Accurate ECG heart rate tracking with up to 400 hours battery life.

And the replaceable battery delivers up to 400 hours – or more than a year of training every day for one hour – of reliable heart rate tracking.
Bluetooth, ANT+, and 5kHz connectivity with 3rd party compatibility.
Connect to your smartphone, broadcast to a huge range of gym equipment, and sync to your favorite fitness and sports apps. Oh, and you can even use it with products from other brands.
Ergonomic, washable soft strap for maximum comfort.
Polar H9 is designed to feel good against your skin for as long, and as often, as you train.
