Training: High-angle rescue: Two tension system overview

​Here is a quick overview of a Two Tension System with an artificial high directional. Two tension systems can be used on a low directional edge as well (without a high directional) but the belay is kept hand tight with only the main line under tension until the rescuer is over the edge. Once over the edge and in good control, both lines share tension.
