For swimmers with Versa, do you find the calories burnt during swimming exercise reasonable? Since it doesn’t track heart rate, I think he calories burnt during one hour free style swimming is very inaccurate!
Best AnswerNo doubt the calories are off. Optical heart rate sensors and water don't mix. I just swim with it and view it more as an estimate. I'm really just trying to track distance. The only way to get an accurate reading while swimming is to use a chest strap; the technology is just limited.
