Fit the standard band on your upper arm
Use a soft tape measure where the armband will sit. COROS lists 18–32 cm for the standard band and 24–43 cm for its separate large variant. The button opens the grey standard model. Fit the band snugly against your upper arm without making it uncomfortable.
Check how your watch or app reads heart rate
Look for Bluetooth heart rate sensor support on your watch, bike computer or indoor training app. The armband can pair with up to three compatible Bluetooth receivers. Wear it to wake the sensor, then select it from the receiver’s accessory menu before recording.
How charging and recording work
COROS rates the monitor for up to 38 hours of operation. Recharge it through the supplied magnetic USB cable. It sends readings during training, so keep a compatible device or app connected to capture and save the session.
When to choose a chest strap
If your bike computer receives heart rate through ANT+ only, check a compatible chest strap such as the Polar H10. Choose based on the connections you need and where you prefer to wear the sensor.

Pairing with Garmin
Does the COROS Heart Rate Monitor work with Garmin?
Yes, when your exact Garmin device can receive heart rate from an external Bluetooth sensor. Wear the armband to wake it, then add it from your Garmin device’s sensor menu. A watch that uses Bluetooth to connect to your phone may still require ANT+ for external sensors. Check the manual for your exact Garmin model and the COROS compatibility list before ordering.
