Cressi AC5 Zen
Inspired by the state of calm and serenity when our actions are guided by intuition rather than conscious effort, the Zen second stage is optimized for maximum airflow in an ultralight, compact package. It includes an adjustable Venturi and is paired with an AC5 piston first stage for reliability and durability. A bayonet-style opening on the second stage allows for tool-free disassembly, making Zen the art of regulator maintenance.
