The Magene H803 is the arm heart rate monitor designed to offer maximum comfort and freedom of movement, without compromising the accuracy of heart rate detection. Thanks to next-generation PPG optical technology and the proprietary Magene algorithm, it monitors heart rate in real time with great reliability, even during intense sessions or multi-sport workouts.

It can be worn comfortably on the upper arm or forearm, positioned under the sleeve of your jersey. This solution eliminates the need to wear chest straps under layers of clothing, offering a more natural and comfortable user experience. A benefit particularly appreciated by women, as it does not interfere with sports bras.

The magnetically rechargeable battery provides up to 45 hours of battery life. The device supports dual ANT+ and Bluetooth connectivity, making it compatible with most bike computers, GPS watches, and fitness apps such as Zwift, Strava, OnelapFit, TrainerRoad, Wahoo, and Garmin.

Lightweight, stable, and breathable, the Magene H803 is the ideal companion for those seeking an accurate, practical, and comfortable heart rate monitor, perfect for running, cycling, the gym, and indoor training.
