How to choose
- Compatibility with Garmin Watches. Ensure the arm HR monitor supports ANT+ or Bluetooth Smart to pair with your Garmin watch. Most Garmin models work with both, but older watches may need ANT+ for full features.
- Sensor Type: Optical vs. ECG. Arm monitors use optical sensors that measure blood flow. They are less accurate than chest strap ECG during sudden heart rate changes but are more comfortable for long wear.
- Battery Life and Charging. Consider how often you train. Rechargeable models last 8-40 hours per charge, while coin-cell models can last months but require replacement. Choose based on your usage frequency.
- Comfort and Fit. Look for adjustable straps with breathable materials. A secure fit prevents slippage during sweaty workouts. Try models with different band sizes if you have smaller or larger arms.
- Additional Features (Memory, Running Dynamics). Some monitors store data offline, which is useful if you sometimes train without a watch. Others offer running dynamics like cadence and ground contact time, but require Garmin compatibility.
Frequently asked questions
Can I use any arm heart rate monitor with my Garmin watch?
Most arm heart rate monitors with Bluetooth or ANT+ connectivity can pair with Garmin watches. However, check the product specifications to confirm compatibility with your specific Garmin model, as older watches may have limited Bluetooth support.
Are arm heart rate monitors as accurate as chest straps?
Arm monitors are generally accurate for steady-state activities but may show slight delays or less precision during rapid heart rate changes, such as interval training. Chest straps using ECG are considered the gold standard for accuracy, but many users find arm monitors sufficiently accurate for most workouts.
How should I wear an arm heart rate monitor for best results?
Position the monitor on your upper arm, about 2-3 inches below the armpit, with the sensor flat against the skin. Ensure the band is snug but not too tight. For best optical sensor performance, avoid placing it over tattoos or hairy areas.
Do I need a separate heart rate monitor if I have a Garmin watch with wrist-based HR?
It depends on your needs. Wrist-based HR works well for casual use, but an arm monitor can provide more consistent accuracy during activities with arm movement (like weightlifting) or in cold weather when wrist blood flow may be poor.
How long do arm heart rate monitor batteries last?
Rechargeable models typically last 8 to 40 hours per charge, while coin-cell battery models can last up to a year with regular use. Check the product specs and your training volume to determine which type suits you best.
Can I swim with an arm heart rate monitor?
Some arm HR monitors are waterproof and designed for swimming. Look for models with a rating of IPX7 or higher, or specifically marketed as swim-proof. Note that Bluetooth does not transmit underwater, so you will need one with internal memory to record swim data.
The verdict
The Garmin HRM Pro Plus is the best overall arm heart rate monitor for Garmin users, offering unmatched running dynamics and dual-connectivity reliability. For a budget-friendly alternative, the Polar Verity Sense delivers accurate optical HR with excellent comfort and memory functionality. Runners who prioritize lightweight design will prefer the Wahoo TICKR Fit for its comfortable band and reliable performance in direct sunlight.
