The Scubapro MK25 EVO A700 Carbon Black Tech + S270 Octopus regulator set includes MK25 EVO A700 Carbon BT regulator which is not only the best-breathing reg in Scubapro’s line but also the leader in advanced design and materials. The set is complemented with an air-balanced Scubapro S270 Octopus that smoothes out the inhalation effort when diving at varying depths and supply pressures.
Scubapro MK25 EVO A700 Carbon Black Tech is a race car sleek, battle tank tough
Like the original A700 second stage, the A700 Carbon's casing is full metal to take advantage of the extremely high heat exchange rate, making this second stage 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 which 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 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 applied to the 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 and the ravages of the saltwater environment.
Put it all together, and you have the Scubapro MK25 EVO A700 Carbon Black Tech Regulator, 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.
MK25 EVO A700 Carbon Black Tech + S270 Octopus set includes
- Scubapro A700 Carbon Black Tech second stage
- Scubapro MK25 EVO Carbon Black Tech second stage
- Scubapro S270 Octopus
- Scubapro High-flow regulator hose
- Scubapro High-flow yellow octopus hose
A700 Carbon Black Tech 2nd stage
Hand-made 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 virtually bulletproof and also extremely lightweight. The A700 Carbon's cover weighs only 10 grams, compared to the 42-gram weight of the original A700's metal cover, resulting in more comfortable diving.
DLC Black Tech coating protects from corrosion and scratches and lends a technical look to the regulator.
Special Torx cover screws are able to support a higher tightening torque without damage.
Metal case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
Air-balancing 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.
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.
- Weight (without mouthpiece): 8.0oz/228g
- Airflow at 2900psi/200bar: 2000 l/ min - 71 SCFM
MK25 EVO Carbon Black Tech 1st 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.
DLC Black Tech coating protects from corrosion and scratches and lends a technical look to the regulator.
Patented 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 compromising 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.
External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
DIN version comes with a new dual-compound wheel that features a new ergo shape and soft grip on a rugged black nylon frame.- Weight: INT 232 790g; DIN 300 570g
- Airflow at 2900psi/200bar: (l/min/ SCFM): >8500/301
- Intermediate pressure (psi/bar): 133-142/9.2-9.8
Scubapro A270 Octopus
The ideal backup breather for your dive system, the Scubapro S270 Octopus is tough, reliable, and easy to use. Its air-balanced design can be counted on to deliver top-notch breathing performance when needed.
Air-balanced Scubapro S270 Octopus 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.
The compact Hi-Flow mouthpiece is comfortable, made with FDA-approved silicone and features a large cross-section to maximize airflow.
High-viz yellow super-flow hose is 1m long with an oversized bore allowing more air flow on each inhalation.
- Dive/predive switch prevents freeflows when not being used
- Compact and efficient exhaust tee minimizes exhalation effort
- High-viz yellow front cover stands out, making it easy to spot when needed
DIN or A-clamp first stage?
Most of our divers prefer DIN fitting on the 1st stage regulator. A DIN regulator has a threaded post which screws into the inside of a DIN tank valve and has no additional metal or braces that run behind the valve. This, together with the position of its o-ring, creates a more secure seal on the tank.
YOKE (or A-Clamp) 1st stages have an oblong metal brace that completely encircles the tank valve when in place and is screwed down on the tank valve when the yoke screw is tightened.
Both regulators seal to the scuba tank through an o-ring where the o-ring on a Yoke valve is in the tank valve itself as opposed to DIN regulators with their own o-ring.
DIN fittings are commonly accepted as more secure, but Yoke valves are common throughout North America and recreational tourist destinations. A DIN regulator can be adapted to Yoke valves by using an A-clamp adapter for travel.
