Runtastic Combo Fitness chest belt with heart rate measurement

The intelligent Runtastic Bluetooth Smart Combo ribbon allows you to transfer heart rate data directly to your smartphone or Runtastic mobile application without having to use another adapter or device. The Bluetooth Smart wireless technology is used for transmission. Combined with the ability to record speed, pace, altitude, distance and time, you can easily create your own training that can not only be analyzed, but can also be made more effective by successive steps. This chest strap also allows you to monitor the duration of activity, burned calories, set interval training and track data on a daily, weekly and monthly basis and much more. It also works at a frequency of 5.3 kHz (ANT +) , which allows it to communicate with the cardio device. A great advantage is an integrated music player.
