Black Diamond ATC Pilot or Gri Gri for a beginner?
Most of the comments thus far aren’t aware of the differences between a standard ATC, and an ATC Pilot. You can’t go wrong with a grigri or Pilot but the Pilot is the better option for most first devices IMO. Unless you’re gifting it to someone. My recommendation is not as a former Black Diamond rep

Belay Devices
There is no right answer because you are looking for an assisted belay device for the wrong reasons. The extra layer of assistance is a huge and non-negligible help for a person who can belay but is momentarily caught off-guard (not paying attention), incapacitated, or the situation escalates (eg a

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

Advice after top-rope belaying/lowering accident?
This happened to me before - lowering a heavier climber and I got my hand stuck in the ATC and it was so painful. I got an auto braking device (Mammut Smart) which feels a lot like an ATC but has the auto brake similar to a grigri. I personally don't like a grigri because it is harder on lead belay.

What is the best belay device for a left-handed 13 year old?
Left handed belay instructor here… Like it or not, the industry is moving towards assisted breaking devices, so don’t buy an ATC. On toprope, you can actually apply some pretty slick left handed technique with a GriGri, but not so much when lead belaying. Any of the geometry assisted devices (BD Pil

Backing up the reverso for kids
The mammut smart and atc Pilot are geometry based and use almost the same technique for belaying as your reverso, with the benefit of the backup that you’re trying to figure out. I’m not a fan of making something that is not complex more complex because I don’t want to pick a tool that already exist

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.

Weekly Question Thread (aka Friday New Climber Thread). ALL QUESTIONS GO HERE
You don't need a stainless steel carabiner to belay. Mammut sells a locker that matches the Smart, just buy that one.

New Belay Device for Top Roping
As someone who has a gri gri and doesn't use it much, I still think that if you're asking something as broad as "What belay device should I get?" And your input is essentially, "Yeah, idk man, just want something besides my ATC!" The answer is pretty much always gonna be a gri gri because in reality
