My Charge 3 was not showing accurate heart rate readings.

I finally broke down and got a polar h10 chest strap.  It is inconvenient to use but it is accurate.  I checked it several times against a blood pressure cuff.  While doing arobic exercise the Polar H10 shows an average HB of 116.  Min of 101 and Max of 123.  The same session on the Fitbit Charge 3 shows an average HB of 133.  Min of 102 and a Max of 173.

Finally got the wrist position down to get accurate results from Charge 3 during aerobic exercise.  When worn a finger length above wrist bone was getting horribly high and inaccurate results.  Moved it up my wrist about four fingers.  It now fairly closely match a Polar H10 chest strap.

I'm glad to hear that your Fitbit Charge 3 is providing you more accurate heart rate readings. For tips to improve the accuracy of a heart-rate reading, please visit this article.

Please be aware that your Fitbit Tracker uses PurePulse technology to record your heart rate, if you compare it with a different technology, you might get different results.

I merged your posts in this thread since they are about the same topic.
