Scubapro Mk19 Evo D420 S270 with Octopus Set

With the introduction of the Scubapro Mk19 EVO D420/S270 Regulator Set, engineers have combined the iconic design of the original D-Series second stages with the latest advances in breathing performance technology. They then teamed it with the MK19 EVO balanced diaphragm first stage to creating a 21st-century regulator in terms of quality, reliability, performance and style.

The D420 features a 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 fibreglass-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 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 concept that gives the D420 its unique face.

Teamed with the compact, lightweight MK19 EVO offers an environmentally sealed system and a dry ambient pressure chamber, plus a user-friendly LP port swivel turret, this regulator system is uniquely well-suited to handling cold water and the harsh diving conditions often encountered by technical divers. This makes the MK19 EVO/D420 more tech-driven than the MK25 EVO/D420 while serving avid divers and SCUBAPRO brand enthusiasts everywhere.

FIRST STAGE Features:

• Designed to be the ultimate first stage for cold water or contaminated diving conditions.
• Its design makes it substantially smaller and lighter than the original MK19.
• Air-balanced flow-through piston in a chrome-plated marine-grade brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• An environmentally sealed system prevents water and pollutants from fouling the inner mechanism.
• Its dry chamber is equipped with a double spring, making it more compact and reliable.
• Two opposing high-pressure ports allow the first stage to be positioned either up or down, plus provide for an optimum hose/transmitter layout.
• The swivel turret comes with four High-Flow LP ports plus one axial Super High-Flow LP port to maximise hose routing options.
• Compact size, lightweight and superb breathing performance continue in the best SCUBAPRO regulator tradition.
• The ideal first stage for recreational, technical, professional and military divers.
• Weight: INT 232, 885g; DIN 300, 665g
• Airflow at 2900psi/200bar: (l/min/SCFM): >6,900/244
• Intermediate pressure (psi/bar): 133-142/9.2-9.8

SECOND STAGE Features:

• Uniquely shaped fibreglass-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.
• Its 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.
• Its casing design features inner winglets that direct airflow towards the exhaust valve, creating a dramatic improvement in exhalation effort.
• The 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.
• A large purge button is easy to reach and depress, with or without gloves.
• The exhaust tee is compact and efficiently deflects bubbles from the diver’s view while enhancing the 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.

OCTOPUS S270 Features:

• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• Lightweight casing, made of a fibreglass-reinforced nylon core and a special PU outer layer, is extremely durable plus helps reduce jaw fatigue and improve diving comfort.
• Technopolymer plastic barrel with a metal thread and a balanced valve helps save weight and provides a surface that ice crystals can’t grab onto when diving in extremely cold water.
• The dive/predive switch prevents free flows when not being used.
• The exhaust tee is compact and very efficient in minimising exhalation effort.
• The compact Hi-Flow mouthpiece is comfortable, made with FDA-approved silicone and features a large cross-section to maximise airflow.
• High-viz yellow front cover stands out, making it easy to spot when needed.
• The high-viz yellow super-flow hose is 39in/1m long with an oversized bore that allows more air to flow on each inhalation.
• CE certified to the latest EN250A European Standards for all diving conditions, including extreme cold water
