| Our verdict | An inexpensive chest strap that bypasses wrist-based optical lag with electrical pulse sensing. Dual Bluetooth and ANT+ transmission allows connection to cycling computers, gym equipment, or smartwatches. The IP67 rating provides adequate sweat resistance, though long-term strap hygiene requires regular rinsing. | An industry-standard ECG chest strap designed for reliable data during high-intensity training. It bypasses wrist optical latency and pairs with devices across ANT+ and Bluetooth. It requires wearing an elastic chest band and offers no standalone visual interface. |
