Scubapro MK25 EVOBT/S620Ti 60th Anniversary Carbon BT

SCUBAPRO marks its 60th anniversary with the MK25 EVO/S620Ti Carbon BT, a limited-edition regulator designed for scuba and diving gear. The piston-first stage uses a chrome-plated brass body with a durable Black Tech DLC coating, paired with a titanium-based second stage for reliable underwater breathing in a variety of conditions. This carbon edition emphasizes durability and performance for serious divers in aquatic environments.

The regulator delivers consistent airflow through an air-balanced flow-through piston design, ensuring breathing comfort at depth and across tank pressures. The XTIS Extended Thermal Insulating System fully insulates the internal mechanism to improve cold-water performance, and anti-freeze protection further enhances reliability in extreme water temperatures. Two opposing high-pressure ports allow flexible orientation, while a swivel turret on the low-pressure side provides routing options with four high-flow and one axial super high-flow LP ports.

Breathing control is supported by an air-balanced valve and a compact diaphragm to maximize sensitivity, with user controls including an easy-grip diver-adjustable inhalation effort knob and a Venturi-Initiated Vacuum Assist (VIVA) lever. The exhaust tee keeps bubbles out of the field of view for better underwater visibility, and the Hi-Flow mouthpiece on an enlarged mouthpiece pipe improves airflow and mouth comfort. A super-flow hose with an oversized bore enhances air delivery per inhalation. The first stage is piston-driven and the second stage uses the S Series with titanium components and a titanium valve housing, delivering robust performance in warm, cold, or temperate water.
