Well, it's not really so much of a product a person can buy, but a technique learned under proper instruction that is used by search & rescue teams. I learned, practised, was tested on it (passed) and used it when I was a volunteer at my local Humane Society, for recovery of injured horses in ravines when there were no anchor points in the nearby vicinity. The gear used at the Humane Society is not special, however, it is large & heavy duty, and it's the same set-up now used my our county search & rescue teams, as taught to them by my leader-instructor (I helped at a couple of those training sessions).
And, in certain circumstances I've been able to use a modified (smaller & lighter) version to recover my vehicle when I was alone.
I'll see if I can put some descriptive words and drawings together with the details, cautionary notes, and disclaimers. I would stress that a person practice the set-up technique in a situation where the vehicle is not stranded... several times to get comfortable and knowledgable. Use at your own risk as I'm not a certified instructor. Maybe if I can get to one of the WTW rallys someday I can do a demo.
