Mammut Barryvox S Avalanche Transceiver

Mammut Barryvox S Avalanche Transceiver


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.

  • 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
