The COROS HR Monitor can also pair with any fitness tracking watch, gym equipment, cycling computers, and more.** **Q: Does the COROS Heart Rate Monitor work over tattoos?** A: Depending on the density of the tattoo, the heart rate monitor may be able to get a reading but it's not guaranteed. If you have tattoos, we recommend adjusting the placement (bicep, forearm, opposite arm). **Q: How do I charge the COROS Heart Rate Monitor?** A: Connect the charging cable to the backside of the heart rate monitor. An orange light will appear while the monitor is charging. The light will turn green once it's fully charged. ## Customer Reviews ### ⭐ Breaks - poor product *by A***R on 28 June 2026* Bought in Jan, broke in Jun. No idea why.
