How Was the ATC Belay Device Designed?
The first belay device was known as the Sticht plate. It provided many advantages to the climbers, but there were some faults also.
When the climbers pulled hard on the ropes, the mechanism jammed due to the carabiner locked on the plate. The problem was not solved even after the introduction of the micro-belay plates.
The Diamond ATC devices solved all these problems. They improved the design by making some structural changes and durability enhancements.
They changed the location of the slots and made them half inch higher than the biner location. This enhancement allowed the rope to handle more pressure.
The climbers can pull the rope harder without fear of mechanism locking. They also improved the rope design by adding a sharper end to the rope.
It allowed the climbers to control the rope better due to more friction on the rope. These design enhancements increased the climber’s trust in the ATC devices.
The Original ATC Belay Device
It is only possible to climb comfortably when you trust your ATC device. You can use the Black Diamond ATC device because it has a history of safe climbing. T
hey have decades of experience in ATC device manufacturing as they produced their first devices in the 90s. Most people trust the original ATC belay devices from the Black Diamond.
You can get the Black Diamond ATC devices in two versions.
You can get the original ATC or the ATC-XP. Most people buy the original version because it is for rock climbing.
When you have to climb the ice, you need the ATC-XP version. The life of a climber depends on the climbing gear.

Should You Use the ATC-XP for Canyoneering?
You can use the ATC-XP for rappelling canyons, but only for the class-A and class-B canyons. It is not suitable for the class-C canyons.
You must know the classification of the canyons to understand the suitability of the ATC-XP. The class-A canyons are dry as you can use the ATC-XP in them.
Special care is needed for the class-B canyons because you have to deal with the wet surface and ice. ATC devices are also suitable in canyons with ice.
When you reach the class-C canyon, you need specialized equipment to work in running water. It is crucial to check the condition of the canyon before choosing your climbing and rappelling gear.
The chances of falling increase when you use the wrong type of ATC for the canyons. Original ATC is not designed for the smooth surfaces of the canyons.
