It's a necessity.

I used these in my mountaineering and rock climbing classes, and I must say, it is very simple to use. Whenever going anywhere with a climbing harness, this should be attached to it.

The simplicity of this ATC is what makes it so great. It has two slots, that's all you need. Some of the newer devices coming out have all sorts of the slots and ways to use it. The extra material adds more weight, which isn't needed.

The only concern I have is not about the device, but about how much of a necessity it is. It's great to have, but mistakes do happen, and if you by chance drop it of the edge of a cliff on a multi-pitch climb. A munter hint would be nice to know. So I would recommend always have this ATV or something like it with you, and know have to tie a munter hitch so you can belay/rappel in an emergency.

This is Black Diamond's tube-style belay device.
The Good:
--Utterly simple to setup and use
--Works with any and all ropes on the market (single, double, twin, fat, skinny, etc.)
--Works as a rappel device, too
--Lightweight AND cheap
--No moving parts to service
The Bad:
--No XP grooves, which are handy for skinny ropes holding heavy climbers
--No Guide mode ring; for that you need an ATC-Guide
Every climber should have some sort of tube-style device. There's a reason that such things are almost universally known as "ATCs." It's cheap, it's reliable, and it does more for you than a Grigri. There's no excuse not to have one of these!

Michael Nies at on 12/25/2013

I typically use a Grigri for belay; but, always have an ATC for back-up or if we set up multiple routes and need another belay device. I always use this to clean since it does so well for abseiling.
That said, the BD ATC-XP does the same plus has a friction mode. For only 3 bucks more, I recommend the XP version. If you multi-pitch, get the guide version.
Great product, everyone should have an ATC. 4 stars because at this point, unless you only rap with it, you should just pay a few more bucks and get the ATC-XP

shaun Moyes at on 08/19/2013

This is the best belay/rappel device there is. It is simple, lightweight, and everyone should know how to use it and have one. It doesn't matter if you have a grigri, this does the same job at a tenth of the price. If you are just starting climbing, get one of these to practice in the gym. At my local gym they rent the grigri for free, but this is still my choice.
Just remember that when rappelling it will get hot.

Bernardo Gomez at on 08/31/2013

This belay setup is the way to learn. The ATC is an industry standard and (in my opinion) is the best way for a new climber to learn to belay safely. Eventually if you take to leading and multi pitch you will want to upgrade to an ATC guide or Grigri or equivalent but you will always carry this in your crag bag as a backup.

Danny M H at on 10/13/2013

Your basic ATC. Not the best out there, but it gets the job done, and for the price you can't help but be satisfied with this handy device. I use a Grigri to belay, but I always keep one of these on my harness for short rappels and emergencies. I'd recommend it.

Dahlin Draper at on 05/13/2013

This is a basic atc, it's very simple and gets the job done. Very easy to feed your rope through and most ropes will fit this device. Made with great quality and is very durable. I love the color options! Super good price too!

Joelle Raynes at on 07/31/2013

It's simple, it's timeless, and it's pretty unsafe for most applications besides rap. Grab the Mammut manual belay device or simply invest in a grigri. I don't use it unless I'm abseiling. It shines in that regard. 5 star rappel, 3 star belay.

Thomas Duke at on 04/09/2013
Perfect for everything from the gym to rappelling to outdoor top-roping. May want to invest in something with a high friction or auto-locking mode for more advanced stuff but this thing should still be clipped to your harness as a backup.
BriBerg at on 03/13/2013

Sometimes we just try too hard to make things more complicated then they need to be. Repelling is a breeze. This is the most simple and easy to use. Everyone should have one of these in their bag of tricks.

Negative Reviews:

Twists rope!

Serves its purpose well. Great for indoor climbing. Tends to twist rope after extended use. If you find yourself climbing the same rope time after time it begins to be a problem.

My friends and I have all had this belay device at one time or another and we all say the same thing.

Spend the extra $5 and get the ATC XP

Spend the extra $5 and get the ATC XP. If you get this one you will regret it, and will want to upgrade to the XP. Save your money and hands in the long run and get the XP.

Neutral Reviews:

I'm not a fan because if's you are going outdoors, why wouldn't you want an ATC-XP? I would't like to lead belay with a normal ATC. we use this guys heavily at our work and after only a few year they get really sharp along the edges of the tube (which can tear up your rope). That aside, these guys are overall a good device, simple, and sturdy never had one break on us, absolutely a solid investment. I think the one advantage this one might have over the ATC-XP is for rappelling
