2-to-1 mechanical advantage is most often used to help a person out of a pothole or past a similar obstacle.
Attach one end of the rope to an anchor.
Hold onto the other end.
Lower the middle part of the rope to the person in the pothole.
The person in the pothole runs the rope through a carabiner on their harness (short easy hauls) or through a Micro Traxion on their harness (long hard hauls).
The person in the pothole grabs onto the strand of rope attached to the anchor and pulls up while the person at the top also pulls their strand.
The mechanical advantage makes the haul fast and easy.
