1st και 2nd Stage Regulators

TOUGH, RELIABLE, ECONOMICAL

 

It's the perfect go-anywhere reg for both new divers and veterans who like to keep their diving simple and fun.

For decades the classic downstream piston MK2 has been diving's go-to workhorse first stage. It is reliable, easy to use and won't put too big a dent in your pocketbook, and now it's more versatile than ever.

The new MK2 EVO comes with the patent-pending Extended Thermal Insulating System (XTIS) that lets you enjoy an ultra-fast breathing response and maximum airflow with minimal effort -- regardless of how cold the water is. The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing freezing resistance by an average of 50 percent over the current MK2.

The MK2 EVO is also more compact than the standard MK2, yet has a bigger piston that pumps out 15 percent more airflow from a smaller package. So you can expect top-notch breathing performance whether you're reef diving in the warm Caribbean or wreck diving in the chilly Great Lakes.

The R095 is a modern second stage design based on the heritage of the time-honored R190. The R095 combines a classic downstream valve with a large diaphragm, functional purge button for smooth and easy operation.

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. A new dive/pre-dive system includes a switch on the top of the casing with a thumb tab for adjusting the direction of airflow right out of the valve. The highly efficient purge button is a technical jewel based on a new concept that gives the D420 its unique face. Teamed with the venerable MK25 EVO balanced piston first stage, this is a regulator system purpose-designed for today’s avid divers and SCUBAPRO brand enthusiasts everywhere. Learn More

Technical Information

MK25 EVO First Stage:

 

• Air-balanced flow-through piston design provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Patent-pending XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the current MK25 without compromising breathing performance.
• New spring insulating coating, body insulating bushing (non-metal cylindrical interface separating metal parts from water), anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance. (Key insulation system components are visible in blue.)
• Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
• Two high pressure and five high-flow low pressure ports on a swivel turret maximize hose routing options.
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
• Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
• Weight: INT 232 (oz/g): 29.1/825; DIN 300 (oz/g): 20.9/592.
• Airflow at 2900psi (l/min/SCFM): >8500/301.
• Intermediate pressure (psi/bar): 130-142/9-9.8.
