Winches

They are also a complicated and highly specialised solution to a problem that was solved years ago.
They can only be used to extract a working vehicle going directly forward or backwards.

Your vehicle works, but you need to move someone else.
Your vehicle has drive line damage, but still needs to move.
You need to pull left or right of the centerline to either straighten the vehicle for safety or that is where the anchor point is.
You want to pull a log away from you to clear a track.

If your recovery can't be completed within the length of the equipment, then re-setting the gear is going to be messy or very difficult.

In any of these situations you are better with a Tirfor style job or a powered cable winch, a snatch block or two and some extension straps.

The Land Anchor I can see a use for,they are popular with outback challenge race teams, but I'm not in that much of a hurry.
Rapid anchor; some fencing wire and a bundle of short star pickets and you can make
something that will probably work just as well..
