Ultra long sessions
The rechargeable battery on the Polar OH1 lasts for approximately 12 hours. The battery on the Polar H10 lasts approximately 400 hours. Some easy math reveals that for those ultra long sessions, you should choose Polar H10.
Orthostatic test and R-R recording
You’ll need the Polar H10 for advanced features that require ECG-based heart rate readings, such as the Orthostatic Test available on Polar Vantage V, the Polar V800 GPS sportswatch and the Polar M460 GPS cycling computer.
It’s hard to beat Polar H10 when it comes to extremely accurate heart rate measurements in a fast-paced situation, such as a hard interval training session.

Polar OH1 is easy to slip on your upper or lower arm. Group fitness class about to start? Slip it on. Ready to track that grueling climb on your ride? Slip it on. Cold morning jog? You get the idea.
Both Polar H10 or Polar OH1 work for…
The Polar H10 is ideal for swimming or triathlon, using the 5kHz frequency to transmit your heart rate in the water. Also, you can store one session into the internal memory so you don’t necessarily need to wear a wrist unit at all.
Also the Polar OH1+ product package includes a swimming goggle strap clip that you can wear against your temple to measure your HR accurately while swimming. The Polar OH1 sensor has an internal memory that can store up to 200 hours of training data. Afterwards you can easily sync your data to the Polar Beat app.
connecting to fitness apps
Both Polar sensors use Bluetooth Smart to connect to your phone. Choose a sensor that fits your favorite sport – no clear winner here… except you, of course, if you choose to monitor your heart rate to get the most out of your training session.
