4iiii - Viiiiva HEART RATE MONITOR

The Viiiiva is so much more than a heart rate monitor. The Viiiiva can act as an ANT+ to Bluetooth bridge so you can broadcast your ANT+ devices to your Bluetooth devices all through your Viiiiva heart rate monitor. The Viiiiva also records every second of your workout, including data from paired ANT+ devices. If something happens to your head unit or watch the Viiiiva will keep your data safe, up to 65 hours of it.


4iiii Viiiiva heart rate monitors use both the ANT+ PWR and Bluetooth Smart Cycling Power Service standards, which makes them compatible with nearly every headunit, smartphone, or computer you wish to connect to. Check your recording device documentation for ANT+ PWR or Bluetooth Smart (also called BLE, BTLE, or BT4.0) Cycling Power Service capability.

Tip: A 4iiii Viiiiva can be used to record your workouts along with your heart rate.
