Black Diamond ATC Guide
Available Colors / Styles
Whether your beat is alpine, mixed, sport, or ice climbing, the Black Diamond ATC Guide belay device offers a simple but versatile design to keep you moving through the vertical. The ATC Guide's self-locking capability comes in handy when you find yourself belaying a second, and its aggressive v-notch increases stopping and holding power. Speaking of versatility, this device handles ropes ranging in diameter from 7.7mm to 11mm so you can take it in the alpine as well as to the gym. But if you really want to know why Climbing Magazine gave it one of their prestigious Editor's Choice Award, you'll just have to try it for yourself.
Bottom Line: Utility without unnecessary bells and whistles.

Belaying off the harness with ATC Guide

Belaying off the anchor with the ATC Guide. Bird on a Wire, Joshua Tree NP

Although somewhat difficult to see the actual device, this is a nice illustration of how to use this to conveniently belay a second off of the anchor. Garrett is clipped to the shelf with a clove hitch on a locker. His 2nd is tied in to the end of the rope that extends off the right of the photo. The rope runs through the ATC guide in a manner such that if the 2nd were to weight the rope, it would pinch the brake strand against the device, holding the fall. The ATC guide is attached to the master point by its large carabiner hole, with one locking carabiner, and utilizes another to create friction.

i usually attach another biner which connects the master point and the other biner (the one rope is being pulled through) that way if s*** goes wrong you have two attachments to the anchor instead of just one

These ATC is a must have for any climber, i have the old version, but is the same the only difference is that the new one have a bigger hole to set up the decent system and it is made of a more resistant and lighter material. It works just perfect for any kind of belay, just the BEST!!
This is a better shot of my self belay..

I love this thing. It has endless capabilities and is a solid and secure platform for belay (either self,top rope, or seconds from anchor) and finds a lot of use on my rack.

I use a grigri a lot too... but believe it or not, I feel more secure with the ATC as it auto-locks fast and in most positions. I have inverted while locked off and it's held. I've just not tested it yet on an up side down fall yet... I will when I have my partner out with me and maybe a double prusik (actually I use the kleimheist knot for this setup) as it seems to slide easier, yet tighten when it should.
This is set for auto lock of my harness..

I use this setup for self belay. A prusik in case of a failure, and it works great. Just hard to lower with my 250 lbs on it. I have since hooked a nice lanyard for that issue.
Change me.
Research out-of-stock versions:
Best multi pitch belay ever
Once you belay someone from above using the auto-locking, masterpoint technique this bad boy allows for, you'll never use another belay device. That more...
Best Belay Device.
Black Diamond took a great belay device and made it BAD ASS!!!! I think this is the best Belay Device going....Light, and versatile... This thing will more...
