  • 4iiii Viiiiva Heart Rate Monitor

    The 4iiii Viiiiva Heart Rate Monitor is great for forming a bridge between your other ANT+ products & your iOS or Android smartphone. It uses advanced beat-to-beat measurement to measure your heart rate, any variability and gauge your activity readiness, at the highest levels of accuracy. Used by pros worldwide, the Viiiiva is 10 times more sensitive and 5 times more responsive than most on the market. Your heart rate data can be viewed on head units and other devices in real time, but can also be saved and transferred to another device. The Viiiiva can even collect data from other ANT+ sensors, which can then be transferred via Bluetooth to an iOS or Android smartphone, for fully integrated data recording. The tap-to-pair connection allows you to tap your smart phone to the Viiiiva pod to connect instantly. This monitor is ideal for use alongside Precision and Sportiiii coaching tools, for access to all the data you need to enhance your training. It also has a comfortable, soft & flexible strap so you'll be able to wear this with ease, no matter how long your training session or race is!

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
