The MK25AF X650 is the latest high performance regulator in the SCUBAPRO regulator range. Based on the unique D400 pedigree, the X650 utilises similar internal components and high performance characteristics of the very popular Scubapro S600. This results in superlative performance, easy maintenance and incredible reliability. MK25 First Stage An unfailing performance, due to patented design The MK25 first stage can accept all types of SCUBAPRO second stages, and will be your favorite for all diving experiences. Machined marine grade chrome plated brass body Excellent resistance to corrosion, long lasting, and excellent value for its price. Patented over balanced composite/stainless steel piston Faster dynamic response and extra high flow, ultra stable intermediate pressure at all tank pressure. Thermal Insulating System (TIS) on piston and spring Cold water resistant. Exceeds CE cold water diving requirements. Externally adjustable intermediate pressure (patent pending) Easy and fast adjustment by authorized technician. 5 High flow low pressure swivel ports Ergonomic distribution of the hoses for less jaw fatigue and full option for octopus and accessories. Dual high pressure ports Console or pressure gauge can be mounted either right or left hand. Available in 232 bar yoke or DIN system Versatile use depending on geographical region. New wound conical single stainless steel wire filter Improved flow characteristics for absolute safety will prevent clogged filters from exploding. Enlarged water balancing chamber holes For cold water diving, improves heat transfer and increases resistance to freezing. Exceeds CE cold water norms at 300 bars. X650 Second Stage Based on the renowned D400, this one of a kind second stage includes a unique valve design. With new break through design and components, this extraordinary second stage offers the best performance on the market. Straight coaxial flow valve The air flow goes directly into the mouth to prevent any loss in performance. New smaller poppet With quicker dynamic response to inhalation demand. Diaphragm and exhaust valve positioned below the mouthpiece This structure, in combination with a streamlined shape and lighter weight minimizes jaw fatigue. New 15% wider exhaust valve 20% less exhalation effort than the other second stages. Dive/pre-dive control switch To prevent accidental free flow. New diver adjustable inhalation control To quickly increase or decrease the inhalation effort and fine-tune the second stage to any diving condition including cold water. A unique design with asymmetrical ribs to prevent excessive unscrewing and to have the clear perception of “zero” point. Lightweight orthodontically designed mouthpiece Comfortable, reducing jaw fatigue and gum irritation.
