My Blaze shows excessively high heart rates when it is in motion. For comparison I use a Medical Pulse Oximeter (Model: Oxiwatch C20) on the index finger of the same arm. When neither is in motion the two devices show the same heart rate within 1-2 BPM. When in motion the Blaze can show a heart rate as much as 30 BPM higher than the Pulse Oximeter. Can anything be done to make the Blaze heart rate more accurate when the arms are in motion ?

@Dr_LeGrow try changing the possition or tightness of the strap.

Too tight it wont be accurate, too loose it will bounce around to much.

Move it away from the wrist if possible.

Thanks for the suggestions. I have tried both of your suggestions in the past. My watch is not tight and it is not loose. I have moved the watch about 2 inches up my arm and it did help a little but the error still occurs when my arm is moving vs: stationary. One more piece of info: When I'm on a treadmill, if my arms are stationary the heartrate is accurate, but if I move my arms the rate increases at least 20 - 30 BPM. I've had it go to 130 BPM when the machine showed 90 BPM. It seems that the watch is sensitive to both my heart rate and even the slightest movement.
