      I might as well just buy a Suunto HR belt if it’s going to spare a lot of grief.

      Today I tried experimenting and something weird happened. I decided to try the H10+ up high on my chest almost under the armpits with the strap across the upper pectorals. I felt on good form (working on high intensity) and quickly noticed the displayed heart rate wasn’t climbing (due to being warmed up my hr is immediately straight up to 188 to 193 ) but my watch was displaying between 80 and 90 and steadily going lower. after 5 minutes I paused to reposition the strap (autopause active) but that messed up even more - the HR value constantly plummeting.

      When I uploaded the data to the phone app it turns out the logged data for the first 5 minutes was logging correct data - around 188 to 193 bpm - and it was only screwed up from after I repositioned the strap.

      I loaded onto Runalyze and the anomalies were bad everywhere so I know that placement of the strap is not helping.

      Is there any explanation however why the first 5 minutes (before the pause) displayed an incorrect HR real time value but logged a correct value? I’m assuming it’s linked somehow to the other HRV issues (ZoneSense was still deactivated).

        @Ian-Beveridge This may be H10-specific, I do not have one so others can comment on that. However, I do have a Garmin HRM-Pro (I am traveling so it is not with me now) that I have worn to test ZS. I have had no issues and the HRM-Pro supports two R-R streams at the same time to two different watches (I did test this) and the ZS on both watches was very similar. I can try to look up the data if you like.

          @Ian-Beveridge I had this happen to me once a few months ago with my Polar H10. Regardless of activity level, the reading was about 60.
          I stopped the activity, deleted the sensor from the watch menu, and paired it again. I’ve never had that problem again.

            @maszop Thanks! I’ll do the same - forget/pair. Perhaps a soft reset of the watch too. I’ll also try the advice to clean the contacts with alcohol. Polar advise not washing the H10+ in a machine - just run tap water over the strap - but I think I’m going to use some soap. Oddly enough today was the first time the H10+ has let me down with basic HR data - but I was definitely experimenting!

            Is it my imagination or are the users of the Suunto sensor experiencing fewer HRV problems than with the H10+? The Suunto sensor is currently at 26% price reduction on Amazon.fr (59€).

              @Brad_Olwin Two R-R streams! You’re scaring me now!
              If you could only have one strap which one would it be - based on your own experience?

                @Ian-Beveridge the two streams simply mean that you can connect the H10 to two different devices. For example your watch and a bike computer.

                For the H10 you have to enable dual BLE connection via the Polar Flow app, if I remember correctly.

                For the time being I’d suggest you follow the numerous advice to maintain your belt to find out whether it’s broken. From personal experience I know that belts wear out over time.

                  @Brad_Olwin you don’t need to go for a HRM Pro for this. I have an HRM Dual that can provide one ANT+ and one Bluetooth stream. I used this for some time to compare my experience of the Race S against the Epix Pro…

                    I run long distances (50k to 100 mile) so the only strap that doesn’t chafe is the Suunto. It is small and I like it quite a bit. I am still using the sensor from when I bought an Ambit3Peak. I replace belts about once a year.

                      @2b2bff When I bought the Pro the Dual was not made or for sale I think.

                        @Brad_Olwin I still have my Polar chest strap and watch from 1993. What surprises me today is the exponential acceleration of tech development. I’m going to work on several proposed fixes for the HRV quality from the H10+ - I’ve already unpaired it and re-paired it - done a soft reset on the watch - cleaned the plastic and metal of the strap with 95% alcohol and adjusted the tightness of the strap around my ribcage (but I can still breathe).

                        If your runs are 50k to 100 miles I assume you are pretty much aerobic all the time. When I remain aerobic on a bike ride or run I’m not getting any of the remaining problems that I’ve been I’ve been getting with the equipment - seems it gets a lot more affected by high intensity work. If working on the strap as described above doesn’t bring results I’ll get a Suunto strap and hope for the best.
