The Hollis 200LX + DCX regulator is designed for extreme environments, delivering reliable performance for scuba and diving gear setups. Backed by four decades of life-support manufacturing, this flagship regulator offers flexible configuration with a reversible hose design to suit different preferences and gear layouts.

Paired with the DCX first stage, it features a pneumatically balanced PVD plated brass valve for smooth, effortless breathing in demanding dive conditions. The Reversible demand valve allows conversion between right-handed and left-handed hose configurations, while the Diver adjustable inhalation knob lets divers tailor inhalation effort. An adjustable Dive/Pre-Dive switch with a large Venturi lever and soft rubber grip ensures easy, precise control underwater. Ergonomic exhaust channels direct bubbles away from the field of view, reducing exhaust effort, and the improved orthodontic mouthpiece with dual color tabs enhances comfort during long dives.
