Definitely. The only thing that was really K2 specialized in that video was the skis with pre-drilled tip/tail holes. Here's a newer and way easier to follow video, with the special K2 shovel that has the bolts stashed inside of it.
That video flows way nicer and one thing to note is how he ties the two poles together by interlocking their straps, and tying a saftey rope to one rescuer so that the injured skier on the sled doesnt go shooting downhill.
There's also another company that makes a rescue sled and it's essentially a small blanket that just unrolls and your skis bolt on to it I think. But using the avy shovel, cord, skis, and poles looks way easier and your already carrying those things, so why carry something else?
