Just a few years ago, avalanche airbag use was very rare, especially in the US. But now, we can chose from multiple options such as ABS, Snowpulse/Mammut, Backcountry Access, and WARY/Mystery Ranch, with a multitude more to come in the 2013/2014 winter season. Although the evidence is overwhelmingly compelling that airbag packs work (we have all seen the statistic that 97% of people survive an avalanche when wearing an avalanche airbag pack), but exactly what these statistics mean can be open to interpretation.
