Scubapro MK25 EVO/S600 Regulator Stage 3 Set

*Stage 3 sets come with 1st stage, 2nd stage and octo*

The MK25 EVO first stage lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and impressive airflow. The S600 delivers smooth and easy inhalation and exhalation while offering efficient user controls, including a powerful purge, an inhalation effort control knob and Venturi Initiated Vacuum Assist (VIVA). Together they provide a steady flow of air, regardless of depth, water temperature, or workload.

The set includes a highly reliable R195 octopus with an extra-long visibility hose and reversible hose attachment.

MK25 EVO/S600

• Air balanced flow-through piston in a chrome plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Patented XTIS (Extended thermal Insulating system) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions 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.
• Air balanced second stage valve smoothes out the inhalation effort at varying depths and supply pressures.
• Second stage’s rugged reinforced technopolymer case and front cover with stainless steel frame looks good plus is extremely durable.
• Metal valve housing (barrel) is able to withstand years of aggressive diving.
• User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.
• Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.

R105 Octo

• High visibility yellow cover makes it easy to see when it comes time to share air with a buddy in need.
• Rugged reinforced technopolymer casing is fitted with a large diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
• Classic downstream valve comes with a VIVA switch to control free flows.
• Metal valve housing is built rugged and increases overall reliability.
• Yellow super-flow hose is 39in/1m long and features an oversized bore that allows more air to flow on each inhalation.
• Reversible hose attachment makes it easy to use on deco tanks.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
