ScubaPro MK25/G260 Tactical Balanced Regulator

The Sealteam 6 of reg systems.

Aimed at technical divers, this bullet-proof breather can face any dive situation with rock-solid performance and outstanding reliability. No doubt about it, the MK25 EVO/G260 TACTICAL is a serious reg system designed for the most demanding divers. The air-balanced flow-through piston-style MK25 has consistently ranked as the top-performing first stage on the market.  And now it's even better. With the introduction of the new patent-pending Extended Thermal Insulating System (XTIS), the MK25 EVO now 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.

The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over the current MK25 without compromising breathing performance. Plus, fins on the machined body provide extra thermal exchange. Put it all together and you have the ultimate first stage for all water temperatures.
With the G260 TACTICAL SCUBAPRO engineers have taken the most imitated air balanced second stage design of all time and offered it with a rugged, nylon fiberglass casing fitted with a dark anodized aluminum ring.

Then they added a stealthy design to the inhalation effort control knob, and topped it off with a new hose swivel that decreases jaw fatigue and enhances overall comfort and range of motion. The G260 TACTICAL is built with 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.
The MK25 EVO/G260 TACTICAL is 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, no matter how hard you're breathing, how deep you're diving, or how cold the water gets.


  • Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
  • Patent-pending XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the current MK25 without compromising 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 high pressure and 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 either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
  • Weight: INT 232 (oz/g): 29.1/825; DIN 300 (oz/g): 20.9/592.
  • Airflow at 2900psi (l/min/SCFM): >8500/301.
  • Intermediate pressure (psi/bar): 130-142/9-9.8.


  • Casing is built from rugged nylon fiberglass and fitted with a dark anodized aluminum ring to stand up to aggressive diving.
  • New second stage hose swivel with flexible cover enhances range of motion, comfort and control.
  • Metal components provide increased resistance to freezing when diving in extreme water conditions.
  • Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
  • High-flow exhaust valve reduces exhalation for better overall breathing comfort.
  • A stealth-designed 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 prevents 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 (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.
