Scubapro MK 25T Evo / S620 X-TI INT Dive Regulator System

SCUBAPRO MK25T EVO / S620 X-TI INT Dive Regulator System combines advanced regulator technology with an ultralight titanium design for scuba diving. The MK25T EVO is machined from a solid block of titanium, delivering exceptional corrosion resistance in saltwater and years of trouble-free use. The S620 X-Ti builds on the renowned S600 platform, offering effortless airflow in a smaller, lighter package, with a titanium inlet tube, a large purge button, and an improved exhaust tee to enhance performance.

In underwater gear terms, this regulator system emphasizes cold-water reliability and smooth breathing. The XTIS Extended Thermal Insulating System thermally insulates the inner mechanism to improve cold-water resistance and delay ice formation without compromising breathing performance. It supports Nitrox up to 40% and pairs a rugged titanium construction with thoughtful design details that support diving comfort and visibility.

• Machined titanium body is lightweight, highly resistant to corrosion, and ultra-durable.
• Air-balanced flow-through piston provides effortless airflow unaffected by depth, tank pressure, or breathing rate.
• XTIS (Extended Thermal Insulating System) thermally insulates the inner mechanism for better cold-water performance.
• Two opposing high-pressure ports allow the first stage to be positioned up or down; five low-pressure ports enable versatile hose routing.
• External intermediate pressure adjustment enables quick, precise tuning by technicians or divers.
• Air-balanced valve smoothes inhalation effort across varying depths and supply pressures.
• Full titanium barrel provides rugged, anti-corrosion durability with low weight.
• Large diaphragm in a compact casing supports maximum breathing sensitivity.
• Easy-grip diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) lever for user control.
• Exhaust tee directs bubbles out of the field of view to maintain visibility during dives.
• Designed compact Hi-Flow mouthpiece mounted on an enlarged mouthpiece pipe for improved airflow and mouth comfort.
• Nitrox compatibility up to 40% for enriched air diving.
• INT connector type for compatibility with standard regulator setups.
• 1st Stage Materials: Titanium; 2nd Stage Materials: Titanium components.
• Weight: 1.9 lb (overall system).
• 1st Stage Type: Piston; 2nd Stage Design: Balanced; 2nd Stage Series: S Series.
• Water Temperature range: Cold, Temperate, Warm.
