Wouldn't it be great to have an Optical HRM Pro that could be worn on the wrist or bicep 24/7 with stand-alone activity monitoring (steps, all-day heart rate, calories and intensity minutes) and memory to store training and daily activity data, great for where a watch cannot be worn – data is uploaded to your device when in range. This would be like a Whoop band for when you don't want to sleep with your watch or during the day.
It would also be great for winter activities when you want to wear your watch on the outside of your jacket and not in contact with your skin. I know this would not be as accurate as a chest strap but I hope the new v4 Elevate sensor is getting better and more accurate.
Anyone else want to see this kind of accessory?
