The Mammut Smart 2 is a great alternative to a Gri Gri or other mechanical autolocking belay device. It combines the performance of a full autolocker with the low weight and simplicity of a traditional belay plate. In order to avoid moving parts, the Smart 2 uses the belay carabiner as the cam which locks the rope in the event of a fall. When a fall happens, the Smart 2 will dynamically brake the rope, even at low levels of force (e.g. lighter climbers or small top-rope falls).
The geometry has been optimized for ease of paying out the rope and in this newer design it offers significantly improved braking effectiveness thanks to the re-designed brake block inserts. It is ideally paired with any HMS carabiner and works with single ropes from 8.7 to 10.5mm diameter.

Customer Reviews of Mammut Smart 2
I climb mostly indoors with outdoor trips as and when weather allows. I really like this device, it's easy to use and brakes well if needed. Lightweight too. Best when used with a bigger screw gate carabiner rather than a normal size one.
