4iiii – Viiiiva Heart Rate Monitor

I recently picked up a Viiiva – 4iiii heart rate monitor and so far i’m pretty impressed. I need todo some further analysis over the weekend but I really like the ability to use the strap between my iPhone and my Suunto Ambit2 s. Yes, this Heart Rate monitor works both on ANT+ and Bluetooth Low Energy.

More details to follow as I continue to test.
