Mammut's innovative Pulse Barryvox Avalanche Beacon, provides the ability to perform pre-search triage & find multiple buried victims quickly. The Pulse uses a 360 degree direction arrow that leading to the shortest path to the victim & eliminating the need for a final grid search. The Pulse Beacon can search for up to eight signals at once. A triple antenna eliminates all signals except the one you're following & marks victims once they're located. This beacon even shows which signals are being searched for by other Pulse users, so the search is more efficient. If you're the one buried, this Mammut beacon also has a motion sensor that detects vital signs & lets other Pulse users know you're still alive. In avalanche rescue, efficiency is everything; this Mammut beacon shortens your search & buys time for whoever is buried.
