How to choose
- Compatibility with Garmin Devices. Ensure the heart rate monitor supports ANT+ connectivity, which is the standard for Garmin watches and bike computers. Bluetooth is also useful for pairing with smartphones and gym equipment, but ANT+ is essential for most Garmin features.
- Sensor Type: Chest Strap vs. Optical Armband. Chest straps offer the highest accuracy by measuring electrical signals from the heart, making them ideal for interval training and science-based zones. Optical armbands are more comfortable for long wear and work well for steady-state cardio, but may lag during rapid HR changes.
- Additional Metrics and Features. Some advanced chest straps like the Garmin HRM-Pro Plus provide running dynamics (cadence, ground contact time) which can enhance Garmin's performance analysis. Consider if you need these extras for detailed training feedback.
- Comfort and Fit. Look for adjustable straps with soft materials, especially if you plan long sessions. Removable pods make washing easier and prolong strap life. For sensitive skin, opt for fabric straps over silicone or rubber.
- Battery Life and Power Source. Most heart rate monitors use replaceable coin cell batteries lasting several months to years. Rechargeable models are less common but convenient. Check typical battery life under your usage frequency to avoid mid-workout interruptions.
Frequently asked questions
Does any heart rate monitor work with all Garmin devices?
Most ANT+ compatible chest straps work with all recent Garmin watches and bike computers. However, older Garmin devices may only support ANT+, so verify that your model supports both ANT+ and Bluetooth if you want dual connectivity.
Can I use a Bluetooth-only heart rate monitor with Garmin?
No, Garmin devices primarily use ANT+ for real-time heart rate data. Bluetooth is used for syncing to the Garmin Connect app. For live HR during workouts, you need an ANT+ compatible monitor.
What is the difference between chest strap and optical armband accuracy?
Chest straps measure electrical signals from the heart (ECG), which is more accurate, especially during interval training. Optical armbands use light to detect blood flow, which is generally accurate for steady-state but can lag during rapid HR changes.
How do I connect a heart rate monitor to my Garmin watch?
On your Garmin watch, go to Settings > Sensors & Accessories > Add New. Put the HR monitor in pairing mode (usually by pressing a button). Select it when it appears. For ANT+ devices, the process is similar; ensure the monitor is near the watch.
Can I use a Garmin HR monitor with non-Garmin apps?
Yes, most Garmin HR monitors broadcast Bluetooth as well, allowing connection with apps like Zwift, Peloton, or strava. However, some advanced features may only work with Garmin devices.
Which heart rate monitor is best for swimming with Garmin?
For swimming, the Polar Verity Sense is a top optical armband that stores HR data underwater and syncs to Garmin after the session. The Garmin HRM-Pro Plus is also swim-ready but must be synced later.
The verdict
For unmatched accuracy and running dynamics, the Garmin HRM-Pro Plus is our top pick for Garmin users. If you prioritize value, the CooSpo H6 provides reliable HR tracking at a fraction of the cost. For swimmers, the Polar Verity Sense is the best dedicated option with internal memory for pool sessions.
