The premium MK25 EVO/Carbon Black Tech is not only the best-breathing reg in Scubapro’s line, it’s also the leader in advanced design and materials. The A700 Carbon’s main casing is full metal to take advantage of the extremely high heat exchange rate that makes it such a great choice for cold-water diving, and its front cover is handmade out of lightweight and durable carbon fiber. The A700 Carbon is teamed with the MK25 EVO, widely considered the gold standard in first stage performance, and finishing off this premium air delivery system is a DLC (Diamond-Like Carbon) Black Tech coating. Put it all together and you have diving’s ultimate muscle reg that looks great, is ultra-durable, and delivers the best breathing performance around.

First Stage:

• Air balanced flow-through piston in a Black Tech-coated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Patent pending XTIS (Extended thermal Insulating system) fully insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold-water conditions without com- promising breathing performance. Key insulation system components are visible in blue.
• New spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water 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.
• Five high-flow low pressure ports on a swivel turret maximize hose routing options.

Second Stage:

• Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
• Hand-made carbon fiber front cover and rugged metal case and valve housing are able to withstand years of aggressive diving.
• Metal case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
• User controls include a diver-adjustable inhalation effort knob and coaxial-flow Venturi-Initiated Vacuum Assist (VIVA) lever.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.
