hrm-swim

Record and store your heart rate data while swimming with the HRM-Swim from Garmin. The HRM-Swim is specifically designed for swimmers and can be used both in pools and open water. It stores up to 20 hours of heart rate data and interval summaries. Once you're out of the water, all your recorded data is automatically sent to your separately available Garmin device-for example, the Forerunner 920XT. To ensure its effectiveness and longevity, the HRM-Swim is designed to be resistant to harmful pool chemicals and is engineered with a non-slip strap so it stays in place during complex physical maneuvers, such as turns and wall push-offs.
