Connectivity is where it quietly shines: Bluetooth, ANT+, and 5 kHz all at once, so your watch, phone, and gym equipment can all read the same signal. It's waterproof, holds hours of data internally, and runs on a single button cell. Simple, dependable, and built to disappear under a shirt while you work.

Midway through a grueling interval session, the last thing you want to think about is a sensor slipping or a battery dying. The Garmin HRM-Dual takes the guesswork out of your training data by providing reliable, wireless heart rate tracking that stays out of your way. The soft, adjustable strap feels natural against the skin, preventing that annoying chafing often found with cheaper alternatives.
