Heart rate monitors - wrist watch type
Hello! First time here!
I did a search but couldn't quite find what I was looking for. I just started on a treadmill this week and would like to keep my pulse in a target range while exercising. I am seeing a lot of these that look like a watch and you put two fingers on the metal contacts for a reading. They are ranging from $50 to $100.
Does anyone know if they are accurate? Like plus or minus how many beats per minute? I wouldn't mind forking out the cash if they are fairly accurate. They sure would be convenient.
Thanks so much.
