Heart rate not reading during exercise?

[dave_in_ni]

Kind of makes a fitness tracker that cant read heart rate during exercise as much use as a chocolate tea pot? For example

Does this constantly during exercise whether than be running, weights hit, fails to read heart rate for up to 30 seconds at a time, just on and off.  The result of all this being calories and other metrics totally wrong.  30 min HITT yesterday I was rewarded with 77 cals, I don't think so.

This was brand new Versa 2, took it back to shop they gave me another same thing happens.  I have tried it further up my wrist, lower, other wrist.  As you can see no tatoo's, hairy arms, no sweat.  My old Charge 2 does a better job, same HITT workout I would burn 150-170 cals

The Versa 2 heart tracker is garbage.  They sent me a new one several months ago it is even worse.  I just took out the old one and used it today its terrible.  It is useless other than step counting and sleep.  I have been a long time Fitbit user the Blaze was great but the Versa 2 has been a complete waste of money.  I too have tried everything suggested and it simply is not accurate.  Even resting it is not accurate.  I have had nights my HR has gone down into the 30s for random minutes then back up to 60s.  Very disappointed as I love the Fitbit app and all the other things is has but ultimately if they can't fix the HR I am done.

As you can probably tell by the numbers under my name, I am a bit of a cheerleader for the FitBit device/app combination - nearly 1,700 posts and 1,000 votes and 140 best answers (though many, many more thanks for the right answer, just no "best solution", but that is not why I am here). Yes there are individuals with tens of thousands posts, but I am just recently retired and I have only been a FitBit user for a few years.

But the fact remains that they are losing it where it comes to heart rate capture. I started a thread earlier today showing a 28% overstatement of my heart rate while in cool down after a very short exercise period. I have also posted FitBit activity charts from their own web site showing sustained heart rates during treadmill exercises that are literally impossible for me to maintain - BETA blockers will not allow me to maintain a heart rate at between 130 and 150 bpm for over four minutes.

With their third generation optical heart sensor, Apple seems to have lost the issues with heart rate tracking during exercise while FitBit is still lagging behind.

I am currently researching the need to move to the Series 6. I even went ahead and download the OS 7 manual into "Books". If I decide to make the move in the next few days I will still use the iOS app for meal logging and manually create exercise records as needed and I will still participate in the Dashboard and iOS boards here at FitBit.. I have too much invested in the custom foods I have created not to continue unless improvements in the Apple Health app surprises me.

Good luck to you.
