Extremely reliable with advanced features for novices or pros; 70m strip search width

The Mammut Barryvox S has a large receiving bandwidth and an effective search strip width of 70 meters. Digital/analog combo device with three antennas. 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.
This generation of Barryvox beacons continues the faultless reliability that the previous avalanche transceivers were known for. At the same time, Mammut has incorporated some major enhancements in terms of usability and performance. This beacon combines a highly powerful search with intuitive handling to help you find buried subjects quickly, easily and reliably.
