The Cycplus H2 is a chest strap heart rate monitor for athletes who want to train with real-time and stable heart rate data. You wear the comfortable sensor on your chest; the adjustable strap keeps it securely in place during cycling, running, and fitness activities. For a reliable measurement, it is recommended to slightly moisten the electrode pads before use. Pairing is wireless via ANT+ and Bluetooth (BLE), allowing the H2 to easily connect with compatible bike computers, sports watches, and training apps. The chest strap automatically activates as soon as you wear it (motion detection) and switches to an energy-saving sleep mode after removal. The battery is replaceable (CR2032) and designed for long-lasting use, so you don't have to constantly recharge.
