The H9 for live readings, the H10 for more flexibility
If one device already records every workout, the H9 has the connections you need. If you want a watch and phone app to receive the same live heart rate over Bluetooth, the H10 can keep two Bluetooth connections when enabled.
Measure for the included band
Measure your chest where the band will sit. The H9 listing is for the XS–S Soft Strap. Check its own sizing before ordering. Polar specifies a chest circumference of 71–118 cm for the H10’s black M–XXL Pro Strap.
Pair with the receiver you train with
Wear the strap and open the receiver’s external sensor settings to add heart rate. If you use both a bike computer and a training app, decide which device should use ANT+ or Bluetooth and test the connection before a workout.
