955 does not lock to heart rate in the beginning of the bike ride

VKK

Now it happened 3 times. My FR955 somehow showed much lower heart rate at the beginning of the bike ride. Each time I took the watch off the wrist, waited until the HR zeroed, put it back and it locked the HR immediately. Is there a cure for it?

    Please stop suggesting chest straps, we are not here for that. Accuracy is not consistency. The watch is less accurate, no doubt, but its accuracy should be enough if it worked.

    I'll second that, looks like how my rides go even through heart rate is 150 BPM the watch shows 70-80

    You can look at the FW version for each activity, maybe it’s worth finding the very first one with oddities and looking at the FW version for it and for the previous, normal one?

    Or, we can be adults and discuss all sides of this issue.   But, please, feel free to continue to speak for all of the forum participants, whether or not your anecdotal opinion actually does.

    No issues prior to 18.22. What I have also found is that a DSW based on heart rate doesn't display this issue as yet.

    Well, OK. I got your point.

    You expect that measuring temperature with hand touching hot surface should be the same consistent while using calibrated PT100 probe.

    I am not so sure.

    I think you know this article about OHR. It explains a lot for me why OHR is only good indicator, but never will be as good as Chest Strap. The same as old school counting beats during 10 seconds and multiplying this by 6 has "built in" error of 6 bpm. Is this good enough consistency for you?

    I can easily imagine while simple factors like how tight your strap is closed on your wrist, can affect measurement. How your sweat ratio changes your blood viscosity. How different grip on bike handlebar change what OHR is looking at.

    Hence, please stop suggesting that investment in chest strap is not the right answer to OHR problems.

    By the way. I have Chest Strap way before I have had any smart / fitness watch. And I was not happy when my next smartphone dropped ANT+ technology despite its OEM was on the list of founders of ANT+ standard. May bad. I have ended with another Chest strap with BT.
