Scubapro MK25 EVO DIN 300/G260 Regulator - REG364 DIN

When you team SCUBAPRO's flagship first stage with a second stage engineered to excel in harsh conditions, you get a system that any recreational or technical diver can take on any dive, anywhere in the world, and be assured of rock-solid performance and reliability. The MK25 EVO/G260 is just such a system. The MK25 EVO delivers an ultra-fast breathing response, great sensitivity and extra-high airflow, making it the ultimate do-it-all first stage for all water temperatures. The G260 is the most imitated air-balanced second stage of all time. It features metal internal components and a left-right hose attachment option, making it a great choice for tech diving configurations and a consistent top-of-the-line performer.

Features
  • 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) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing 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.
  • Four high-flow and one axial super 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.
  • Air-balanced second stage valve smooths out the inhalation effort at varying depths and supply pressures.
  • Rugged reinforced technopolymer design features SCUBAPRO's largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
  • Metal components (inlet tube, orifice, inhalation control knob and hose connector) increase resistance to freezing when diving in extreme conditions.
  • A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes, and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
What our Experts Think
  • Top-tier breathing performance: The Scubapro MK25 EVO DIN 300/G260 Regulator pairs Scubapro's flagship air-balanced piston first stage with the high-performance G260 second stage for exceptionally smooth airflow at any depth.
  • Excellent cold-water reliability: The patented XTIS (Extended Thermal Insulating System) and advanced anti-freeze protection help maintain consistent breathing performance in demanding cold-water conditions.
  • Precision diver adjustment: The G260 second stage features an adjustable inhalation effort knob and VIVA (Venturi-Initiated Vacuum Assist) control, allowing divers to fine-tune breathing resistance and reduce free-flow.
  • Ideal for technical diving: A reversible left/right hose attachment, swivel turret with five high-flow LP ports, and two HP ports provide outstanding hose routing flexibility for recreational and technical configurations.
  • Built for extreme durability: Metal internal components, reinforced technopolymer construction, and a high-flow exhaust valve deliver long-lasting reliability and effortless exhalation in harsh environments.
  • Professional-grade investment: Combining industry-leading airflow, rugged construction, and all-condition performance, this regulator system is an outstanding choice for serious recreational, technical, and cold-water divers.

Q&A

Q: What type of diving is the Scubapro MK25 EVO/G260 regulator designed for?
A: It is designed for recreational, technical, cold-water, and deep diving, delivering exceptional breathing performance in demanding conditions.

Q: What makes the MK25 EVO first stage unique?
A: The balanced piston first stage provides outstanding airflow and consistent breathing performance, even at low tank pressures and in cold water.

Q: What are the benefits of the G260 second stage?
A: The balanced adjustable G260 second stage offers smooth, effortless breathing with user-adjustable inhalation resistance and Venturi control.

Q: What does the DIN 300 connection mean?
A: The DIN 300 fitting is a high-pressure threaded connection rated for up to 300 bar (4,350 psi), providing a secure and reliable attachment to compatible cylinders.

Q: Is this regulator suitable for cold-water diving?
A: Yes. The MK25 EVO features Extended Thermal Insulating System (XTIS) technology to improve freeze resistance, making it an excellent choice for cold-water environments.

Q: Does the regulator require regular servicing?
A: Yes. Like all scuba regulators, it should be inspected and serviced regularly by an authorized Scubapro technician to ensure optimal safety and performance.


Maintenance Tips
  • Rinse the regulator thoroughly with fresh water after every dive, preferably while it is still pressurized. If unpressurized, ensure the dust cap is securely fitted before rinsing.
  • Allow all components to air dry completely in a cool, shaded area before storage to help prevent corrosion and moisture buildup.
  • Inspect the DIN connection, hoses, O-rings, mouthpiece, and fittings before each dive for wear, cracks, corrosion, or leaks.
  • Keep the first-stage dust cap clean and securely in place whenever the regulator is disconnected from the cylinder to prevent water and debris from entering.
  • Operate the Venturi (VIVA) and inhalation adjustment controls periodically to ensure smooth movement, but avoid making internal adjustments beyond user controls.
  • Store the regulator loosely coiled in a padded regulator bag away from direct sunlight, extreme temperatures, and heavy objects that could damage hoses.
  • Have the regulator inspected annually and professionally serviced at the manufacturer's recommended intervals by an authorized SCUBAPRO technician to maintain safe, reliable performance.
