Black Diamond has made an essential piece of climbing gear essentially better.

The Black Diamond ATC-XP is a true variable-friction belay and rappel device with wicked holding power. With the ATC-XP, a climber can control how much friction they want while belaying or rapping, which in turn means greater control with multiple rope diameters. Ice climbing with an 8.1mm rope? Use the ATC-XP in high friction mode, pulling the rope over its contoured teeth. Rappelling with a fuzzy 11mm down a granite slab? Use the device in regular friction mode. An extended central web keeps 'biners and ropes properly oriented and reduces kinking. This Black Diamond belay device is such a favorite among climbers that it won the Climbing Magazine Editor's Choice Award. *Assorted colors.

the ATC

The black diamond ATC is one of the best belay devices I have ever used. The device is simple and yet very effective. The Black Diamond ATC is easy to use. The ATC is a must have for all climbers.

great control

simple tool. have used with many rope diameters and in snow. teeth work well

No Complaints

It works great. The high friction side gives me a bit more control and options. I didn't really find any downsides to it.

$23.90 is the price of one single ATC-XP belay device. The picture is a stock photo showing the different color options.
I hope this helps.

Great Belay Device

Great price.

Bomb proof.

Great friction for belaying the big boys.

I have no problem belaying someone much larger than me with this device. For the kiddies, I simply flip it around and use the low friction side. Great product, definitely a great improvement on the standard ATC.

Will the teeth on this device reduce the life of my rope from continued use?

The teeth are smooth and rope wear won't be an issue at all. I suppose, theoretically, your rope is getting worn down by the friction of your gear (i.e. biners, belay device, etc), but at such a neglible rate that it would take much longer than the rated lifetime of your rope to create an issue. If you have rope wear issues, it won't be due to your biners or belay device...as long as you use them correctly, i.e. keep rope biners separate from bolt biners, etc. In other words, I wouldn't give a second thought to it.

Gets the job done, in style!

This is a great belay/rappel device for the price and it along the line of the new petzl reverso, but cheaper! It hold falls well with minimal slippage, but I do find that if you flip it around on the less friction side, it is a bit harder to control, but that is as expected.

Awesome ATC

It was my first atc that I have bought. I took it down several canyons a few weeks ago and loved it. It never caught and it was a very smooth ride. I heard about this product from a friend who is an experienced canyoneer, and I am very glad I took his recommendation.

It works

Pretty light, basic belay device. V groove works well with the option to reverse if your not a fan or dont need the extra grab

I'm still using the classic

I traded this in for a classic ATC. No matter which way I flipped the thing, the teeth always seemed catch the rope a little as I feed it... Just a preference thing I guess, the concept is pretty cool, just didn't work for me.

Great for cragging.

I like this better than the regular atc because I like having the option of using it in high friction mode for skinny ropes. But if you climb multi-pitch routes I would upgrade to the atc guide because it has the option of using it in self locking mode which this (atc-xp) does not.

What are these grooves for?

Black Diamond has proved themselves bomber over and over again. But ... the v grooves are worthless. They just dig into your rope decreasing your rope life. Buy a Trango B-52.

Great device

I always feel good climbing above one of these. Catching is easy with it and makes soft catches easy. I would use this device over the GriGri any day, unless you can't see the climber or it is a super long pitch that is longer than your attention span.

The device does heat up quite a bit after a long rappel, not sure if this has any real damaging effects on a rope..?

Just the way it should

This has good teeth and is slick. No complaints. Tried other brands but BD is it!

Great Device

The XP does exactly what it is supposed to do...the teeth on the belay add just the right amount of friction to any size rope in order to help you catch a fall or slow rappels. As long as the device is used properly, it will function perfectly.
