MK25 Evo First Stage

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.

Introducing the new D420 regulator

Scubapro's D420 regulator, inspired by the iconic D-Series, combines classic design with the latest breathing performance technology. It offers quality, reliability, and style for today's discerning divers. The new D420 features a balanced valve called the Progressive Flow Control Valve, delivering abundant airflow and a natural, smooth breathing experience similar to being on the surface. Its durable fiberglass-reinforced nylon casing allows flexible rigging with LP hose connections on either side.

Paired with the MK25 EVO balanced piston first stage, the D420 offers exceptional performance for avid divers. The MK25 EVO provides ultra-stable intermediate pressure, ensuring a consistent, high air delivery regardless of tank pressure or water temperature. Its balanced piston design delivers more air to the second stage and performs equally well in both warm and cold-water environments.

The MK25 EVO features two high-pressure ports, five high-flow low-pressure ports, and an externally adjustable intermediate pressure for fine-tuning by Scubapro technicians. Its new Extended Thermal Insulating System (XTIS) increases freezing resistance by 30%, making it suitable for cold-water diving, tested in extreme conditions below 36 Degree F (2.2 Degree C).

The D420 second stage regulator's unique casing design improves exhalation effort, and its diaphragm takes advantage of pressure gradients for easier breathing. Its reversible hose attachment, large purge button, and compact exhaust tee enhance user experience. The regulator weighs 40.8 oz. (1,157 g), is Nitrox compatible up to 40% oxygen, and includes an owner's manual.

Experience the perfect blend of tradition and innovation with Scubapro's D420 and MK25 EVO regulator system, designed to meet the needs of modern divers while staying true to the brand's heritage.
