Magene H303 Heart Rate Monitor

The Magene H303 Heart Rate Monitor uses ECG-based sensing and dedicated algorithms to capture heart rate data during exercise. It is designed to reduce interference from movement and sweat for more stable workout readings.

Dual Wireless Connectivity: ANT+ and Bluetooth support allow the monitor to transmit heart rate data to compatible cycling computers, smartphones and training applications. Both connection types can be used simultaneously for flexible indoor and outdoor training setups.

Long Battery Performance: The H303 offers up to approximately 1000 hours of battery life under laboratory conditions, reducing the need for frequent battery changes. This makes it well suited to regular cycling, running and structured training.

Built for Active Training: An IP67 rating provides protection against dust and water during demanding workouts and changing weather conditions. The chest-strap design keeps the sensor positioned close to the body for consistent heart rate detection.

Magene H303 Heart Rate Monitor combines real-time ECG-based tracking, broad wireless compatibility and long battery life for dependable everyday training.
