The Mammut Barryvox S avalanche beacon increases your search strip width to 70 meters. You understand that only a transceiver that may be easy to make use of will save lives in an emergency, so appreciate the fundamental improvements to the user-friendliness of the Barryvox on this new, 2017 upgrade. Its powerful search and intuitive handling assist you to find buried subjects quickly, easily and reliably. It has a big, simple interface and intuitive operation. Also, the Smart Search function will provide you with clear instructions thanks to a simple operating concept and quick, precise searching. Includes the Rescue Send function to give protection to non-searching rescuers. In the event of a secondary avalanche, the device routinely switches to Send so as to locate buried rescuers.
