I picked up a Jarv Run BT - Bluetooth Heart Rate Monitor from amazon over the weekend and tried it out today. It was only slightly noticeable during parts of my 6.4 mile walk today but never uncomfortable. It's not even visible under a loose fitting polyester gym shirt. It synced up to MapMyWalk with no issues and it let me see my heart rate in real time at any time. Very easy to set up and "install" before heading out. I think this is going to track my calories burned during walks, hikes and rides very accurately and very affordably.
