About this item

  • The lightweight 80 grams Smart 2.0 is easy to operate and has no moving parts or levers.
  • As it operates according to the tube principle, the Smart 2.0 is therefore suitable for both lead climbing and top rope climbing.
  • In the event of a fall, the Smart 2.0 blocks the climbing rope, with the newly developed high-performance brake insert interacting with the belay carabiner. It therefore offers the belayer optimal support and significantly improved safety.
  • Mammut recommends use of the Smart HMS for the Smart 2.0. It is suitable for rope diameters from 8.7 to 10.5 mm.
  • Weight [g]: 80

Product Description

Intuitive belay device with reliable blocking of the climbing rope. The first generation of the Smart belay device was successfully launched in 2009. 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.

I've had to use a grigri a few times and I do not like having moving parts in a belay device. This thing feels great to belay with (top rope or sport). Much more comfortable than other devices I've used before. Would recommend!

Easy to use and quick to take or feed rope. Extra safety over an ATC is great too. Glad it comes in orange now to match the rest of my hardware.

4.0 out of 5 stars Top Rope Belaying Beast/Lead Climbing Clumsy
Reviewed in the United States on September 16, 2023
Size: One SizeColor: BlackVerified Purchase
Def a learning curve just like any auto locking belay device compared to atc just on descending climbers and giving out slack for leading climbers. I’ve only climbed indoors so far and love this device for top rope because it makes things much smoother with the thicker ropes my gym has. When setting the belay device for top rope I simply filter the end of the rope into the mammut and carabiner attached to my harness quick n simple and tie off a safety knot.
I just got into lead climbing and I’m a bit fidgety when giving out slack as I don’t like to keep the device open for long with my thumb so it can be stressful at times when I’m short roping my friends when they’re clipping due to the auto lock coming down on me when trying to be quick with it. With lead belay setup you have to detach the entire device then attach the device with the rope inserted back to ur carabiner. When bringing down climbers on lead you need to find the sweet spot on the way you angle the device with ur thumb and control the pace of the descent with ur break hand. (Ive lost control here and there nothin catastrophic but one close call when trying out a new carabiner that was thinner then my OG one)
I’d recommend it but I’m still exploring my options. I prefer the smoothness of my black diamond atc over mammut on lead belay but it does not have the added safety that I want. I plan on putting it up against the edelrid giga jul soon since some prefer it over the grigri

I use it as a rappelling device for saddle hunting and it works great. It’s a much more affordable option not the mad rock safeguard and it’s in stock.

It is a little picky on the carabiner you use but once find the right one, it’s solid.

The Mammut Smart has long been my favorite belay device, with the only drawback being the jerky lowering action. 2.0 has solved that problem!

This is pre-use, so not a definitive review. It was time to consider a 1-rope device, and this is closer to my old ATC than a Gri-gri would be. Looks well-made/designed and easy to adapt to, but some climbing is needed to be sure.
