Edelrid’s new Giga Jul looks deceptively like your standard two-tube device. But by moving the slider in the center and flipping the orientation, you quickly go from a manual-braking to assisted-braking device—the options include manual-braking or assisted-braking lead and toprope belay, guide-mode top belay, and manual-braking or assisted-braking rappel. Basically, the Giga Jul is many different devices in one featherweight (4.2-ounce) package.
