SCUBAPRO MK19 EVO D420 Regulator Set

With The Introduction Of The D420, Scubapro Engineers Have Combined The Iconic Design Of The Original D-Series Second Stages With The Latest Advances In Breathing Performance Technology. They Then Teamed It With The Mk19 Evo Balanced Diaphragm First Stage To Create A 21st Century Smooth, Natural Breathing Regulator. The D420 Features A 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 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 Concept That Gives The D420 Its Unique Face. Teamed With The Compact, Lightweight Mk19 Evo, With Its Environmentally Sealed System, Dry Ambient Pressure Chamber Plus User-Friendly Lp Port Swivel Turret, This Regulator System Is Uniquely Well-Suited To Handling Cold Water And The Harsh Diving Conditions Often Encountered By Technical Divers. This Makes The Mk19 Evo/D420 More Tech-Driven Than The Mk25 Evo/D420, While Serving Avid Divers And Scubapro Brand Enthusiasts Everywhere.
