With the introduction of the D420, SCUBAPRO engineers have combined the iconic design
\nof the original D-Series second stages with the latest advances in breathing performance
\ntechnology. They then teamed it with the MK19 EVO balanced diaphragm first stage to create
\na 21st century regulator in terms of quality, reliability, performance and style. The D420
\nfeatures a balanced valve inside a housing supported by a full metal structure. Called the
\nProgressive Flow Control Valve, it is able to deliver abundant airflow for the best breathing
\nperformance with a natural smoothness comparable to what you might experience breathing
\non the surface. The uniquely shaped fiberglass-reinforced nylon casing is ultra-durable
\nand allows the LP hose to be connected on either the right or left side for maximum rigging
\nflexibility. A dive\/pre-dive system includes a switch on the top of the casing with a thumb tab
\nfor adjusting the direction of airflow right out of the valve. The highly efficient purge button
\nis a technical jewel based on a concept that gives the D420 its unique face. Teamed with the
\ncompact, lightweight MK19 EVO offers an environmentally sealed system and a dry ambient
\npressure chamber plus a user-friendly LP port swivel turret, this regulator system is uniquely
\nwell-suited to handling cold water and the harsh diving conditions often encountered by
\ntechnical divers. This makes the MK19 EVO\/D420 more tech-driven than the MK25 EVO\/D420,
\nwhile serving avid divers and SCUBAPRO brand enthusiasts everywhere
\nMK19 EVO FIRST STAGE
\n\u25ca Designed to be the ultimate first stage for cold water or contaminated diving conditions.
\n\u25ca Its design makes it substantially smaller and lighter than the original MK19.
\n\u25ca Air balanced flow-through piston in a chrome-plated marine-grade brass body provides
\nconstant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
\n\u25ca Environmentally sealed system prevents water and pollutants from fouling the inner
\nmechanism.
\n\u25ca Its dry chamber is equipped with a double spring, making it more compact and reliable.
\n\u25ca Two opposing high-pressure ports allow the first stage to be positioned either up or down,
\nplus provide for an optimum hose\/transmitter layout.
\n\u25ca Swivel turret comes with four High-Flow LP ports plus one axial Super High-Flow LP port
\nto maximize hose routing options.
\n\u25ca Compact size, light weight and superb breathing performance continue in the best
\nSCUBAPRO regulator tradition.
\n\u25ca Ideal first stage for recreational, technical, professional and military divers.
\n\u25ca Weight: INT 232, 885g; DIN 300, 665g
\n\u25ca Airflow at 2900psi\/200bar: (l\/min\/SCFM): >6,900\/244
\n\u25ca Intermediate pressure (psi\/bar): 133-142\/9.2-9.8
\nD420 SECOND STAGE
\n\u25ca Uniquely shaped fiberglass-reinforced nylon casing carries on the D-Series heritage with
\nthe latest advances in breathing performance technology.
\n\u25ca Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow with a
\nnatural smoothness comparable to breathing on the surface.
\n\u25ca Its dive\/pre-dive system includes a switch on the top of the case with a thumb tab for
\nadjusting the direction of airflow right out of the valve.
\n\u25ca Its casing design features inner winglets that direct airflow towards the exhaust valve,
\ncreating a dramatic improvement in exhalation effort.
\n\u25ca Diaphragm is located in the lower section of the casing to take advantage of the pressure
\ngradient in the upright position, making breathing even easier.
\n\u25ca Reversible hose attachment allows for either left- or right-side LP hose connections for
\nmaximum rigging flexibility.
\n\u25ca Large purge button is easy to reach and depress, with or without gloves.
\n\u25ca Exhaust tee is compact and efficiently deflects bubbles from the diver\u2019s view while
\nenhancing ease of exhalation.
\n\u25ca Super-flow hose features an oversized bore that allows more air to flow on each
\ninhalation.
\n\u25ca Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all
\nmouth sizes, from largest to smallest.
\n\u25ca CE certified according the latest EN250A European Standards for all diving conditions,
\nincluding extreme cold water.
\n\u25ca Weight (without mouthpiece): 216g.
\n\u25ca Airflow at 200bar: 1800 l\/min – 64 SCFM.
\nS270 OCTOPUS
\nThe S270 Octopus is tough, reliable, and easy to use. Its air-balanced design can be
\ncounted on to deliver top-notch breathing performance when you need it most.
\n\u25ca Air-balanced valve smooths out the inhalation effort when diving at varying
\ndepths and supply pressures.
\n\u25ca Lightweight casing, made of a fiberglass-reinforced nylon core and a special PU
\nouter layer, is extremely durable plus helps reduce jaw fatigue and improve diving
\ncomfort.
\n\u25ca Technopolymer plastic barrel with a metal thread and a balanced valve helps save
\nweight and provides a surface that ice crystals can\u2019t grab onto when diving in
\nextreme cold water.
\n\u25ca Dive\/predive switch prevents free flows when not being used.
\n\u25ca Exhaust tee is compact and very efficient in minimizing exhalation effort.
\n\u25ca Compact Hi-Flow mouthpiece is comfortable, made with FDA-approved silicone
\nand features a large cross-section to maximize airflow.
\n\u25ca High-viz yellow front cover stands out, making it easy to spot when needed.
\n\u25ca High-viz yellow super-flow hose is 39in\/1m long with an oversized bore that allows
\nmore air to flow on each inhalation.
\n\u25ca CE certified to the latest EN250A European Standards for all diving conditions,
\nincluding extreme cold water.<\/p>\n","protected":false},"excerpt":{"rendered":"
