Intuitive belay device with reliable blocking of the climbing rope. The first generation of the Smart belay device was launched in 2009. Based on this experience, the Smart 2.0 offers a significantly improved braking effect as well as optimized geometry and intuitive handling. The newly developed brake insert blocks the rope in the event of a fall. The belaying method of the Smart 2.0 is analogous to its predecessor and is therefore designed to match the reflex movements of the belayer.
