The Barryvox S is Mammut's cutting-edge avalanche beacon that's packed with essential features for expediting an efficient search in the event of a burial. The user interface has been redesigned to be simple, intuitive, and glove compatible for no-nonsense operation in an emergency. The backlit display is easily readable, even with polarized glasses. The extra wide 70m search strip is state of the art, and the on-board computer processes signals from multiple buried subjects. The search/send switch locks in the send position, and features a safety backup that automatically switches to send in the event the rescuer stops moving for 4 min. During a search, visual and auditory cues from the device speed direct the rescuer and respond to their actions. The Barryvox S is compatible with lithium-ion batteries for extended operation. Carrying system included.
