Mammut Barryvox S2 Beacon - Unisex

Whether navigating a familiar skin track or dropping into fresh terrain deep in the backcountry, the Barryvox S2 gives you fast, clear direction if things go sideways. A 70m range, intelligent fine search, and advanced multiple-burial tools keep you focused and in control under pressure. The interface walks you through each search phase without guesswork, while pro-level features support fast decisions in complex rescues. For ski tourers and mountain professionals who take their safety systems seriously, this transceiver works hard so you can move faster and think more clearly in the moments that matter most.
