I wear a Versa 4 and use a heart monitor synced to my NordicTrack. Sometimes they differ as much as 30 bpm. I like to use the SmartAdjust on the NordicTrack to keep my heart rate in the fat burning zone. Can you tell me which device is more reliable?
Best AnswerHi @Callie95 does the Nordictrqck use a chest strap? If so, the Nordictrqck is monitoring the electrical signals that power the heart.
Your Versa is looking at the changes in volume of blood that occur with a heart best.
