Garmin HRM-Dual Heart Rate Monitor Review

The Garmin HRM-Dual: Final Thoughts from Me

The Garmin HRM-Dual is Garmin’s streamlined approach to heart rate monitoring, ditching the complexities of more advanced sensors for simplicity and reliability. It promises accurate heart rate data via both ANT+ and Bluetooth connectivity, opening doors to training across various platforms and devices. This is more than just a strap; it’s a gateway to understanding your body’s response to physical activity, tailored for athletes of all levels.

I sought out the Garmin HRM-Dual because I was tired of unreliable chest straps that either slipped, failed to connect, or provided inconsistent data. I needed a sensor that would seamlessly integrate with my Garmin watch for outdoor runs and connect to Zwift for indoor cycling sessions without constant fiddling.

My initial impression upon unboxing was positive. The HRM-Dual felt lighter and less bulky than my previous heart rate monitors. The strap material appeared soft and flexible, promising a comfortable fit even during intense workouts.

Compared to the Polar H10, which boasts more advanced features like internal recording, and the Wahoo TICKR X, known for its running dynamics, I chose the Garmin HRM-Dual for its simplicity and compatibility within the Garmin ecosystem. I value the straightforward approach and the dual connectivity options for maximum versatility. My first impression was one of cautious optimism; I was hoping for reliable performance without the frills.

Real-World Testing: Putting Garmin HRM-Dual to the Test

First Use Experience

I first tested the Garmin HRM-Dual during a 10-mile trail run in varied terrain. The conditions were moderately humid, and I wanted to see how well the strap would stay in place and transmit data during high-intensity efforts.

The strap stayed securely in place throughout the entire run, even during steep climbs and descents. I experienced no chafing or discomfort, and the heart rate data on my Garmin watch was consistent with my perceived exertion levels. There were no initial issues or surprises; the HRM-Dual performed exactly as expected.

Extended Use & Reliability

After several months of consistent use, the Garmin HRM-Dual has proven to be a reliable and durable heart rate monitor. I’ve used it for running, cycling (both indoors and outdoors), and even some CrossFit workouts.

There are minimal signs of wear and tear, even after multiple washes. I rinse the strap with water after each use and occasionally wash it with mild soap, which has kept it clean and functioning optimally. It consistently outperforms the cheap generic heart rate straps I’ve used in the past.

Breaking Down the Features of Garmin HRM-Dual

Specifications

The Garmin HRM-Dual boasts ANT+ and Bluetooth Low Energy technology, providing compatibility with a wide range of devices and apps. It weighs a mere 1.9 oz (54.4 g), making it barely noticeable during workouts. The battery life is rated for up to 3.5 years, based on an average use of 1 hour per day, powered by a user-replaceable CR2032 battery. Its water resistance rating is 5 ATM, meaning it’s suitable for swimming, although it doesn’t track swim-specific metrics.

These specifications are critical for a reliable heart rate monitor because they ensure compatibility, comfort, and longevity. The dual connectivity allows me to use it with my Garmin watch, Zwift, and even gym equipment. The long battery life means I don’t have to constantly worry about replacing it, and the water resistance allows for worry-free use during sweaty workouts or swims.

Performance & Functionality

The Garmin HRM-Dual excels at providing accurate and consistent heart rate data. I’ve compared its readings to those from more expensive monitors and found them to be nearly identical, within a negligible margin of error.

Its strength lies in its simplicity and reliability, however it lacks advanced features like running dynamics or internal recording. The HRM-Dual meets and exceeds my expectations for a basic heart rate monitor.

Design & Ergonomics

The Garmin HRM-Dual features a lightweight and comfortable soft strap design. The adjustable strap fits chest sizes from 25″ to 52″ (63.5 cm to 132 cm).

It is user-friendly with no complex setup or calibration required, making it an excellent choice for both beginners and experienced athletes.

Durability & Maintenance

The Garmin HRM-Dual is built to last, as evidenced by its robust construction and minimal wear and tear after months of use.

Maintenance is simple; rinsing the strap after each use and occasional washing is all that’s required. It is easy to maintain and requires no specialized tools or knowledge.

Accessories and Customization Options

The Garmin HRM-Dual doesn’t come with many accessories, focusing on core functionality. The primary “accessory” is the ability to connect to a vast array of Garmin devices, smartphones, and training apps.

There are no real customization options for the HRM-Dual itself, but its compatibility with various devices allows for personalized training experiences. Its compatibility with other brands’ devices is seamless thanks to its ANT+ and Bluetooth connectivity.
