Belay device recs

I like the mammut smart 2.0. I think it's normally 50 bucks, but REI has it on sale etc. It has no moving parts in it but uses an interior pinching surface that interfaces with the rope and caribiner to assist lock if the rope starts feeding too quickly (someone is falling). With a single mechanism

Belay carabineer

Yeah, silly me for not mentioning my belay device. I use Mammut Smart 2.0, from the manual it says: "To guarantee optimum functioning of the Smart 2.0, the use of a Smart HMS or a similar symmetrical, round-profile HMS carabiner is recommended." What bothers me here is the phrase "symmetrical, round

Belay carabineer

I use a smart alpine, which is a twin-tube version of the Mammut Smart. There is an odd motion that you can do where the curve of the belay biner can bind in the device, locking it up and preventing rope from traveling in either direction in it. I think it is better to have the wider belly, as well

Kinder unter 40kg sichern

Bei uns in der Halle wird in Kinderkursen durchgehend mit GriGri+ gesichert. Scheint zu gehen. Ich nutze für die kleinen ein Mammut Smart 2.0. Geht super, auch mit 20 kg.

Belay Devices

I think one of the, if not the safest, device now is the Mammut smart 2.0 + smarter addon. It is easier to learn than the grigri and therefor way less prone to user error and it is my go-to device when I am teaching new people how to belay.

Gyms Worldwide Increasingly Ban Tube-Style Belay Devices in Favor of ABDs

Look up the Mammut Smart 2.0. It functions like an ATC but has assisted breaking.

which belay device to use?

Mammut Smart 2.0 is really nice for single pitch sport, much easier to feed slack for lead belay compared to a grigri and the assisted breaking bites very hard like a grigri. I know people will say that it’s fine to lead belay with a grigri, but the safe way (without disengaging the cam) is very fin

Using the Ultra as God (aka. Tim Cook) intended

It works great. Replace the Mammut Smart 2.0 with the GriGri+ and you’ll get how I use it. I rappel down the tree with it. Is it the intended use? No but it’s a common practice with those who hunt from a saddle

Looking for gear

Black Diamond sells full kits for rope climbing if you're looking for a bundle. Also, trust me on this, you probably want to get some loose powder chalk and a chalk bag if your area allows it. Still use the liquid chalk, but for the price and how quickly it runs out you'll save money in the long run
