Smart 2.0 is an intuitive belay device from Mammut with reliable blocking of the climbing rope. Built on the experience the new Smart 2.0 offers significantly improved braking effectiveness as well as optimized geometry and intuitive handling. The newly developed brake insert blocks the rope in the event of a fall. The belaying action of the Smart 2.0 is the same as the previous model and is therefore tailored to the belayer's reflex movements.\n\n\n\nMammut recommends use of the Smart HMS for the Smart 2.0. It is suitable for rope diameters from 8.7 to 10.5 mm. Mammut Smart 2.0 Black | Buy Mammut Smart 2.0 Black here | Outnorth
