The Edelrid Eddy is the perfect belaying device for both sport and indoor climbing by experts and novices alike. The revolutionary Eddy is simple to use. Key features include: Ability to use from 9mm to 11mm ropes, logical threading of the rope and a built-in emergency breaking system that eliminates the "panic pull" that could lead to serious injury with other autolocking belay devices. The Eddy’s breaking cam is completely internal eliminating dangers of your belayer accidentally holding the cam in the open position. These features and its simplicity convinced Climbing Magazine to name it Editors’ Choice. CE Certified.
