STELLAR BREATHING PERFORMANCE, OUTSTANDING RELIABILITY

 

The ultimate go-to air delivery system for cold water or technical diving.

 

 

When you team SCUBAPRO's flagship first stage with an air-balanced second stage engineered to excel in harsh, cold-water conditions, what you get is a regulator system that any hard-core recreational or technical diver can confidently take on any dive, anywhere in the world, and be assured of rock-solid performance and outstanding reliability. In other words, the MK25 EVO/G260.

 

The MK25 EVO first stage lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow -- regardless of how cold the water is. This is made possible with SCUBAPRO's exclusive patent-pending Extended Thermal Insulating System (XTIS) that fully isolates the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over previous versions of the MK25 without compromising breathing performance. This makes the MK25 EVO the ultimate do-it-all first stage for all water temperatures.

 

The G260 is the most imitated air balanced second stage design of all time. First introduced in 1986 as the G250, it was the first regulator to introduce an adjustable Venturi Initiated Vacuum Assist (VIVA). Today's modern version features metal components (inlet tube, orifice, inhalation control knob and hose connector) for excellent cold-water performance. It also offers a left-right hose attachment option, making it a great choice for tech diving configurations.

Of course, you don't need to dive in cold water or find yourself in extreme diving conditions to fully appreciate the powerful yet easy-breathing attributes of this reg system. But if you're a demanding diver you can rest assured that with every breath you take, the MK25 EVO/G260 will deliver effortless airflow and consistent top-of-the-line performance.

RACE CAR SLEEK, BATTLE TANK TOUGH

It's Diving's Ultimate Reg System

The premium high-performance 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 and the toughest in terms of high-tech durability.

Like the original A700, the A700 CARBON's casing is full metal to take advantage of the extremely high heat exchange rate that makes this second stage such a great choice for cold-water diving. However, the screw-down front cover, in place of metal, is hand-made out of carbon fiber - the same material you find on aircraft and high-speed race cars. 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.

Performance-wise, the A700 CARBON retains the same muscular performance as the all-metal A700. Its air-balanced valve technology and oversized exhaust valve work in conjunction with a well designed sectional exhaust tee, a first-rate purge and responsive user controls to create a tech-tough breather with effortless inhalation and an ease of exhalation that is unmatched. It's now just lighter and tougher.

The A700 CARBON is teamed with the MK25 EVO, widely considered the gold standard in first stage performance. This air-balanced flow-through piston design delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate. With its 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.

Finishing off this premium air delivery system is a DLC (Diamond-Like Carbon) BLACK TECH coating that's applied to both first and second stages. This unique coating not only lends a sleek technical look to the system, its scratch- and corrosion-resistant properties perform an important function in protecting the reg against the strains and stresses of technical diving as well as the ravages of the saltwater environment.

Put it all together and you have the MK25 EVO/A700 CARBON BLACK TECH, diving's ultimate muscle reg, built with high-tech materials and sporting race-car-sleek styling. It looks great, is ultra-durable, and delivers the best breathing performance around.
