A portable, retractable rope-cocker designed for most TenPoint, Horton, and Wicked Ridge crossbows, including reverse-draw and acute string angle crossbows, the ACUsled reduces a crossbows draw weight by 50 percent and reduces the risk of inaccurate cocking that can occur with traditional rope-cockers, and thus, improves a shooters accuracy. The lightweight units draw cord is pound-for-pound 15 times stronger than steel and completely retracts inside one of the two grips after cocking the crossbow. Then, the grips dovetail neatly together to form a compact unit for easy storage.
