This means less force on the bodies of the climber and belayer, and on the anchor!__ When lowering, the proprietary Anti-Panic system helps prevent you from losing control of the descent. The brake lever will automatically disengage, causing the cam to automatically reengage if it is opened too quickly or if it is kept too far open where the speed of the descent can become unmanageable. This unique safety feature is particularly useful where there is little friction from rope drag between the belayer and the climber, or during topdown descents.__ The Matik creates a very natural path for the rope that does not require looping or twisting during descent. Combined with the dynamic camming action that limits the impact of the fall, this more natural rope path helps to reduce wear and tear on the rope.__ Other distinguishing features of the Matik include a better method for inserting the rope that eliminates the possibility of clipping a carabiner to the device until it is completely closed.__ NOTE: The assisted braking capability of the Matik does not relieve belayers of the need to adhere to the basic principles of belaying and rappelling. It is imperative to be attentive to the climber's progress and always keep control of the brake line.__WEIGHT: 276 g (9.7 oz)_Rope Diameter Min (mm): 8.6_Rope Diameter Max (mm): Single 10.2_CE: Yes_UIAA: Yes_
