The Wild Country Revo has multiple unique features that make it the safest locking and only auto-locking belay device ever designed for climbing. It's the only assisted locking belay device that's bi-directional, meaning you can load climbing ropes in either direction, which eliminates one of the most common causes of belay-related accidents. Wild Country's equally innovative panic-proof locking mechanism doesn't require unlocking to actually lower climbers like so many assisted belay devices do. This device is also incredibly intuitive to anyone who already practices the proper belay method, meaning it's easy to go from a tube-style belay device to the Revo without changing belay habits.
