Scubapro MK25 EVOG260 Black Tech R105 Octo

Scubapro MK25 EVOG260 Black Tech R105 Octo Scuba diving regulator

RUGGED, ALL-ROUND REG SYSTEM

Technical divers will love the solid breathing performance and proven reliability of this noted reg combo.

No doubt about it, the MK25 EVO/G260 BLACK TECH is a serious reg system designed for the most demanding divers. The air-balanced flow-through piston-style MK25 EVO BLACK TECH is consistently ranked as the top-performing first stage on the market. Its patented Extended Thermal Insulating System (XTIS) 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. Add the fins on the machined body that provide extra thermal exchange and you have the ultimate first stage for all water temperatures.

With the G260 BLACK TECH SCUBAPRO engineers have taken the most imitated air balanced second stage design of all time and offered it with a rugged, nylon fiberglass casing with freeze-resistant components and fitted with a dark anodized aluminum ring. Inside you have metal components (inlet tube, orifice, inhalation control knob and hose connector) to ensure excellent cold-water performance. It also offers a left-right hose attachment option, making it a great choice for tech diving configurations.

Both first and second stages have a BLACK TECH scratch-resistant coating that protects against the ravages of salt water and corrosion. This durable coating includes an inner layer of chemical Nickel (FDA approved) and an outer glossy DLC (Diamond Like Carbon) finish. It's a rugged reg system that delivers solid breathing performance in all diving conditions and water temperatures. It's a serious balanced piston breathing system that's as tough as it looks.  You can count on this outstanding reg to deliver top-of-the-line performance in all diving conditions and water temperatures, no matter how hard you're breathing, how deep you're diving, or how cold the water gets

Technical Information

MK25 EVO BLACK TECH First Stage:

• 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) 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.
• New spring insulating coating, body insulating bushing (non-metal cylindrical interface separating metal parts from water), anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance (key insulation system components are visible in blue).
• 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.
• Available in a 3364psi/232bar INT configuration.
• Weight: INT 232 (oz/g): 27.9/790.
• Airflow at 2900psi/200bar: (l/min/ SCFM): >8500/301.
• Intermediate pressure (psi/bar): 133-142/9.2-9.8.

G260 BLACK TECH Second Stage:

• Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
• Nylon fiberglass design features SCUBAPRO's biggest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
• Dark anodized aluminum front cover ring adds scratch resistance without adding weight.
• Metal components, including metal air barrel and metal valve inlet tube, increase resistance to freezing when diving in extreme conditions.
• High-flow exhaust valve reduces exhalation for better overall breathing comfort.
• A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes.
• Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch pre- vents free flows in cold water or when used as an octopus.
• Reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
• 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): 9.5oz/268g.
• Airflow at 2900psi/200bar: 1800 l/min - 64 SCFM.
• Maximum low pressure: 203psi/14bar.

R105 Octopus:

• Classic downstream valve design for dependable breathing performance
• Metal valve housing is built rugged and increases overall reliability.
• Reversible hose attachment makes it easy to use on pony or deco tanks.
• High-viz yellow super-flow hose is 39in/1m long and features an oversized bore that allows more air to flow on each inhalation.
• Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest.
