Digital/analog combo device with three antennas. The new Barryvox® S has a large receiving bandwidth and an effective search strip width of 70 meters. It offers users a large, simple interface and intuitive operation. The Smart Search function provides clear instructions thanks to a simple operating concept and quick, precise searching. The Barryvox® S includes the Rescue SEND function to protect non-searching rescuers. In the event of a secondary avalanche, the device automatically switches to SEND in order to locate buried rescuers. The Barryvox® S is also equipped with a Smart Search function, which interacts with the actions of searching rescuers.


  • With a search strip width of 70 meters, the Barryvox® is one of the best devices in the world. Mammut knows that only an avalanche transceiver that is easy to use will save lives in an emergency, so they made fundamental improvements to the user-friendliness of the Barryvox®.
  • The new Barryvox® generation combines a highly powerful search with intuitive handling to help you find buried subjects quickly, easily and reliably.
  • Reverse direction function to avoid 180-degree search errors
  • Group test with clear instructions
  • Smart search interacts with rescuer`s action during the search, making searching simpler and more reliable
  • Buried subjects can be selected from a list, marked (MARK) and unmarked (UNMARK)
