The TomTom Bandit Action Camera uses Bluetooth®® Smart to connect to sensors. Bluetooth® Smart is a version of Bluetooth® which is designed for connecting small, simple sensors to smartphones and computers.
We have tested TomTom Bandit with the TomTom Heart Rate Monitor. However, you should be able to use any Bluetooth® Smart heart rate monitor with TomTom Bandit.
Note: The TomTom Heart Rate monitor does not work underwater.
