How we rated the Garmin HRM

★★★★★4.0/ 5, Vora editorial rating

Our own assessment of a device we do not sell, weighted across six dimensions: accuracy 30 percent, coverage 20 percent, battery 15 percent, value 15 percent, comfort 10 percent, app and ecosystem 10 percent. Every score links to an independent 2024 to 2026 source.

Accuracy90

Peer-reviewed ECG testing puts the Garmin HRM chest strap at MAPE under 4 percent with near-perfect concordance, just behind the Polar H10 reference.

Garmin HRM-Pro chest strap showed MAPE 1.96 to 3.73 percent and CCC 0.95 to 0.99 versus criterion ECG across ruck and cycling; Polar H10 edged it (MAPE 1.28 to 3.40 percent) and the study concludes chest straps should be worn when precise HR is needed.

Coverage & features72

As a sensor it does one job well and adds HR-derived extras, but it does no standalone tracking and the advanced metrics are narrow and Garmin-locked.

Pro Plus transmits Running Dynamics (stride length, vertical ratio, ground contact time), enables Running Power, offloads stored HR for swimming, and sends pace/distance indoors; it has no standalone sleep, steps, or all-day tracking. DC Rainmaker HRM-Pro Plus in-depth review ↗

Battery85

Reviewer-confirmed roughly one year on a user-replaceable CR2032 coin cell, with no charging to manage.

Garmin chest straps run about 1 year on a replaceable CR2032; the HRM-200 adds a tool-less, child-resistant battery door that opens with the strap clasp. DC Rainmaker HRM-200 in-depth review ↗

Comfort58

A chest strap is more noticeable than a ring or watch but reviewers found it comfortable and secure across activities for its form factor.

Called comfortable to wear for a range of exercises and reported that it wrapped around the torso securely and did not budge during testing. Trusted Reviews HRM-200 ↗

App & ecosystem74

Dual ANT+ and Bluetooth make it work with any app for basic HR, but the advanced value of the hero Pro Plus is locked to Garmin watches.

Dual ANT+ and BLE transmission works with any app, but the reviewer states the Pro Plus basically makes no sense for anyone who does not own a Garmin watch. DC Rainmaker HRM-Pro Plus in-depth review ↗

Value80

No subscription and a multi-year lifespan on cheap replaceable batteries, though the Pro Plus premium only pays off inside Garmin.

HRM-200 is 79.99 USD with no subscription and about a year per battery; the Pro Plus at about 129 USD adds running dynamics and cached HR for Garmin owners. DC Rainmaker HRM-200 in-depth review ↗
