Comfort and fit are addressed with an upgraded Polar Pro Chest Strap that includes improved electrodes, a simple buckle, and silicone dots to prevent slipping and interference, suitable for a wide range of body sizes (M-XXL).

Connectivity is versatile, supporting Bluetooth, ANT+, and 5 kHz, allowing multiple simultaneous connections, making it compatible with various devices and fitness apps. The monitor is also fully waterproof, suitable for swimming and other water-based activities. Battery life is reliable, with a lithium battery generally providing extended use. The device includes internal memory, allowing for data storage without the immediate need for a connected device, which is useful for long workouts.

It may require some time to get used to its operation and syncing with different devices.

The Garmin HRM-Pro Plus is a premium chest strap heart rate monitor that excels in transmitting accurate heart rate data via ANT+ and BLE technologies. It is particularly well-suited for athletes who train with Garmin devices or compatible fitness equipment. The chest strap captures detailed running dynamics such as vertical oscillation, ground contact time, and stride length, making it very useful for runners looking to improve their form.

Additionally, it stores heart rate data during activities like swimming and syncs it with your Garmin watch afterward, ensuring no data loss even when out of range. The small, lightweight design enhances comfort, and the tool-free battery door adds to its durability and ease of maintenance, with a battery life lasting up to a year. The strap also tracks daily activities like steps and calories, which can be synced with the Garmin Connect app for comprehensive activity monitoring.

However, some users might find wearing a chest strap less comfortable than other heart rate monitoring methods like wristbands. Connectivity is strong with ANT+ and Bluetooth, but it might not be as seamless with non-Garmin devices. The Garmin HRM-Pro Plus is ideal for serious athletes who prioritize accuracy and data richness in their training regimen, though casual users might prefer simpler, more comfortable options.

In terms of battery life, the HRM-Dual stands out with an impressive lifespan of up to 3.5 years, powered by a user-replaceable CR2032 battery. This long battery life means users won't have to worry about frequent replacements, making it a stress-free option for long-term use.

Connectivity is another highlight; the monitor is compatible with smartphones, allowing users to easily sync their data. Garmin is generally known for producing precise heart rate monitors, which implies that this model should perform well in this regard. The device is also designed with water resistance in mind, making it suitable for various activities.

Ease of use seems to be a strong point, given its simple operation and compatibility with various devices. However, users looking for a monitor with an extensive range of advanced features might find it somewhat basic.
