Genius® Heart Rate Ring

Your heart rate is one of the four vital signs and this ring makes it incredibly easy to monitor. Comfortable, convenient and easy to use, the Genius Heart Rate Ring is completely self-contained so you can just slip it on your finger and press start no wires or chest straps to get in your way. The infrared technology provides accurate and continuous readings, whether you're at work, at play, or at rest.

Producing equivalent results when compared to wrist-type monitors, its features include: Heart Rate Monitor, Clock, Temperature and Training Mode, which records cumulative values; average heart rate, calories burned, training strength, time and min/max target heart rate with alert. It comes with one lithium battery and size-reducing insert. One size fits most.
