Black Diamond ATC Pilot Review

The Black Diamond ATC Pilot is a "geometry assisted" belay device for ropes in the 8.7 to 10.5 mm range. When the rope is weighted the angle of the device changes, locking the rope down, though, as we mentioned above, you still need to keep your brake hand on the rope. Speaking of your brake hand, it's not right-hand dominant like most other assisted belay devices, so left-handed climbers can belay with it the "opposite" way if that feels more natural to them.

Performance Comparison

Catch/Bite

We liked the catch on this device and felt like it provided almost the same security as the active locking devices. There's little to no slippage like you experience from the tube style devices, and should you get knocked around in the fall you can be reasonably sure that the mechanism will engage completely. We did encounter some creepage one or two occasions, though we found it tough to replicate them. Because of variances in rope diameter, belay carabiners, and friction from quickdraw placement or route wandering, it is hard for us to say for certain when or how this device is likely to creep, though it mostly happened in gym scenarios with little friction in the system. BD states that the Pilot should only be used with larger Type H or HMS carabiners, and always on the larger side if using a divided carabiner like the Gridlock.

Lowering/Rappelling

We liked the lowering function of the ATC Pilot better than the other passive assisted braking devices we compared it to. The curved plastic housing on the Pilot was more comfortable to hold onto than the sharp metal edges of other devices, and the rope stayed in the shorter track better. Unlike tube-style devices, where you have to loosen your grip on the rope for it lower, the Pilot requires you to pull back on the device to disengage the camming function. If we were solely choosing one of these passive belay devices for top roping, we'd choose the Pilot since we liked how it lowers the best. As for rappelling, Black Diamond doesn't say that you can't do it, though it would only work for single rope rappels, which is not always useful.

Feeding Slack

Here is where we were underwhelmed with the performance of the Pilot. The Pilot feeds out slack in a similar manner as most other passive assist devices. You have to exert upward pressure with the thumb of your brake hand to "unlock" the device while pulling out slack with your other hand. The Pilot required more thumb pressure than others we compared it against (and more constant pressure throughout a belay) to get the rope to pay out smoothly. If we weren't constantly pushing the device out to the maximum amount, it would start to lock up on us. Some other devices didn't require as much exertion.

Weight/Bulk

The Pilot weighs 3.2 ounces (same as the ATC Guide) and doesn't take up much room in your pack. It also has a relatively small profile, so weight and bulk are no reason not to consider owning one.

Auto block (resistance belaying a second)

The Pilot is not made for belaying a second off an anchor, so we could not test or rate it for this category. If you are looking for a device that can do this, the Edelrid Giga Jul is our Top Pick for Multi-Pitch Climbing.

Value

While this device is not particularly expensive, especially when compared to the cost of most active assist belay devices, it is also not as cheap as regular auto-block or tube-style devices. It is a bit of a one-trick pony though, and you'll likely get more versatility out of a device that can handle two ropes.
