HR comparison

@zhang965
personally, during daytime I find the screen readability to be ok without the backlight on, and when I run at night I always wear a hedlamp… So I prefer to have the backlight disabled and that way the battery can last a little bit longer. -

As discussed long time ago about the feature, it’s ok for walking, but not ok for a pace that you run with.

So I’ve been monitoring my resting HR for the last half an hour, and it’s getting even worse… At the same time I’m checking my HR with my finger on my wrist and the whole time it’s been around 40 bpm.
The S9PP started showing around 70 bpm, then after 10 minutes or so it was down to my correct HR at 40 bpm for like 4 minutes but all of a sudden the reading jumped back to 80-90 bpm, like if it was indeed showing my actual HR doubled. It has remained at 70-90 for the rest of the test.
Also sometimes the readings are like frozen for 10 or 20 seconds, showing the exact same number, and then it jumps to 10 bpm more or less than the previous reading.
-
@dmn23 I’m observing simmilar behaviour during spot reading of HR, the measured values seem to be too high in most cases… the sensor reading starts with quite high value and tries to correct it during further reading, sometimes reaches correct value until watch returns to home screen, sometimes not…in some cases the value seems to be frozen
-
@Dusan-DDD yes I’ve noticed that too, after going to the general screen and getting back to the widget screen, or when I start a sport mode, it’s like the OHR sensor had gone to sleep and it has to turn itself on again, in my case the first readings are always around 70bpm and then they get corrected slowly.
Also, my resting HR readings seem to be more accurate if I check them inside a sport mode, for example starting an activity, than when I just check them with the widget…
-
@dmn23 exactly!
-
@dmn23 @Dusan-DDD This is not my experience with the 9Peak, checked a few times comparing to an Apple Watch on the other wrist. I would contact support, the OHR should be better.
-
@Brad_Olwin Yes, finally I think I will contact customer support before returning the watch as I like everything about it but my awful OHR sensor readings… (and also it would be a pity to return it as I bought it heavily discounted). That was my first idea, that my S9PP OHR sensor might be defective, but after reading so many people having the same issue I thought that it was a widespread problem, not just my watch.
-
@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… -
@dmn23
Suunto official support is good enough, they don’t give you ridiculous advice. -

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