Advanced Sensing Technology

Engineered for Seamless Tracking.

Featuring an integrated multi-channel optical sensor array with 5 LEDs and 4 photodetectors, the monitor captures blood volume fluctuations with clinical accuracy. With built-in wear detection, there are no buttons to fiddle with or accidental battery drains—simply slip the soft fabric band on to power it up, and remove it when you are done.

âš¡ Automatic Wear Detection

Automatically powers on when placed against the skin and sleeps when removed, conserving standby power for weeks.

🔄 Multi-Device Pairing

Broadcast real-time heart rate data to up to 3 Bluetooth-enabled devices simultaneously—including your watch, bike computer, and indoor trainer.

Why It Outperforms Traditional Straps

Comfortable Low-Profile Band

Woven from soft, breathable polyester, nylon, and spandex fibers with a micro-adjustable hook-and-loop closure that sits flat beneath jersey sleeves.

Noise-Free Sensor Placement

Wearing the sensor on the bicep avoids wrist flexion artifacts and movement vibrations caused by rough cycling roads or technical trail downhills.

Universal Brand Compatibility

Pairs seamlessly with all COROS watches as well as Garmin, Wahoo, Apple Watch, Zwift, Rouvy, Hammerhead, and standard Bluetooth training apps.

Magnetic Rapid Charging

Features a snap-on magnetic charging cable that provides a full charge in under 2 hours, eliminating disposable coin-cell battery replacements.

Water-Resistant Durability

Rated to 3 ATM (30 meters) water resistance, making it impervious to torrential trail rainstorms, heavy sweat accumulation, and post-run rinsing.

Removable Washable Strap

Easily detach the sensor pod to hand-wash the elastic band, keeping your gear fresh and odor-free through every South African training block.
