4iiii Viiiiva HRM ANT+ til BT Bridge Pulsmåler

The Viiiiva heart rate monitor from 4iiii is comfortable, easy to wear and produces very precise measurements. As it allows you to bundle multiple ANT+ signals into one single Bluetooth signal, this heart rate monitor is ideal if you, for example, use an Apple TV in combination with Zwift. The Viiiiva heart rate monitor then acts as an ANT+ bridge, enabling you to connect all your sensors with your Apple TV or other Apple device.

The 4iiii Viiiiva is equipped with the so-called Beat-To-Beat system, a renewed and optimised heart rate measuring system that makes the Viiiiva up to 10 times more sensitive in registering your heartbeat than other heart rate monitors. As such, it ensures highly accurate heart rate data, which is ideal for cyclists who demand a lot of their cycling gear. In addition, the Viiiiva is very user-friendly and has a great memory: it can store up to 65 hours of training data.

Plus, you'll have access to convenient 4iiii training tools like 4iiii PRECISION and Sportiiii coaching with the Viiiiva. These tools help you to easily and clearly keep track of your training data, so you can optimise your training schedule. Do you also work out at the gym? You can also pair the heart rate monitor with cardio exercise machines, ideal if you want to train with heart rate data at the gym. You'll enjoy all the conveniences of the Viiiiva heart rate monitor for up to 200 hours with the included button cell battery.
Want to pair all your ANT+ sensors to a Bluetooth device, like an iPhone? And do you want to have all your data in a central place during a Zwift session? Then choose the 4iiii Viiiiva HRM ANT+ to BT Bridge!

ANT+ to Bluetooth Bridge
This heart rate monitor enables you to easily collect data from other ANT+ bike sensors, like a bike computer, speed sensors and cadence sensors. You can then forward this data to your iOS or Android smartphone or tablet via Bluetooth. This way, you have all your data in one place, which makes the Viiiiva perfect to use in combination with your turbo trainer. You won't need an ANT+ Dongle anymore.
