The Viiiiva 2.0 heart rate sensor is the perfect partner for your 4iiii power meter, providing a comprehensive picture of your training and competitions. While power measures your external output (watts), heart rate captures your internal physiological response (BPM). This enables a comprehensive understanding of exertion, fitness, and efficiency that power alone cannot provide. Together, they allow you to optimize your training zones and track progress with absolute precision—making the 4iiii Viiiiva and the PRECISION 3+ the ultimate power duo.
Designed for maximum comfort, the Viiiiva boasts an impressive battery life of over 540 hours and IPX7 water resistance, delivering top-tier performance that truly matters to you.
It’s very simple
Thanks to Tap-to-Pair connectivity, you can simply tap your iOS or Android smartphone and your Viiiiva Pod to connect the devices instantly.
Display compatibility gives you the freedom to use your choice of ANT+ and Bluetooth-compatible displays with the Viiiiva.
The 4iiii app lets you view your activity in real time, access upgrades via the web shop, and transfer your activity data to other training apps or websites.
It’s advanced
Activity logging means you can not only view your data in real time, but also store up to 65 hours of data on the Viiiiva and transfer it to another device or application.
With the ANT+ Sensor Bridge, the Viiiiva can collect data from other ANT+ sensors and then transfer it via Bluetooth to your iOS or Android smartphone.
Fitness equipment pairing allows you to pair the Viiiiva with cardio machines at the gym to receive real-time and recorded data.
More than just a heart rate monitor
The Viiiiva isn’t just one of the best heart rate monitors in the world. It also functions as an ANT+ bridge and data logger. This lets you record data from pure ANT+ fitness devices, forward that data to a pure Bluetooth device, or even leave your phone, watch, or head unit at home.
ANT+ bridging with your Viiiiva 2.0
If you have fitness devices that only support ANT+, you can set up your Viiiiva to communicate with them, record their data, and forward it via Bluetooth to your phone, computer, or another pure Bluetooth device. With the 4iiii app, you can connect to and bridge power meters, fitness devices, footpods, and much more.
Data tracking with your Viiiiva 2.0
Your Viiiiva records every second of your workout, including data from paired ANT+ devices. This lets you simply complete your workout without worrying about bringing your headphones or phone, as your Viiiiva securely stores your data for up to 65 hours. Set up this feature using the 4iiii app.
Communication Compatibility
The 4iiii Viiiiva heart rate monitors use both the ANT+ HR and Bluetooth Smart Heart Rate standards, which should make them compatible with almost any head unit, smartphone, or computer you want to connect them to. Check your recording device’s documentation for ANT+ HR or Bluetooth Smart (also known as BLE, BTLE, or BT4.0) heart rate service capability.
