How does a wireless heart rate monitor work?

by on August 29, 2008

My parents want strapless wireless HRM watch's for their birthdays. They want it to beep when entering and exiting their target heart rate zones. They will use this working out, walking, and biking. Would they have to hold their fingers on the sensors of all the watches? Are there watches that have a sensor on your wrist? Dp you preset these? How to they work if they are not getting a constant read out? They don't want chest straps!

I have to order them or find them soon at target or dick's for this weekend.

I'm confused.
Strapless monitors do not continuously monitor, so from my research – I had to get them the ones with the strap.

these devices detect the radial(wrist) pulse, and may be programmed to beep at set numbers. Be proud of your parents for caring about their health, they are setting a good example for you. Check out a place like sharper image for on line orders or check at a local health club or nutrition store.
