Polar / heart-rate-monitor
H10
Chest-strap ECG heart-rate sensor for athletes who prioritise electrical measurement and broad training-device connectivity.
Direct answer
Polar H10 is a chest-strap ECG sensor with Bluetooth and ANT+ support and up to 400 hours of battery use. For HYROX, compare its electrical chest measurement with upper-arm optical sensors on comfort, device compatibility and the training decisions you make from the data.
Verified specifications

Trade-off
Chest placement can feel less convenient during some functional movements than an arm sensor. Comfort, strap fit and device compatibility should decide rather than assuming ECG is always the better wearing experience.
