MK25 Evo/D420 Dive Regulator System
MK25 Evo/D420 Dive Regulator System, Combining the iconic design of the original D-Series regulators with the latest advances in breathing performance technology, SCUBAPRO engineers have created a 21st century regulator in terms of quality, reliability, performance and style. The new D420 features a brand new balanced valve inside a housing supported by a full metal structure. Called the Progressive Flow Control Valve, it is able to deliver abundant airflow for the best breathing performance, with a natural smoothness comparable to what you might experience breathing on the surface. The uniquely shaped fiberglass-reinforced nylon casing is ultra-durable and allows the LP hose to be connected on either the right or left side for maximum rigging flexibility. A new dive/pre-dive system includes a switch on the top of the casing with a thumb tab for adjusting the direction of airflow right out of the valve. The highly efficient purge button is a technical jewel based on a new concept that gives the D420 its unique face. Teamed with the venerable MK25 EVO balanced piston first stage, this is a regulator system purpose-designed for today's avid divers and SCUBAPRO brand enthusiasts everywhere. 2nd Stage Design Balanced | 1st Stage Type Piston | Water Temperature Cold, Temperate, Warm | Connector Type INT | Nitrox Mix Up to 40% | HP Ports 2 | LP Ports 5 | 1st Stage Materials Chrome-Plated Brass | 2nd Stage Materials Reinforced Technopolymer Casing, Metal Components | Product Weight 2.6 lb | Adjustable 2nd Stage No | 2nd Stage Valve Housing Material Technopolymer | UPC 4048336404297.
