Questions & Reviews

Question from Paul Calabro
Probably a dumb question but…
Thoughts on this vs a traditional chest strap, as far as accuracy?

I recently switched to Coros from Garmin, and it’s tempting to try this instead of a chest strap, but I’m skeptical of how accurate an optical HR monitor will be. Seems like bicep is a better location than wrist, but during activity my wrist-only HR reading is accurate maybe… 10% of the time?

Penny for your thoughts.
Answer from Jeremy L
Hi Paul. Not a dumb question, as chest straps have been far more accurate than wrist-based monitors for years. I find the Coros optical HR to have more accuracy than any of my watches. It might be a tad slower than my chest strap, but it's close enough that I have made it my go-to for workouts. For an unbiased take, check out this article.
