Mammut Barryvox S Avalanche Beacon



  • TypeDigital/analog combo device with 3 antennas
  • Effective digital search strip width: 70 meters
  • Digital receiving range: 70 meters
  • Extended search range: extended receiving bandwidth (analog): up to 95 m; Extended search strip width (analog): 100 m
  • Circular receiving field: almost identical receiving range for X and Y antennas
  • Lithium-enabled: also works with lithium batteries: Less risk of leakage. More stable in low temperatures. Longer battery life (350 hours SEND)
  • Display: display with background lighting, very easy to read even when wearing polarized glasses
  • Acoustic search guidance: allows the rescuer to visually search the avalanche field
  • Reverse direction function to avoid 180-degree search errors
  • Group test with clear instructions
  • Visual interface: shows distance, direction and number of buried subjects
  • Design: ergonomic, impact-proof and break-proof. Can be operated while wearing gloves
  • Device tests: automatic self-test and function test
  • Smart search interacts with rescuer`s action during the search, making searching simpler and more reliable
  • Multiple buried subjects: digital signal processing in the event of several buried subjects
  • Buried subjects can be selected from a list, marked (MARK) and unmarked (UNMARK)
  • Automatic switching from send to search (Auto Revert): if a rescuer does not move for 4 minutes, we assume a secondary avalanche and the device switches to SEND mode (motion-sensor controlled)
  • Rescue SEND: Protective function for non-searching rescuers. In the event of a secondary avalanche it automatically switches to SEND to allow the rescuer to be located
  • Auto guidance: device continues to guide the rescuer to the buried subject in the event of signal failures or overlaps
  • Vital data: 3D sensor helps the rescuer concentrate his or her resources on the buried subjects with the highest chance of survival
  • Advanced search settings: individually configurable search settings: pro search, acoustic and visual guidance; automatic switching from search to send (Auto Revert)
  • Alternative search mode (analog mode) helps in resolving demanding search scenarios
  • Personalization: start screen and user texts (for example, owner information) can be personalized
  • Attachment: includes highly functional Barryvox carrying system
  • W-Link: Additional communication channel for improved search performance
  • Manage the device fleet via W-Link
  • Updatable software
  • Operating temperature: -25° to +45° Celsius (-13° to +113° Fahrenheit)

Product Type Avalanche Safety

With a search strip width of 70 meters, the Barryvox S Avalanche Beacon from Mammut is one of the best devices in the world for safety on the slopes. Only an avalanche transceiver that is easy to use will save lives in an emergency, so it has been designed with user-friendliness in mind.

With one of the largest receiving bandwidths and one of the widest safely usable search strips on the market; where it really stands out is its intuitive operation. The new generation continues the faultless reliability that the previous avalanche transceivers were known for. At the same time, there are some major enhancements in terms of usability and performance - a highly powerful search with intuitive handling to help you find buried subjects quickly, easily and reliably.

Digital/analog combo device with three antennas. 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. It is also equipped with a Smart Search function, which interacts with the actions of searching rescuers.
