The PTK25 Wireless Heart Rate Kit comprises of:
- Polar Receiver Interface Cable (3m)
- Polar Transmitter with Chest Straps
The transmission range between the transmitter and receiver is relatively short (1.2m). As long as you have multiple PowerLabs and each setup is separated by a couple of meters or more, there should be no issues using multiple devices.
You can't however, use more than one system in the same PowerLab as interference will occur.
