ATC-Pilot Belay Device

Rest assured that Black Diamond's ATC-Pilot Belay Device will help you catch whipping lead climbers like any other assisted braking device. Unlike most assisted braking belay devices, the ATC-Pilot doesn't use any moving components to ensure a secure brake; instead, the device's unique geometry makes the rope pinch itself whenever the rope tugs too hard on the climber side, ensuring a naturally reliable catch every time. This is Black Diamond's first attempt at making an assisted braking device with increased security and safety, and climbers can't help but admire its compact, lightweight, sleek design that could only come for Black Diamond.

Easy to use but wish they had more color options

I absolutely Love my ATC Pilot belay device. I use it constantly and it makes belaying so smooth. The only thing I wish is that it came in different colors, preferably something pastel.

Works well and is extremely light

This device works awesome and is super light compared to other products. The only downside I found is I have problems lowering the kids because of the amount of friction. It works best when there is a little bit of weight on the rope.

Great for ice climbing

Icy ropes are scary to me, so this device is great, for assisted breaking and lowering on ice climbs.

great for use with cold or wet ropes

I've used it several times

This was recommended to me for use ice climbing, when ropes can become wet and/or frozen. I love it! the auto locking feature is responsive, rope feeding is smooth and intuitive.

Easy belay device to use, small and convenient, and locks well for leader falls.

Passive braking, easy paying

It is what it says it is. Passive braking belay device. I feel like the choice to put plastic on it detracts from the elegance of the design and adds a weak point to a solid idea.

Extremely light

This purchase was a trial to give the new pilot a try. I like the light weight aspect to it and the assisted braking is a good tool for some friends who are still working on belaying skill.
