I have trained using HIIT for years but since purchasing Versa 3 January 2024 my H/R is a lot less than it shoul be. I’ve now gone back to using my polar F2.

Hi there, @1WG. Welcome to the Fitbit Community Forums. I'm sorry to hear that your Versa 3 is not tracking your heart rate accurately. I understand where your concern is coming from. I will do my best to help you with this!
Several factors can affect heart rate, including air temperature, stress level, alcohol or caffeine intake, immune response to illness, and medication use (source).
Exercising in cold weather can make it more difficult for your device to track your heart rate, as environmental conditions can affect skin perfusion (the amount of blood that flows through your skin). Spikes in your heart rate during sleep may be caused by sudden movements (for example, waking up and getting out of bed), or a weak signal due to wrist placement.
As with all heart-rate tracking technology, accuracy is affected by personal physiology, device location on your arm, and type of movement. For a more accurate heart-rate reading:
To resolve common issues, see our troubleshooting steps in What factors can affect my heart-rate reading on my Fitbit device?
