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 ### ⭐⭐⭐⭐⭐ Great but you don't get to spit on you hand and rub it like you do a chest strap...... :) *by on Reviewed in the United Kingdom 22 March 2025* Game changer.I've been using chest straps for the last 15 years. Never really any issues other than batteries dying. Gone through Garmins and then maybe 3 wahoo ones. All fine I guess, the Wahoo's only seem to last a couple of years for some reason. Now, pre-setting the strap for these has always been just one of those things I did, either under a tap and embrace the chill when you put it on, or the spit and rub which always had a mildly kinky vibe to it :) Not to mention the more often than not coffee scented strap after a while.Then I finally cave a get this little switcheroo. I wasn't sure how good it would be using the same kind of system that watch based heart rate sensors use (which always seem to lock on to cadence for me). But this thing is solid. Comfy, requires no spit and means i can add a new weird tan line to my arm come summer.But in seriousness, it's accurate, connects to my suunto watch, (i've not used the coros app), is accurate and i honestly forget I'm wearing it. Plus being that it sits on my upper arm and not at the core of my body, it doesn't get anywhere near as sweaty in the heat. ### ⭐⭐⭐⭐⭐ Afterall a coros product *by on Reviewed in India 21 March 2026* I am using it with my coros watch and it's perfect match ### ⭐⭐⭐⭐⭐ Excelente producto *by on Reviewed in Mexico 24 February 2026* Muy buen medidor de frecuencia, siento más confianza que con el reloj.Le dura mucho la pila y es muy cómodo ## Frequently Bought Together - COROS Heart Rate Monitor, Comfort, Easy to wear, Auto-wear Detection, Advanced Sensor, Precise Data, Bluetooth, 38 Hours Battery Life, Connects up to 3 Devices at Once, for Run and Bike - COROS POD 2, Watch Sensor Accessory, Accurate Indoor and Treadmill Distance Measurement, More Sensitive Real-time Pace, Improves GPS Data, Clip onto Shoes or Waistband only Works with COROS Watches - COROS PACE 3 Sport Watch GPS, Lightweight and Comfort, 17 Days Battery Life, Dual-Frequency GPS, Heart Rate, Navigation, Sleep Track, Training Plan, Run, Bike, and Ski (Black Silicone) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/594107851-heart-rate-monitor-grey](https://www.desertcart.co.za/products/594107851-heart-rate-monitor-grey) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-06-03*
