The Cressi AC25M MASTER CROMO brings a modern twist to the traditional piston-style regulator. Particularly popular in North and Latin America, the AC25M 1st stage is designed for use in water temperatures of 10°C and above. Its 360° rotating turret allows for flexible hose routing and lets the regulator hose move with you as you look around underwater. An additional 5th co-axial Hi-Flow MP port on top of the turret provides plenty of configuration options, making it an excellent choice for sidemount divers. Unique to Cressi is the AC25M’s external Intermediate Pressure (IP) adjustment system, which allows service centres to fine-tune the IP while the 1st stage is attached to the cylinder. Also unique to Cressi is the high-capacity conical filter, which offers a larger surface area than traditional flat filters, trapping more cylinder impurities for cleaner air. The MASTER CROMO 2nd stage complements the AC25M perfectly with its pneumatically balanced design. Its patented elliptical diaphragm has an increased surface area, reducing inhalation effort for a more comfortable breathing experience. Divers can fine-tune airflow with the inhalation effort adjuster, while the adjustable Venturi system minimises free-flows. For cold-water reliability, the internal heat exchanger reduces the risk of the 2nd stage freezing. The MASTER CROMO features our Safe-Flex hose, which is incredibly flexible compared with traditional hoses.
