The premium Garmin HRM-Dual heart rate strap transmits real-time heart rate data over ANT+® connectivity and BLUETOOTH® Low Energy technology. With it, you will be able to record heart rate data at your Crossbox CBX20 or even the compatible fitness equipment in your favorite class at the gym.

HRM-Dual features a soft strap that is comfortable and adjustable. Simply remove the heart rate module, and it’s washable, too. And don’t worry about running out of juice. The battery lasts for up to 3.5 years.
