    Will the real ATC please stand up?

    They say imitation is the most sincere form of flattery, which is why you won't find the Black Diamond ATC griping about the wannabes. Built to handle ropes ranging in diameter from 7.7mm to 11mm, this simple but functional device handles belaying and rappelling with kink-free ease. And weighing in at a slim 60-grams, it's a must-have addition to your harness.

    • Smooth-handling symmetric geometry

    My First

    • Familiarity: I've used it several times

    I just started building out my climbing gear and as a beginner I love this thing. So easy to use, straight forward, and a classic. This is the model that was recommended to me in my climbing course I took in Oregon through the Chemeketans. Excited to put it to more use.

    If it ain't broke don't fix it!

    • Familiarity: I've used it several times

    This ATC is just about as standard as it seems to come. Great for beginners to intermediate climbers. Easy and intuitive to use, just keep that break hand strong! The only down side for me is that there aren’t cleats which, not sure how much they do, but they make me feel better.

    Not Dead Yet

    • Familiarity: I've put it through the wringer

    I've been using this religiously and it has kept me (and my friends) alive and well thus far. It's simple to use, doesn't catch, isn't heavy to wear on your harness if you're climbing, good for beginners, and is overall a great piece of atc.

    You can't go wrong with a classic

    • Familiarity: I've put it through the wringer

    This belay device is an essential to any climber of any skill level, it can do pretty much anything and it does it well, rappelling with this is really easy and belaying is great and even though using a gri-gri offers better peace of mind its still a great tool to belay with, my one complaint is if you're belaying or rappelling with a thick rope, I often times have a bit of trouble getting the rope threaded in. all in all, its an amazing tool and everyone should have one

    Good simple belay device

    • Familiarity: I've put it through the wringer

    I needed to replace an old ATC. I have tried a number of other devices but I wanted something simple and light for multi pitch climbs. This device is perfect. Also I find it very easy to rappel with. Buy it you will like it!!

    Rock on!

    • Familiarity: I've used it several times

    Just getting into climbing, I didn't know what I was actually getting. When it came in, I was tripping out because there were no teeth! But further knowledge, it's the design that makes it without the teeth as other ATC's. Regardless, this product is fantastic. Light weight, great color, and get's the job down without anyone dying.

    Ol' Faithful

    • Familiarity: I've put it through the wringer

    No one can go wrong with the ATC! Whether this is your only belay device or you have everything from here to a Grigri, this guy should be in your collection! I've cycled through these bad boys and I've never had a single issue because they're simple and straightforward - just as they should be!

    Great for beginners

    • Familiarity: I've used it several times

    Bought this when my boyfriend and I started rope climbing. Easy to use even for beginners, and highly functional, this is the best belay device for anyone not worried about extra bobbles distracting them from the pursuit of a long day of belaying.


    • Familiarity: I've put it through the wringer

    I prefer this ATC to the more fancy ones for belaying. I think you can lower the climber with a bit more consistency, so he/she doesn't get a bouncy ride back to the ground. Other than that it works well, provides a lot of friction, and is easy to get ropes of all sizes into.

    Does The Job

    • Familiarity: I've put it through the wringer

    Been using this ATC for a year now and it works well. Feels solid, looks cool, and works as it should. Friction could be better, but if thats what you're after, just spend a few more bucks and get the ATC-XP. Would recommend to a friend.

    Everyone should have one

    • Familiarity: I've put it through the wringer

    I bought this to replace an Black Diamond ATS I had purchased more years ago than I care to admit. If this one is anything like the last one I purchased, top quality and will last for years.
