Wahoo Blue HR: using the Bluetooth 4.0 heart rate monitor (7:31) 

This year is shaping up to be a good one for health-related gadgets thanks to the new Bluetooth 4.0 specification and profiles. The $79 Wahoo Blue HR is among the first of these devices to take advantage of this low-powered wireless capability and I took it for a five mile test run. There's no need to charge the heart rate monitor because it runs on a fairly standard watch battery that should last for at least a year.
