Polar H10 Heart Rate Sensor Chest Strap - Black, M-XXL, ECG Accurate, ANT+ & Bluetooth, Waterproof 30m

The Polar H10 is a chest heart rate monitor renowned for its unmatched ECG accuracy, making it the gold standard for athletes who demand precise data. Its soft textile strap with silicone grip dots ensures a secure, comfortable fit during even the most intense workouts, while dual Bluetooth and ANT+ connectivity offers seamless integration with sports watches, fitness apps, and gym equipment. With a user-replaceable CR2025 battery lasting up to 400 hours and 30m water resistance, the H10 is built to perform in any environment, from pool laps to mountain trails.

Advantages

The Polar H10 delivers the most accurate heart rate measurement in the Polar lineup, thanks to its advanced ECG technology. The strap's silicone dots and soft fabric keep the sensor firmly in place, eliminating signal dropouts during high-motion activities. It supports simultaneous dual Bluetooth connections, allowing you to connect to two devices at once—like a watch and a phone—while also broadcasting to ANT+ devices. The built-in memory stores one training session, so you can leave your phone behind and sync later. With a battery life of up to 400 hours and a simple coin-cell replacement, you'll spend less time maintaining and more time training.
