Lazer’s LifeBEAM Kit turns your Lazer helmet into a heart rate monitor, no straps needed.

When you install the LifeBEAM accessory into your LifeBEAM-accepting Lazer helmet, turn it on, and put it on your head, it begins transmitting ANT+ and  Bluetooth 4.0 signals. If you’ve got devices that pick up either, you just sync the transmitter to the computer and you’re good to go. No straps to wear, nothing else to think about it.

This is the simplest way to get your heart rate to your computer or smartphone.
