Camp USA calls its Dyon Mixed Express KS Quickdraw the most sophisticated draw for sport climbers who project at high levels. Its Photo carabiner is a burly biner to keep bolt-dinging to a minimum, and the Dyon carabiner features Camp USA's innovative KeyWire gate that combines the snag-free convenience on a keylock nose with the weight-saving lightness of a wire gate. The Photon carabiner's keylock nose is slimmer to minimize play between the gate and nose. The dogbone varies in width to give an ergonomic grip, and its Karstop Evo retainer stabilizes the Dyon carabiner to ease rope-clipping.
