Cavers use one of two harness rigs for ascending from deep pits.

The ropewalker system: The climber is attached to the rope with little one-way cams on each foot that allows him to literally "walk" up the rope.

Or,

The frog system: Here the climber sits back into his body harness that is attached to the rope and then he stands up on both feet while moving the one way "jumar" upwards, much like a hopping frog.

That's all I know about "frogs" and my Granny told me to say all you know about a subject and then shut up.

But before I shut up I would like to say that I miss my Granny.
