Why is a Polar OH1 optical heart rate sensor recommended?

Polar OH1 is a combo heart rate sensor that connects to Bluetooth® Smart enabled devices, as well as to many Polar products and compatible gym equipment. Therefore the players can also use the OH1 optical heart rate sensors in their own training with a compatible Polar heart rate monitor or gym equipment, and save their training data in the Polar Flow web service.

The Polar Team application also saves data from OH1 heart rate sensors, and the internal memory of OH1 allows you to also record training sessions when not connected to an external recording device. The OH1 optical heart rate sensor also connects to the Polar Beat application. Players can use Beat during their training and save the data in the Polar Flow web service.
