Heart rate too high Versa

[Linfra]

 I have used the Charge 2 for 2 years. My all time max HR has been 183, sounds ok sins I just turned 44 years old. I just got a Versa. I have used it two times during work outs. The first time I got 192, and today I got 203. Why is it a differens between the two watches? Which are correct?

I have just got the versa and when the hr monitor is working properly it seems quite accurate. unfortunately I seem to a software bug every so often where the heart goes all over the place while I'm resting. Doing restarts seem to eventually sort it but there is no logic to how many I have to do. Has anyone else had this issue and is there a fix  

Thanks MP

@Linfra You may need more measurements. Just in case toggle your heart rate monitor on your Versa ON/OFF (go to Settings on your Versa, scroll down to heart rate and toggle with a reboot of the tracker in-between). You can reboot your Versa by pressing and holding the left and bottom right buttons until Fitbit logo flashes. If possible, please attach some screenshots of your heart rate recordings (from Fitbit mobile app) for the workouts as well as all day recordings.

@Pegomas1 merged your post with this one.

I have rebooted the Versa. I will use it tomorrow for a spinning clas. I can tell you how it worked out.

The first picture was wrong. This is all day.

@Linfra Thank you for posting the screenshots. If you take a closer look at the first one (the all-day recording), your heart rate does not exceed 180. Only in workout, mode there's a short spike, probably lasting less than a minute, and that's why after calculation on fitbit servers, it doesn't get to your all-day recording. it's an outlier. this is nothing unusual as the versa measures your HR more often during workouts and adjusts.

@Linfra what i'm saying is I do not see anything in your HR chart that you mentioned, i.e. the value that you referred to (over 200), which means it must have been a spike. As both trackers have slightly different sensors, the algorithms probably differ as well. At the end of the day, what matters is what you get on your Dashboard and not during a spike.
