Mammut Barryvox S Avalanche Transceiver

Digital/analog combo avalanche transceiver with three antennas. The new Mammut 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.


Asking yourself if you should get the Mammut Barryvox or the Mammut Barryvox S?  Here are some of the key differences:

Both Barryvox transceivers sit as the most user-friendly, most efficient search tools available, but the Mammut Barryvox S is a cut above. However, just because it’s got more features doesn’t mean it’s harder to use or for more advanced users!  Here are the top benefits you’ll see from opting for the Barryvox S over the Barryvox:

  • Larger Screen (2.2” vs. 2″) – easier to see & read, even with the lighting is bad.
  • Dynamic Screen Icons – the icons move as the searcher does, indicating exactly what the searcher should be doing (i.e. Is the icon running? The searcher should be doing a quick coarse search. Is it crawling?  Time for a pinpoint search).
  • Smart Search – though the user never sees this feature, it operates in the background and makes searching more efficient than ever – even if the searcher is less than perfect.
  • Auto Guidance – no more signal overlap from other transceivers. No more “stop stand still.” Just a one-track path to the buried victim.
  • Lithium Batteries – the Barryvox S can utilize Lithium batteries or alkaline batteries. Lithium batteries last longer, are lighter and don’t damage with acid corrosion.

Effective digital search strip width: 70 meters

Digital receiving bandwidth: 70 meters

Extended search range: extended receiving bandwidth (analog): up to 95 m; Extended search strip width (analog): 80 m

Circular receiving field: almost identical receiving bandwidth 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, followed by 1 hour SEARCH)

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, frequency check 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
