  • Effective digital search strip width: 70 meters
  • Digital receiving range: 70 meters
  • Circular receiving field: almost identical receiving range for X and Y antennas
  • Display: display with background lighting, very easy to read even when wearing polarized glasses
  • Acoustic search guidance: a sequence of tones guides you in the direction of the buried subject and ensures that you can keep your eyes on the avalanche field during the search.
  • Reverse direction function to avoid 180-degree search errors
  • Group check: check the transmission frequency and strength of other avalanche transceivers quickly and easily with this function to ensure correct functionality.
  • Intuitive visual interface: guides you intuitively through all search phases and provides an overview of multiple burials.
  • Design: ergonomic, impact-proof and break-proof. Can be operated while wearing gloves
  • Automatic self test: your Barryvox® checks your transmit and search function signal when it is switched on and carries out regular transmission and battery tests.
  • Selection function for multiple burials: in the case of multiple burials, burials can be selected, marked and unmarked on a list.
  • 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)
  • Barryvox carrying system (included in delivery): safe and comfortable wearing of the avalanche transceiver on the upper body.
  • 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)

Powerful search performance can save lives in the backcountry, which is why we insist on serious power from our transceivers. A larger range means that buried transmitters are detected faster, search paths over the avalanche are shorter and rescue times are reduced. With an effective search strip width of 70 meters, the Barryvox® is one of the most powerful transceivers on the market.


Because there’s no time to check the manual when every second counts, Barryvox® devices are specifically designed to be easy to use under extreme stress.
