I think armband HR bands should be listed. They are very dependable in comparison to chest straps, more accurate by comparison to wristwatch sensors, and are comfortable. They are available from Polar, Wahoo, and Scosche. All are worn either on the upper forearm or the lower bicep.

The most important difference is that they are suited for extra long wear and are turned on and turned off by you. There’s an on/off switch. Chest straps are generally turned on by activity and they usually pause/go off without activity (as in when you fall into deep sleep).

That’s all. Just wanted to let folks know.
