Scubapro Regulator Pack MK25 /A700 + S270

First Stage

• Air-balanced flow-through piston housed in a chrome-plated marine-grade brass body, delivering constant and effortless airflow regardless of depth, tank pressure, or breathing rate.

• Patented XTIS (Extended Thermal Insulating System) thermally insulates the internal mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold conditions without compromising breathing performance. Key insulation components are highlighted in blue.

• Spring insulating coating, body insulating bushing, anti-freeze cap, larger body and cap thread all work together with the XTIS to enhance cold-water performance.

• Anti-freeze protection significantly increases breathing reliability when diving in extremely cold water temperatures.

• Two opposing high-pressure ports allow the first stage to be positioned either upward or downward.

• Four high-flow low-pressure ports and one axial super high-flow low-pressure port on a swivel turret maximize hose routing options.

• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.

• The DIN version features a dual-compound handwheel with an ergonomic shape and soft grip mounted on a rugged black nylon frame.

• Intermediate pressure: 9.2 – 9.8 bar

• Weight: INT 232 – 790 g | DIN 300 – 570 g

Second Stage

• Air-balanced valve smooths inhalation effort at varying depths and supply pressures.

• Rugged full-metal case, front cover, and valve housing (barrel) are designed to withstand years of aggressive diving.

• Metal construction allows the use of a larger diaphragm inside a compact housing, increasing breathing sensitivity.

• User controls include a diver-adjustable inhalation effort knob and a coaxial-flow VIVA (Venturi-Initiated Vacuum Assist) lever.

• Super-flow hose with an oversized bore allows more air to flow with each inhalation.

• Ultra-comfortable orthodontic mouthpiece that is easy to grip without restricting airflow.

• CE certified according to the latest EN250A European Standards, suitable for all diving conditions, including extreme cold water.

• Weight (without mouthpiece): 261 g

Octopus

• Air-balanced valve smooths out inhalation effort at varying depths and supply pressures.

• Lightweight casing made of fiberglass-reinforced nylon core with special PU outer layer is extremely durable, reduces jaw fatigue, and improves diving comfort.

• Technopolymer plastic barrel with metal thread and balanced valve saves weight and provides a surface that ice crystals cannot grab onto in extreme cold water.

• Dive/predive switch prevents freeflows when not in use.

• Compact and efficient exhaust tee minimizes exhalation effort.

• Compact Hi-Flow mouthpiece is comfortable, made with FDA-approved silicone, and features a large cross-section to maximize airflow.

• High-visibility yellow front cover stands out, making it easy to spot when needed.

• High-visibility yellow super-flow hose, 1 meter long, with oversized bore allows more air to flow on each inhalation.
