Scubapro Mk25 EVO/A700 carbon + S270 Octopus

Features:

• Handmade carbon fiber front cover, metal casing and metal valve housing (barrel) make for a rugged second stage able to withstand years of aggressive diving.
• Carbon fiber is extremely lightweight and, unlike metal that can change shape when dropped or struck against a hard object, carbon fiber can resist substantial shocks without damage.
• Metal case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
• DLC Black Tech coating protects from corrosion and scratches and lends a technical look to the regulator.
• Air balanced second stage smoothes out the inhalation effort when diving at varying depths and supply pressures.
• User controls include a diver-adjustable inhalation effort knob and coaxial Venturi-Initiated Vacuum Assist (VIVA) switch.
• Air balanced piston first stage in a Black Tech-coated brass body delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.
• With its patented ultra-freeze-resistant Extended Thermal Insulating System (XTIS) the MK25 EVO offers excellent thermal insulation by fully isolating the mechanical elements of the first stage from the cold, all without compromising breathing performance.
• Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
• Two opposing high pressure ports allow the first stage to be positioned either up or down.
• Four high-flow and one axial super 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.

Features S270 Octopus:

• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures
• Lightweight casing, made of a fiberglass-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 extreme cold water
• Dive/predive switch prevents freeflows when not being used
• Compact and efficient exhaust tee minimises exhalation effort
• 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
• 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.
