    How to make the best ATC better.

    The ATC Guide Belay Device is already worthy of any climber's arsenal, but Black Diamond made it even better for alpinists and crag-stars alike. It still transcends the tube/auto-blocking category, allowing for a standard belay as well as belaying one or two climbers off anchors. Black Diamond upgraded it with machined windows for a lighter weight, and the larger auto-block release accepts smaller carabiners for a smoother and more dependable operation.

    Worked Great

    • Familiarity: I've used it once or twice and have initial impressions

    I got this for canyoneering, and was very pleased with it. It works great for several situations where you need more or less resistance. It doesn't have the smoothest descent when you have a thick heave rope pulling from below, but I got used to it. Also seems like it will hold up well.

    Buy this over the XP

    • Familiarity: I've put it through the wringer

    If you think you might ever get into multi-pitch or have friends that even think they might. Get the Guide instead of the XP so you won't have to buy two devices.

    Great but....

    • Familiarity: I've put it through the wringer

    Awesome ATC, I still prefer Black diamond out of blind brand loyalty but after heavy use in the last 3 weeks it has worn a lot where the teeth are basically gone. Great for repelling, multi pitch trad, definitely great for a lot of technical climbs, but would not trust in 4-6 months. Also its super light at 88 grams which makes it so ideal.

    Absolute Classic

    • Familiarity: I've put it through the wringer

    Best belay I've used, hands down. Weighs a bit more than the competition, but the quality and durability on this thing is unmatchable right now, especially when you take the price into consideration. Go with this, you won't go back.

    Beats the competition

    • Familiarity: I've put it through the wringer

    I’ve used this and the Petzl Reverso for a few years now. The BD is heavier, but more robust. It handles thicker ropes better, but I’ll use my Reverso with my 8mm doubles. I definitely prefer the way the BD hangs in guide mode to the Reverso. (Facing you as opposed to the Reverso being 90 degrees off) I find rope management easier this way.

    Great for single or multipitch routes. belay from the top, bottom, hip, however ya want. no assisted breaking but able to run a double rope repel. Also grea for canyons.

    THE Belay Device to Get

    • Familiarity: I've put it through the wringer

    Having climbed on this thing for the last two years, I have nothing but good things to say. It has phenomenal breaking power, lowers climbers smoothly, and is easy to rig up for rappels. The device makes belaying from the top smooth, the guide loop is large enough to accept most carabiners, and the auto bloc release loop makes lowering climbers in guide mode easy. Yes, it could be an ounce lighter, but how much difference does that make with a full rack and rope? I'd rather have the extra ounce and a device that excels at catching a fall and will last for years to come.

    Trust in BD

    • Familiarity: I've put it through the wringer

    I'm a big fan of my guide, I use it for rappels and belaying on multipitch. It does exactly what it's supposed to, maintains a respectable weight for how durable it is, and is a brand I always feel I can trust.

    Love it, great ATC!

    • Familiarity: I've used it several times

    Use this for mostly belaying top rope in or outdoors and love it! I have been using my Evolution Velocity Sharma Edition Climbing Rope - 9.8mm with it and it flows great through it!

    as advertised

    • Familiarity: I've used it several times

    I am just getting into climbing but many people encouraged me to go with this. So far so good. Everything has worked smoothly allowing me to focus on developing my skills with no concerns about my gear.

    Nothing better

    • Familiarity: I've put it through the wringer

    Love using this ATC. It's incredibly reliable, durable, and doesn't bind up. I've used this style for years, and plan to continue using for years to come!

    The only reason you shouldn't be using this plaquette is because you are taking out your silly-skinny twins, and choose your Micro-Jul for the day. I've used about every obscure plaquette variation, and this one wins. People have already covered the main benefits: works well with fatter ropes, durable, less friction in guide mode. I've used it with single ropes from 9.1-11mm, and it worked great for all of them. The friction difference in guide mode compared to the Reverso specifically is very noticeable for me, and that alone would sell me on it. I'm also a fan of the "vertical" orientation of the guide eyelet, compared to the "horizontal" layout of European models (Reverso etc), but that's just preference. The weight difference between devices is negligible, you only carry one, it isn't going to add up like cams/'biners. It takes a beating, and shows minimal wear. The one pictured I got right after BD released their updated version, and have abused it since I got it. Nothing bad to say. It works. Wouldn't mind seeing the guide version in that snazzy blue the XP comes in though.

    Coming from a Petzl

    • Familiarity: I've used it several times

    Its bigger, but i dont notice any weight difference. I thought it would work a little better with my rope (9.8) but it seems the same as the Petzl. However, its a different metal, and supposedly lasts longer, so we'll see.
