Magene H303 Heart Rate Monitor

Clinical-grade heart rate accuracy in a comfortable chest strap. The Magene H303 connects via Bluetooth and ANT+ simultaneously to deliver real-time cardiac data to your sports watch, cycling computer, or fitness app  so you always train in the right zone.

Heart rate zone training is one of the most evidence-based approaches to improving cardiovascular fitness and managing recovery. The prerequisite is accurate, reliable data  something wrist-based optical sensors still struggle to deliver during high-intensity activity. The H303 uses a chest electrode to measure the electrical signal of your heart directly  providing clinical-grade accuracy that optical sensors cannot match. Dual Bluetooth and ANT+ connectivity ensures it pairs with virtually any sports device or app on the market
