4iiii has launched the new Viiiiva Heart Rate Monitor — a chest strap device featuring medical grade precision, an IPX7 waterproof rating, instant data transmission via ANT and Bluetooth, and an exceptional battery life of over 540 hours from a single CR2032 coin cell. This innovation packs all of these capabilities under 46 grams and fits chest sizes from 66 to 132 centimetres.
4iiii's Viiiiva Heart Rate Monitor ensures that cyclists and endurance athletes do not have to choose between power data and heart rate data. The device is designed to pair seamlessly with the brand's PRECISION 3+ Powermeter, creating what the company calls the ultimate power couple where external output measured in watts is complemented by internal physiological response measured in beats per minute.
