Garmin HRM-Dual™ Heart Rate Monitor

Unlock Peak Performance with Precise Heart Rate Tracking

Imagine pushing your limits during a grueling interval session or a long endurance ride, knowing every beat of your heart is captured with pinpoint accuracy. That's the edge the HRM-Dual heart rate monitor delivers. Unlike wrist-based sensors that can falter with motion or sweat, this chest strap uses proven electrocardiogram (ECG) technology to detect electrical signals directly from your heart. The result? Real-time data that's reliable whether you're sprinting on a trail, crushing a spin class, or dialing in your zones during virtual races.

Athletes swear by chest straps for their consistency, especially in high-intensity scenarios where optical monitors lose steam. Paired with its dual wireless protocols, this monitor seamlessly integrates into your ecosystem, feeding data to smartwatches, bike computers, apps, and gym machines alike.

Seamless Connectivity for Every Workout Environment

Versatility defines the HRM-Dual. It broadcasts heart rate via both ANT+ and Bluetooth Low Energy, opening doors to endless training setups. Connect to your Garmin ecosystem for detailed analytics on the run or bike. Jump into online platforms where you can race friends virtually or follow structured workouts. Even broadcast to spin bikes or ellipticals at the gym—no extra dongles needed.

This dual setup shines in mixed environments. Start your session outdoors with your multisport watch, transition indoors to app-based training, and finish on connected equipment. No interruptions, no pairing hassles—just continuous, actionable insights to refine your training load and recovery.

Engineered for All-Day Comfort and Everyday Durability

Feel the difference of a strap designed with the athlete in mind. The soft, flexible band adjusts effortlessly to fit a wide range of body types, staying secure without chafing during sweaty efforts. An included extender ensures a perfect fit for larger frames, so everyone from elite triathletes to casual joggers benefits.

Maintenance is a breeze: pop out the sensor module, toss the strap in the wash, and you're set for the next session. Rated for 1 ATM water resistance, it handles splashes, rain, and even light pool work without skipping a beat. And with a battery that endures up to 3.5 years at one hour per day, replacements are a distant thought—focus on gains, not gear upkeep.

Maximize Training Zones and Recovery Insights

Heart rate is your body's universal language for effort. With the HRM-Dual, track time in zones to optimize fat burn, build aerobic capacity, or hit anaerobic thresholds. During recovery rides, monitor for overtraining signals like elevated resting rates. Integrate with training platforms to auto-adjust workouts based on your real-time fitness.

For runners, it reveals cadence-heart rate correlations. Cyclists gain power-to-heart efficiency metrics. Cross-trainers appreciate broadcast to multiple devices for team sessions or group classes. Elevate from guesswork to science-backed progress.
