Whether you're climbing, mountaineering, canyoning, or freeriding, you can abseil the full distance of a rope without having to leave it behind. If one of your ropes become damaged, you have to bail, or you simply want to save as much as weight as possible, take the Beal Escaper, loop it through the anchor, attach it to one end of the rope on a bight, then descend as normal. When you're at the bottom, tug the rope until it's free.
The Beal ESCAPER is a detachable anchor system. It allows you to rappel a full rope length and still release the rope from the anchor.
