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 Scubapro D420 regulator has a better airflow profile compare to standard 2nd stage designs with a low work of breathing rating. It features a brand new balanced valve inside a housing supported by a full metal structure and allows for easy left or right handed hose routing for maximum flexibility.

Scubapro D420 Second Stage Regulator

 

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.

D420 Second Stage

  • NEW. Uniquely shaped fiberglass-reinforced nylon casing carries on the D-Series heritage with the latest advances in breathing performance technology. 
  • NEW. Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow with a natural smoothness comparable to breathing on the surface. 
  • NEW. 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. 
  • NEW. Casing design features inner winglets that direct airflow towards the exhaust valve, creating a dramatic improvement in exhalation effort. 
  • NEW. 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 press, 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. 
  • CE certified according the latest EN250A European Standards for all diving conditions, including extreme cold water. 
  • Weight (without mouthpiece): 216g. 
  • Airflow at 200bar: 1800 l/min - 64 SCFM.

Scubapro MK25 EVO First Stage:

Scubapro MK25 EVO First Stage RegulatorWith the introduction of the new patent-pending Extended Thermal Insulating System (XTIS), the Scubapro MK25 EVO first stage lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow - 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 its freezing resistance 30 percent over the old MK25 without compromising breathing performance. This makes the MK25 EVO the ultimate do-it-all first stage for all water temperatures.

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.

  • 300bar DIN connection.
  • Weight: DIN 300 572g
  • Airflow at 2900psi (l/min/SCFM): >8500/301.
  • Intermediate pressure 9-9.8 bar.

Scubapro D420 Mk25 Evo regulator set

*Most of our divers prefer 300 bar DIN fitting on the 1st stage regulator which attaches to the tank valve. A DIN regulator has a threaded post which screws into the inside of a DIN valve tank and has no additional metal or braces that run behind the valve. This, together with the position of its o-ring, creates a more secure seal on the tank. YOKE (or A-Clamp) 1st stages have an oblong metal brace that completely encircles the tank valve when in place and is screwed down on the tank valve when the yoke screw is tightened. Both regulators seal to the scuba tank by means of an o-ring where the o-ring on a Yoke valve is in the tank valve itself as opposed to DIN regulators that have the own o-ring. DIN fittings are commonly accepted as being more secure but Yoke valves are common throughout North America and recreational tourist destinations. A DIN regulator can be adapted to Yoke valves by using an A-clamp adapter for travel.
