1st και 2nd Stage Regulators

The Fusion 72X scuba diving regulator guarantees high performance and excellent durability. The 72X first stage is forged from brass, chrome-plated and finished with a 'pearl' surface. This processing makes it highly resistant to abrasion, while offering a unique and elegant appearance. The Fusion second stage has high thermal conductivity properties, making it ideal for use in very cold water. Learn More

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.

Simple and reliable, the air balanced C370 delivers consistent airflow, ease of use and dependability, making it just the ticket for recreational divers in general, and dive travelers in particular.  Thanks to its compact size and light weight, this is also a fantastic regulator for our female divers and smaller sized divers. With any of these regulator systems in your dive bag you'll be ready to hit the road.

Together they create a no-nonsense air delivery system that delivers big performance in a small package.

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.

The ac25 is the third generation of cressi’s ip adjustable balanced piston first stage. It features 2 high-pressure ports and 5 lowpressure ports. 4 low-pressure ports are located on a rotating turret that ensures that regulator and instrument connections are always in the right position. The fifth port is a co-axial hi-flow port and is located at the top of the turret. The rotating turret swivels on 360° axis and features 5 low-pressure ports designed to allow the use of more connections without interfering between them. It features the external direct ip adjustment system that can be set using a simple allen key. The hi-flow conic shape filter is the same for int and din. The spring and the spring bush are coated preventing rust. Its technologically advanced design delivers consistent intermediate pressure and high performance even with low tank pressures. The ac25m it features a matte finish, in gun metal-coated brass. It is combined with the master cromo, the pneumatic balanced 2nd stage that features an elliptical shape and a lateral knob for venturi adjustment Learn More

Performance, ergonomic reliability, and ease of maintenance make this regulator a product for true diving professionals. Instructors, guides, dive operators, and researchers will find the answer they need in the Master Ellipse. The first stage stands out from the range of Cressi balanced diaphragm regulators because the mechanism is arranged on an axis perpendicular to the axis of air entry, creating a "T" shape. The advantages of this particular design include better arrangement of the hoses and less space occupied (especially in SC versions for cold water). What's more, this makes it remarkably easy to inspect and access the mechanism to improve maintenance and calibration operations, it uses a larger, high-efficiency conical filter, and the valves are arranged more easily on the tank. The metal body is protected on the surface by a special treatment called PVD (Physical Vapor Deposition), which compared to traditional chrome coatings is exceptionally resilient to the mechanical and chemical wear caused by dives. The DIN fitting has a generous metallic handwheel to make it easier to use in extreme conditions. The Master Ellipse second stage has installed the exceptional and proven Cressi balanced valve to ensure minimum inhalation effort. This valve is paired with a body with metallic parts treated in PVD. What's more, the knob for adjusting inhalation effort is made of a metallic material to guarantee reliability and resistance to blows and scratches. Learn More

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.
