Pros and cons

According to our heart rate sensor expert
  • Thanks to the Bluetooth connection, you can easily connect the sensor to Bluetooth devices, such as your smartphone, sports watch or bike computer.
  • Because the heart rate sensor is coded, you prevent the signal of your sports buddies from interfering with the signal of your heart rate monitor.
  • You can easily change the batteries of the heart rate sensor yourself.
  • When you forget to disconnect the sensor from the strap, your battery will run out fast.

Accurate heart rate measurement

  • Highly accurate heart rate tracking
  • Comfortable chest strap
  • Hassle free pairing with my Polar M430

Purchased the Polar H9 to complement the wrist-based heart rate tracking by my Polar M430, which I occasionally did not trust. Now a neat, accurate heart rate curve. Clearly better and less susceptible to interference than the pulse registration.

Good thin hr strap

  • Thin

  • Bluetooth and Ant+
  • Small Sharp edge on the strap had to be cut off.

Excellent heart rate belt, I have used an HR belt from a well-known Chinese website for 5 years, this cost 20, - now 28, - I doubted the accuracy and needed to be replaced. So bought this polar h9 the accuracy is the same as the Chinese version. The h9 is a bit thinner and also has ant+. The strap itself is just as good and I have never had any problems with either. I needed one so I'm not sending it back, but there are definitely cheaper options out there!
