      @BrunoH i’ve tried another belt (new one) and the results are the same… but I’ve tried with my wife race s (with the old firmware) and the sensor works flawlessly

        I have same issue with my Race.
        At first it vibrate randomly during activity but I thought it was the SuuntoPlus or Guide or Target. However it start vibrate randomly during daily use.
        After that I did soft reset, everything seems okay. Then I start an activity without SuuntoPlus, or Guide, or any Target, it still vibrate randomly.

        It is very annoying and I thought there is some problem of the watch. Now may be the root cause is the new firmware…

              @jakubdr Same here with Race S. I know I have posted it everywhere, but yep. What you are experiencing is real.

                Here with an update. After couple of days the number of disconnects lowered to 3-5 per hour. The disconnects started always after around 20 minutes into the run. Today I tested Coros Arm Band and no disconnects at all, so at least in my case it seems to be related only to SV and Verity Sense.

                  New firmware 2.44.52, sadly, same “old” problems. The HR band continues to disconnect intermittently 😢

                      I don’t think I’ve ever had a disconnection. Could it be the battery or a worn out belt?
