Despite the fact that it took two full years to go from announced to shipped status, Finis’ Aquapulse is now finally shipping. It’s a head-mounted device that uses an Infrared sensor to monitor your heart rate via your earlobe.

You get the rate in real time through bone conduction technology. Pretty interesting technology, for the health conscious. It will even go underwater for swimmers. It will cost you $149.99. Hey it’s the hardest working muscle in your body. It’s worth it right?
