FEATURES of the Mammut Smart Belay Device

  • Popular belay device for both indoor and sport climbers
  • Dynamically brakes the climber in an accidental fall and locks even at low levels of force exerted by the user
  • In the event of sudden shock, the function corresponds to the reflex movements of the human body
  • Improved geometry of the carabiner opening allows comfortable releasing of the lead climber
  • Suitable for all current HMS carabiners and single ropes from 8.7 to 10.5 mm in diameter
  • Ideal for sports, gym, training/workout, and top rope climbing
    *Please note that this is NOT a "hands-off" belay device. The brake-end of the rope must be controlled at all times, and this is merely an "assisted braking device", where the device will function in a way that a portion, not all, of the braking power is done by the device itself. Also, the device is not intended to hold the rope with a 100% positive "stop", as there is some slip built into the device to facilitate a dynamic belay. Sorry to be so mean about it, but this is super serious stuff.

Rated 5 out of 5 by from like a grigri but lighter and simpler I bought this a month ago and love it. It is well designed using some of the same physics as a grigri without all the weight and complexity. You can't use it for repelling, but it's a great complement to a traditional ATC.

Rated 5 out of 5 by from Great Device for Indoor Climbs Great product for top rope climbers. I wanted something that was different than the normal belay device that also would assist in breaking for top rope climbs. It was a tie between this and a grooved atc because what student has a hundred bucks for the gri gri. So this one was the choice and I wasn't disappointed. Lets say you were being careless and just let go of the rope while belaying, the device is made to stop the rope for you (but don't do this obviously). When giving someone a break on a climb, it requires practically no strength to keep them from lowering like the normal device. It is slightly difficult to figure out how to lower someone, but once you get the hang of it you'll never go back. Only downside is that I can see this being obnoxious lead climbing> it doesn't seem to feed rope extremely easy, and it might have a steeper learning curve than other devices. I HAVE seen people use it efficiently though so take a gamble. Overall best device I've used so for and it's and absolute bargain for the price, considering how many useful features there are .

Rated 5 out of 5 by from Very Easy to Use Very easy to use and adds an extra layer of redundancy for belayers.

Rated 3 out of 5 by from Nice sometimes I got this belay device after having used a friends inside for about a month. On tope rope it works well as long as you set up your carabiner appropriately. Otherwise the rope will cross and lock inside of the device and you're stuck. The assisted locking is nice and effective. THe larger size is better for sport, feeds smoother.

Rated 5 out of 5 by from Better than a grigri Use it for top and leading. In my opinion it's better than a grigri or atc. To feed out slack is fast and easy. It locks up automatically when climber falls, and there's no risk of holding the brake down like a grigri

Rated 5 out of 5 by from Great. Locks. Light. Cheap. Compact. Concise. People say it's hard to lead belay with this. It's not. Read the simple 3 step instructions and it works like a charm. I learned to pay out slack fast after literally one practice belay. Get one. That said, it does slip/feed ever so slightly with a thin rope around 9.8 with heavy climber when there's minimal rope drag. Not a problem because they will live and not deck

Rated 2 out of 5 by from NOT FOR THIN ROPE! Works well on thicker rope. It failed to catch my supple 9.5mm Petzl Arial dry rope without a break hand. With normal break hand pressure, it did eventually catch but kept slowly slipping. It took 20-30lbs of break hand pull to stop any slipping. When testing a very stiff 10mm rope, it caught and held very well with or without break hand pressure. This device shows promise, but the soft 9.5mm Petzl Arial with a slippery dry treatment compressed to be much thinner in the device, and failed to gain enough grip. The very stiff 10mm rope compressed much less when going around the friction bars, and held perfectly without a break hand, just like in the demo videos. The device is rated for ropes down to 8.9mm. I wouldn't dare use it on any soft 9.5mm rope or thinner. Test your rope in the device with full body weight before using.

Rated 5 out of 5 by from Work as advertised. The Mammut Smart Belay is a great little belay device. The main thing I want to focus on in the price to performance ratio of this device. I picked mine up from Moosejaw for only 24 bucks on sale. For 24 bucks, the performance is amazing. Some pros and cons:,,,,Pros:,,Cheap,,Auto-locking,,Light,,Easy to use,,,,Cons:,,Not very versatile ,,Giving rope can be tricky,,,,Overall I would say this is a great belay device for a beginner or gym climber. Great for those partners that ask for long takes and fall often. It will always catch a fall even if the belayer is experienced or not paying attention. It lacks a lot of features, but if you want more u should check out the big brother product the Mammut smart alpine. This is by far the cheapest auto locking belay device out there, I highly recommend it.
