Black Diamond ATC-Pilot Belay Device

Black Diamond

The Black Diamond ATC-Pilot is aimed at climbers who belay frequently and want an assisted-braking device that adds a margin of safety without the bulk or price of a full auto-locking system. It bridges the gap between a passive tube device and a full-assisted locker, making it a practical choice for sport and multi-pitch leaders and their belayers. Priced at €52.49, it sits in the mid-range segment where extra safety features start to justify the cost.

How to choose a belay device

A belay device is one of the few pieces of gear that sits directly between your partner and a ground fall. Choosing the right one is less about brand loyalty and more about matching the device type to your climbing context, experience level, and the ropes you already own.

Key criteria to consider

Device type: Tube devices (passive) are the most versatile and work in almost any situation. Assisted-braking devices add a mechanical camming action that helps lock the rope under load — useful when belaying a lead climber, especially at distance. Auto-locking devices (e.g. Grigri-style) provide the strongest passive brake but are heavier and less suited to rappelling or guide mode.
Rope compatibility: Always check the rope diameter range stated by the manufacturer. A device optimised for 9–10.5 mm ropes will not brake efficiently on an 8.5 mm skinny rope, and vice versa. If you climb on different ropes, pick a device with a broad diameter range.
Use case: Single-pitch sport climbing, multi-pitch trad, alpine routes, and indoor climbing each have different demands. Guide mode (available on some tube devices) lets you belay a second hands-free on multi-pitch — a genuine practical advantage, not a gimmick.
Weight and bulk: Relevant mainly for alpine and multi-pitch objectives. For indoor or single-pitch sport climbing, a few extra grams are irrelevant.
Price: Passive tube devices typically cost under €30 and cover most needs. Assisted-braking devices run €40–€70. Budget accordingly, but do not cut corners on a safety-critical item.

Advice by level

Beginners benefit most from a simple tube device: fewer moving parts mean fewer things to misuse while still learning technique. Take a course or climb with an experienced mentor before relying on any device independently.

Regular sport climbers who belay leads frequently should consider an assisted-braking device. The extra braking assistance is most relevant when catching unexpected falls or when fatigue sets in during a long session.

Multi-pitch and alpine climbers should prioritise a tube device that offers guide mode. Versatility and low weight matter more at this level than assisted braking, since rope management in complex terrain requires full manual control.

Common mistakes to avoid

Using the wrong rope diameter: Pairing a device with an out-of-range rope diameter reduces braking friction and is a genuine safety hazard. Always verify compatibility before you clip in.
Treating assisted-braking as fully automatic: An assisted-braking device is not a hands-free system. The brake hand must always remain on the rope — the device is a backup, not a replacement for correct technique.
Ignoring wear: Rope drag wears grooves into aluminium devices over time. Inspect the rope channel regularly; a heavily grooved device should be retired.
