How it works

One pull, a red ball, a line

The Avalanche Ball is a buoyancy ball that springs open. It stays on the surface of the avalanche and is connected to your body by a 6 m line.

1 · CAUGHT

The avalanche is not deep

Skier-triggered avalanches break on average only 40 to 50 cm deep. The moving snow is therefore usually too shallow for a full burial. The hard old snow layer below stops you from sinking deeper while it slides.

2 · CARRIED

On the surface until it stops

From being caught until the avalanche stops, the skier stays on the surface. Snow that comes to rest ahead of him in the deposition zone is already so compacted that he does not sink deeper there either.

3 · NOT BURIED

The most common case

If most of the avalanche has already reached the deposition zone ahead of the skier, he usually stays on top or is only partly buried. That is why almost 90% of skiers caught stayed on the surface.

4 · FULLY BURIED

The ball stays visible

If large amounts of snow follow, a full burial can happen. Items that happen to be visible, or an airbag fixed to the body, are then often covered too. Thanks to its 6 m line, the Avalanche Ball moves up and stays visible the longest.

Technology

Spring force instead of gas

Inside, a spring steel frame opens the ball. It needs no gas and no battery. The system has worked reliably for almost 20 years without a single recall.

  • Release as often as you like, with no cost for releasing or checking
  • Ready again at once, simply pack the ball again
  • Can be released as a precaution, for example when turning back after warning signs such as whumpf sounds
  • Several patents, made in Austria
