A compact, lightweight, self contained rappel apparatus by which a person such as a parachuting smoke jumper, aviator, or other person may safety descend a line or rope from a tree canopy or other high perch to the ground or a lower elevation. The invention is designed for one-handed use with a preferred figure 8 system of descent line reeving around and about the top pipe and bottom pipe of the descender that results in multiple frictional line-to-line contact points as the line crosses itself in each figure 8 wrap in the area between the top pipe and bottom pipe.
