That would be the ideal, and becoming more and more the norm. In the avalanche at Steven's Pass earlier this year that took the lives of 3, everyone had a beacon, but the fourth person had a beacon and an airbag, and the bag saved her.
Rescuers say that Soules was riding alone when the avalanche occurred. He was fully equipped with an avalanche beacon, an Avalung, and an ABS Air Bag System, which had been deployed (although it had been “shredded,” Masters said).

I can tell you this as an avalanche practitioner for over 20 years the hardest thing to predict is the human behavior associated with the decision making that goes into skiing a avalanche prone slope regardless of the level of knowledge or the level of protection one has. The science of avalanches is no mystery and is well documented and published. The science of human decisions is still a mystery (at least to me). You can argue that you may be safer with no equipment because you may be way more conservative on what you decide to ski. What makes someone buy over a grand worth of equipment then go out by themselves? May I suggest you go to avalanche.org and read about all the near misses and fatalities, check out Snowy Torrents and study avalanche accidents. Put yourself in their shoes to understand the decision making. By no means am I judging you or saying you are bad for skiing some pow on a nice day in the Sierras without the basic safety equipment accepted by today’s society. It would be very difficult to explain to a friend’s family why they or you didn’t have the basic equipment if something tragic happened. Start off with a transceiver, shovel and probe. Practice frequently, be conservative with what you ski. Don’t be fooled by thick timber, small slopes or multiple ski tracks. Have a plan, practice one at a time skiing. Give yourself and your friends the best chance should an accident occur.
