Mammut Smart 2.0

"The Smart 2.0 from Mammut is an innovative belay device that has been specially developed for indoor climbing and scrambling. Weighing just 80 grams, it is lightweight and easy to use as it has no moving parts or levers. The device works according to the tried-and-tested Tuber principle and is suitable for both lead climbing and top rope climbing."
"An outstanding feature of the Smart 2.0 is the newly developed high-performancebrakeinsert, which blocks the climbing rope in the event of a fall. This system interacts optimally with the belay carabiner and offers the belayer more support and safety. The improved braking effect and optimized geometry of the device ensure intuitive handling that corresponds to the belayer's reflex movements."
"Mammut recommends the matching Smart HMS carabiner for use with the Smart 2.0. The Smart 2.0 is suitable for rope diameters from 8.7 to 10.5 mm, which makes it versatile and ensures additional safety when climbing. Based on the experience gained with the first generation of the Smart belay device, the Smart 2.0 offers significantly improved performance and is an indispensable tool for all climbing enthusiasts"
