4iiii Viiiiva Bridge ANT+ chest strap
Viiiiva is an advanced heart rate sensor with many modern technologies.The Viiiiva chest strap is tested and verified by professionals from the QuickStep cycling team and also by passionate amateurs in several sports. Advanced heart rate variability measurement makes Viiiiva ten times more sensitive than most heart rate monitors. This is good for capturing the most sensitive heart rates, measuring heart rate variability and measuring the level of readiness for activity.
Viiiiva's chest strap activity recording means you can not only view data in real time, but you can also save up to 65 hours of training and transfer it to another device or app. The ANT+ sensor allows Viiiiva to collect data from other ANT+ sensors, and then transfer them via Bluetooth Smart to your iOS or Android devices.
Pairing Viiiiva is so easy, just click on your iOS or Android phone and Viiiiva will instantly connect to your device. Viiiiva allows pairing with cardio equipment at the gym for real-time data.
The joint integration of 4iiii products means you can use Viiiiva with coaching tools such as the PRECISION wattmeter and Sportiiii glasses to get a complete picture of your training. A user-friendly application from 4iiii, it allows you to see your activity in real time and transmit activity data to other applications or web services.
