Combining the iconic design of the original D-Series regulators with the latest advances in breathing performance technology, SCUBAPRO engineers have created a 21st century regulator in terms of quality, reliability, performance and style. The new D420 features a brand new balanced valve inside a housing supported by a full metal structure. Called the Progressive Flow Control Valve, it is able to deliver abundant airflow for the best breathing performance, with a natural smoothness comparable to what you might experience breathing on the surface. The uniquely shaped fiberglass-reinforced nylon casing is ultra-durable and allows the LP hose to be connected on either the right or left side for maximum rigging flexibility.
Uniquely shaped fiberglass-reinforced nylon casing carries on the D-Series heritage with the latest advances in breathing performance technology.
Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow with a natural smoothness comparable to breathing on the surface.
Dive/pre-dive system includes a switch on the top of the case with a thumb tab for adjusting the direction of airflow right out of the valve.
Casing design features inner winglets that direct airflow towards the exhaust valve, creating a dramatic improvement in exhalation effort.
Diaphragm is located in the lower section of the casing to take advantage of the pressure gradient in the upright position, making breathing even easier.
Reversible hose attachment allows for either left- or right-side LP hose connections for maximum rigging flexibility.
Large purge button is easy to reach and depress, with or without gloves.
Exhaust tee is compact and efficiently deflects bubbles from the diver’s view while enhancing ease of exhalation.
Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest.
Air balanced flow-through piston first stage design delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.
Patented XTIS (Extended thermal Insulating system) fully insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold-water conditions without compromising breathing performance.
Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
Two opposing high-pressure ports allow the first stage to be positioned either up or down.
Four high-flow and one axial super high-flow low pressure ports on a swivel turret maximize hose routing options.
CE certified according the latest EN250A European Standards for all diving conditions, including extreme cold water.
The MK11/C370 is a great choice for dive-trekkers. The balanced diaphragm MK11, with its chrome-plated brass body specially designed to reduce size and weight, is an ideal travel companion. Its system features internal parts that are sealed from the elements. The new C370 brings forth the best features of its predecessor, the C350, while adding a balanced valve to its design. Its new exhaust tee, based on the S620 Ti’s design, contributes to a 10% improvement in work of breathing over the C350. With this regulator system in your dive bag you’ll be ready to hit the water.
SCUBAPRO combines its premium high-performance MK25 EVO first stage with its latest high-performance S620 Ti second stage to create a winning all-purpose, all weather regulator system. The MK25 EVO offers excellent resistance to freezing, superb inhalation sensitivity and instant delivery of air on demand. The S620 Ti embraces the best features of SCUBAPRO's renowned S600 in an upgraded, state-of-the-art design. Smaller and lighter than the S600 but using the same-sized diaphragm, the S620 Ti delivers effortless airflow under all dive conditions. The full titanium inlet tube is ultralight, the large purge button improves water circulation, and the reengineered exhaust tee assists in reducing work of breathing.
The ultra-compact MK21/C370 regulator system delivers the ideal blend of comfort and performance. About 20% smaller than SCUBAPRO’s flagship MK25 but benefitting from the same core technology, the MK21 features a modern, cutting-edge design whose size and weight make it an excellent choice for travel divers. The C370 brings forth the best features of its predecessor, the C350, while adding a balanced valve to its design. Its exhaust tee, based on the S620 Ti’s design, contributes to a 10% improvement in work of breathing over the C350. Together they create a no-nonsense air delivery system that delivers big performance in a small package.
