      @JaakkoK Wait for the next update hopefully soon. On field test firmware I am not having any drop outs. I did not with your production firmware but did have other issues with the Suunto Smart Sensor. You have done everything necessary and the strap is not that old.
      I do find in cold weather if I am not sweating enough and wearing a tech shirt get HR interference from static.

            @salusi I have the same issue, my current solution is to use an old Polar H10 I have lying around.

            There are other threads where people seem to have the same issue.

              Has this issue been fixed? I recently got a vertical (latest firmware) with a sensor belt and my belt keeps loosing connection with the watch.

                  It also happens with the Suunto Run. And it’s not exclusive to the Chest Strap. Using Bluetooth phones to listen to music also makes this issue appear. The issue almost always appears after around 1h training, pauses or GPS disconnections during tunnel passages.

                    This evening it happened with my race s and polar oh1+

                    Heartrate band disconnected, didn’t reconnect and the buildin heartrate sensor didn’t take over.

                    My stryd stayed connected though.

                    I will report to suunto support.

                      It isn’t supposed to be taking over.

                        @2b2bff but it seems it does. At least on the Suunto Run. I saved today’s run to report tomorrow.

                        2 issues happened. Max heart rate much higher than registered on the HR chart and in the end I did a pause and the connection to the Suunto Chest Straps was lost when I restarted a few seconds later.

                        The maximum HR registered by the chest strap was 154bpm but somehow on the Max HR in the intervals summary many values of 170bpm (these are wrong) appears. Also it can be seen that the HR chart doesn’t end. It was the pause. Unfortunately Suunto seems unable to solve this issue that affects all watches and makes all data contaminated by wrong measures or lack of them.
