Is the Polar H10 more accurate than a watch's wrist heart rate?

Yes. Chest straps read the heart's electrical signal directly, so they hold up better than wrist optical sensors during intervals, cold weather and weight training.

Can the H10 connect to two devices at once?

Yes. It has two Bluetooth channels, so you can pair a watch and a phone app together, plus ANT+ for gym equipment.

Can I swim with the Polar H10?

The sensor is rated 3 ATM, so it handles pool swimming and showers. The strap itself does not store data, so you need a compatible watch or device recording nearby.

What battery does it use, and can I replace it?

It uses a CR2025 coin cell. You open the pod with a coin and swap the battery yourself.

Which strap size should I pick?

Polar lists M-XXL for 67-95 cm chests and XS-S for 58-71 cm. Measure your chest at the band line and pick the range you fall in.

Does it work with Garmin and Apple watches?

It pairs over Bluetooth with most Garmin, Polar, Suunto and Apple watches and with phones running apps like Strava or Polar Beat.

Our take on the Polar H10 Heart Rate Sensor

The Polar H10 is a chest-strap heart rate sensor that streams over Bluetooth and ANT+ to watches, phones and gym equipment. It is Polar's top strap, with dual-channel Bluetooth so two devices can connect at once, and it is rated 3 ATM for swimming and showering. Owners and reviewers rate its readings above wrist-based optical sensors, especially in intervals and cold weather, but the strap needs regular washing and a moistened contact patch to read cleanly. It suits runners, cyclists and gym users who want reliable heart-rate data on whatever device they already own.
