With the Rotauf HLT5 avalanche buoy the search and rescue of avalanche victims is faster and easier. The red buoy swims up to the surface, marking the precise location of the victim. The tear-proof Dyneema safety line, which is attached to the victim, helps rescuers to quickly get to the victim. At only 155 grams, the buoy is compactly stored, so that users will barely feel it while free riding or on a ski tour. A firm pull upward on the folded handle is enough to inflate the buoy.
