Polar H10 vs. Verity Sense: chest strap or armband?
The Polar H10 measures heart rate from a chest strap. The Polar Verity Sense uses an optical armband sensor and includes a clip for your swim goggles. Where you wear it, how you start a recording, and how you power it all depend on the sensor you choose.

Recording capacity and battery life measure different things. Check the stated battery life for each sensor’s power source.
Chest strap or optical armband
Polar H10 for chest strap wear
The H10 measures heart rate with electrodes in the strap. Check the size and fit before training. If you plan to view your heart rate on a watch or app, confirm it accepts a Bluetooth or ANT+ heart rate sensor. The H10 also offers 5 kHz GymLink for compatible receivers.
Polar Verity Sense for armband wear
The Verity Sense uses light to read your pulse and fits into an armband. Polar shows positions on your forearm or upper arm. To use its swim mode, check how to attach the clip to your goggle strap and place the sensor at your temple.
What to check for your usual workouts
Decide whether you want live heart rate or a workout you can review later. For live data, check that your receiver supports the sensor. If you prefer to carry fewer devices, check how the recording mode starts and when you need to sync.
Recording and battery life
The H10 uses a replaceable battery. To record on the sensor, start a session in Polar Beat and retrieve it when you return. It stores one workout at a time.
The rechargeable Verity Sense has heart rate, recording, and swimming modes. In recording mode, you can start from the sensor. Polar’s technical specs list storage for up to 600 hours of training data and up to 30 hours of continuous training per charge under the stated conditions.
If you switch between short and long workouts, check your remaining charge and when you last transferred a recording. Each sensor has a different routine for charging or changing the battery.
