In 1968, the first Mammut Barryvox transceiver arrived on the market. From that point on, the Barryvox series has seen great success, proving to be some of the most reliable avalanche transceivers available.

Continuing to lead the way in snow safety, the Barryvox S is a highly accurate 3-antenna transceiver. It boasts both digital and analogue modes and comes with a host of Mammut technologies. Intuitive and easy-to-use, the rugged impact-proof device offers top-level performance to maximise chances of success.
