding and presume he means OHR. Isn’t the hand more stationary than running? I don’t really get this rationale.

Yesterday I forgot my smart belt and was out for a long hiking / Trailrunning day. I had no other choice than OHR on my S9P (non-pro). Wow, it was incredible good! Felt like belt… very good. There must be some improvements in the past via update…

@altcmd rationale is: you grip the handlebars, blood flow is reduced.

altcmd

@isazi Sure, but is there scientific evidence on this?

suzzlo

@Felttie @altcmd I’m talking about OHR. if you fit the watch correctly (tight and 2 fingers above the wrist) usually there is no problem when running, but (at least in my case) the wrist position handling the handlebar and bike vibrations make bad readings.

This is my experience and also others (here in this forum and and also in the Spanish telegram Suunto community)

@suzzlo hmm! Might be more Suunto than in general as I don’t see any difference in OHR reading from the Polar Verity irrespective of whether I wear it on my bicep or forearm. I don’t know if a scientific evidence on this yet and from what people say here, might just be Suunto and how Suunto does it.

@suzzlo There might be some ‘fine-tuning’ needed in the algos as well. I too can confirm that the OHR on the SV while biking (even easy commute without much grip or bouncing gives too low HR, while AW8 is spot on). While running if you ignore the fact that in the beginning of a run it always locks to the cadence (always been the case since Spartan) it usually is much closer to AW or strap (then again I never run without a strap but did a couple of easy runs to test).
