      If Suunto is unable to provide a better WHR accuracy, then Suunto should at least support multiple sensors.

      Personally I can’t wear a chest sensor during longer events. I get skin irritation on the chest to the point of bleeding. I guess that is because of salt accumulating in that area and compression straps of hydration vest moving the chest sensor. I started using Coros armband HR sensor, and it is very good, but it doesn’t support ZoneSense. A good solution would be to use an armband HR sensor for longer events and a chest HR sensor for shorter runs and workouts, but that is impossible without constantly having to re-pair the sensor.

        @Brad_Olwin I have the same bad experience with OHR while running on my newly bought Suunto Race S and I just return to the dealer for checking. It give me the inconsistent heart rate data, sometimes it bump up very high and some times no heart rate signal while I still maintaining the steady speed on the flat road. This morning, while seating at the office, My heart rate should be in normal range 45-50 but it is bump up to 90 - 100 ad I cannot measure the SPo2 on my watch, I tried to measure SPO2 several times and it says it is only 70 which is super ridiculous. I feel sad then go to Suunto Vietnam directly after that, now i need to wait for their check.

          @RdoubleC May I know how is the heart rate on your watch now. I got the same issue as you and now I am waiting the answer from Suunto Vietnam after leaving my watch there one week for checking.

            While reading this I decided to check what my Race S is currently showing as I am taking a coffee break at work. The watch is showing 120-140 while I am sitting still and my pulse is clearly about 50 - I have manually counted it. This is ridiculous!

              @sky-runner My first impression was that the heart rate accuracy was good. After buying the watch, I went on holidays and used the watch mostly for intensive hiking.
              When back home, doing circuit training I noticed the heart rate sensor was displaying half of what I expected it to be. I ordered a new watch strap from Hirsch, model vocem, which better keeps the watch correctly positioned. Accuracy has well increased and I rarely notice heart rate drops

                I was so depressed by the ugliness and cheap feel of my Garmin 265 that I purchased the Suunto race S and wore it in parallel for a month.

                Take-aways:
                General

                • I am stuck in the Garmin eco-system… Would be great to export all activities including gear into Suunto. There are so many things i want to search in my history that Garmin keeps (actually - mostly gear is missing), and MASS import/export

                Pro - Suunto

                • much more asthetic and better built - I love it
                • much nicer overall feel
                • incredibly much better navigation and maps

                Con - Suunto
                1 not as good battery as Garmin - this was a surprise.
                2 alarms are not by weekday (i get up different times different days in predictable pattern, my garmin handles that for wake-up alarms
                3 eco-system issue
                4 the HRM is crap when exercising (However, identical to Garmin when just going about, and very similar HRV for some reason.)

                • I still dont get a VO2max read out after a month of 24/7 wear?? (hence cant judge if it seems correct)

                Overall - impossible choice. I might stick with garmin for ecosystem and some features I am used to. Painful as it is not to have the Suunto on my arm.

                  @Tobias-Petrini hey 😉 you could import all your past activities to suunto using RunGap app on iOS or syncmytrack on android 😉

                  Regarding vo2max I think there is a bug you should run 3 times with an hr belt and then it is unlocked if I remember well 🙈

                        @Josaiplu @Tobias-Petrini It took about 8 months running 3/4 times a week with hr belt for VO2 to show up on my Race(1)…
