Our Take
A premium ANT+ and Bluetooth chest-strap heart rate monitor aimed at serious runners, cyclists, and gym-goers who want broadcast-quality HR data alongside advanced running dynamics. It sits at the top end of the chest-strap market, offering capabilities that go well beyond simple heart rate tracking, and integrates most deeply with Garmin's own ecosystem of watches and head units.
Key Features
Broadcasts simultaneously over ANT+ and Bluetooth Smart, so it can pair with multiple devices at once
Records running dynamics including ground contact time, stride length, vertical oscillation, and vertical ratio
Stores heart rate data internally during pool swimming, syncing to a compatible Garmin watch afterwards
Detects running power natively without requiring a separate foot pod or GPS unit
Compatible with Garmin Connect IQ and third-party apps such as Zwift and TrainerRoad
Soft, fabric electrode strap is machine washable and replaceable independently of the pod
Our Verdict
Worth the investment if you're already in the Garmin ecosystem and want thorough running dynamics or reliable pool-swim HR logging. If you only need accurate heart rate without the extras, or you're using non-Garmin devices, the Polar H10 offers comparable accuracy at a noticeably lower price.
