The R3 transmitter enables you to measure your speed, distance and heart rate in a single device.
The SIGMA STS Run wireless technology sends digitally coded data packages to the receiver within the running computer.
All in One
SPEED – DISTANCE – HEART RATE – The R3 transmitter uses an integrated three-axis acceleration sensor to measure acceleration throughout the run and accurately measure speed and distance. The COMFORTEX+ also records an ECG-accurate heart rate measurement.
The running computer combines three functions in one device: speed, distance and heart rate. And there are no extra accessories.
- For HR, speed and distance
