I think all need to know that oHR is very personal in terms of performance. I have seen @Dimitrios-Kanellopoulos in person with great oHR and me not so good. There are improvements coming but this is not an easy thing to do. Mine works great for walking and gym exercises like stretching. Running flats or uphill works well but not downhill. I also have the few minutes of way too high HR. This is helped if you select the sport start screen so HR is engaged but do not start. I did this while driving to my last run and did not get the high HR at the start.
But remember that different individuals will have different experiences.

This is a nice reading about this topic

@Brad_Olwin Interesting life hack. Will try tomorrow… What about GPS and foot pod?

@Brad_Olwin Interesting life hack. Will try tomorrow… What about GPS and foot pod?
I live/work at 5500 feet ~1600m in the Southwest (Boulder, CO) where there are few significant impediments to GPS so I rarely have GPS issues. I start my runs as soon as GPS locks on (usually a few seconds). Footpod, when I use one is Stryd and it is uncalibrated so the pace/distance/cadence all come from Stryd and not GPS. I typically use this only for intervals or when doing long races (Endurance mode) and I want better pace information.

Today, for the first time, I had this problem.
I started walking (fast but not so fast
) and after a while I noticed HR going up with no reason. Once touched the gauge max I stopped and paused the activity (checking if I was dying by heart attack 
) put some air between the watch and the arm, then resumed … and started running, with HR back to normal.I don’t know if it has some relation with this or not, but once I paused the activity I’ve heard strange noises (like connection issue) in my BT earphones

I think the problem comes from GPS antenna, because when I start a indoor running, the problem does not happen

Any solution for this?
I always have an extreme peak at the beginning -

I always have an extreme peak at the beginningMy watch is working great. Everything I do just try to wear more tightly than usual and wait few minutes before hit start button

@vietpq same for me… Constantly have a spike to 200bpm on spartan trainer for first 10 minutes, even if I run 6min/km. After that settles down. Annoying, I think it’s fixable by firmware, but hard to know. On the upside, it makes me warm up more, like others here.

My WHR is just rubbish. During cycling or running, it stays for very long near my resting HR, then after maybe 15-20 minutes it shoots up but it’s far from anything accurate. During simple walking, it has sudden spikes. Comparing to the chest strap is not just a bit off, it’s totally wrong. It happened a few times I forgot my chest strap and had to rely on WRH ( SSWHR Baro ) and HR reading was just useless. I used to moan a lot about Fitbit Ionic device thinking that it cannot get any worse. I replaced it to SSWHR Baro to find out that indeed, it can

@Adam-Bialogonski Did you try this : https://forum.suunto.com/topic/2120/suunto-9-ohr-readings
It improved a lot the OHR reading for me (that and wearing the watch 2-3cms from my wrist)
-
@jean-william-cousin yes I did. One of the first thing I tried. I also made sure the watch is kept stable in that position using a sweatband before it so it would prevent sliding it down the wrist. Still nothing improved.
-
@Adam-Bialogonski the solution is to warm up for 2 km, end run, then start a new run. (until, and big if, suunto fixes this…)
-
related and I would love to hear if that helped

@Adam-Bialogonski you should try to wear more tightly, it will help
