Heart rate not accurate

[Hannahkayyyy_]

I have head my fit bit versus lite for about a week now and I suspected that the heart rate was not accurate. While in a vigorous workout class my heart rate showed no higher than the 130s although it felt like my heart was beating quite rapidly. Today on the treadmill I felt it should have been much higher. The treadmill itself read 158 while my Fitbit only read about 107-117 steadily. I was more inclined to believe the treadmill due to how I felt. The watch is fairly tight on my wrist so unsure if I’m not wearing properly. Any ideas?

Hello @Hannahkayyyy_, welcome to the Fitbit Community forums. 

Thank you for sharing this information about the trouble you've been having with the accuracy of heart rate information. 

Before considering other options, I would recommend performing a restart on your watch and to follow all the instructions in this article to improve the accuracy of heart rate information: How to I improve the accuracy of my heart rate rate reading?  This has been useful to other users who have experienced something similar. 

Please keep me posted on the outcome.

Thank you for the assistance. I actually learned that the watch was not right enough. Previous directions stated I should be able to put two fingers through the band. However, a friend told me the watch should be snug to your wrist for a more accurate reading.

@Hannahkayyyy_   If the heart rate you're getting from the treadmill is from holding on to a handle or bar on the treadmill, I would NOT trust the treadmill's reading.  They are usually wildly inaccurate.  Use a blood pressure cuff to compare.  They usually give you your heart rate along with your blood pressure.  I periodically compare readings of my heart rate from my Versa Lite with my blood pressure cuff and they are always spot on.  Give or a take a beat or two.
