Barryvox S

Product DescriptionBarryvox S Transceiver

A design so intuitive, you’ll nearly be able to operate it with your eyes closed. Mammut’s redesign of the Barryvox (a leading industry beacon for almost 10 years) focused on instinctive use in a highly stressful emergency. New antennas and processors allow for a 70m wide search strip. Quick and accurate arrow direction quickly gets you where you need to be. A better screen, marking and unmarking capabilities, analog mode and advanced search settings make this pro model ideal for ski guides, ski patrollers and heavy users with a deep understanding of various search methods. This impressive beacon makes snow safety simpler, more efficient and unconditionally reliable when it really counts.
