I think that what you're looking for is an avalanche shovel. Google search for lots of choices.
You'd need to dig hard, dig fast with a reliable shovel. Durability is a premium value.
The rest of the local kits that the snowmobilers carry is a Pieps beacon, Avalung and a folding probe set.
Despite that, accidents happen here in the mountains.
There used to be a "devil-may-care" attitude here among the sled-heads.
So many deaths in the last few years has changed the mind-set completely.
Over near Valemount, there are electronic arches that will show a green light if your beacon is functioning properly.
