Scubapro D420 Second Stage features
The Scubapro D420 Second Stage Regulator combines the original D-Series regulators’ classic design with the latest breathing performance technology advances. Scubapro engineers have created a 21st-century smooth natural breathing regulator.
D420 can deliver abundant airflow for the best breathing performance with a natural smoothness comparable to what you might experience breathing on the surface.
The Scubapro D420 second stage, with its chrome-plated marine-grade brass body, features a brand new balanced valve inside a housing supported by a full metal structure.
The Progressive Flow Control Valve can 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 fibreglass-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 to adjust the airflow direction 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. The Scubapro D420 Second Stage Regulator’s long list of features, including nitrox compatibility of up to 40%, is sure to enhance any diver’s underwater experience.
- Nitrox compatible to 40%
- Weight (without mouthpiece) 216g
- Airflow at 200bar: 1800 l/min - 64 SCFM
Scubapro MK25 EVO First Stage features
Scubapro MK25 EVO First Stage Regulator lets you enjoy an ultra-fast breathing response, instant air delivery on demand, great sensitivity and extra-high airflow - regardless of the water’s cold.
Air-balanced flow-through piston design provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
MK25 EVO is cold water rated
Patented XTIS (Extended Thermal Insulating System) fully insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold-water conditions without compromising breathing performance.
Anti-freeze protection radically increases breathing reliability when diving in extreme water temperatures.
Scubapro MK25 EVO First Stage Regulator is CE certified according to the latest EN250A European Standards for all diving conditions, including extreme cold water.
Excellent hose routing
Two high-pressure and five high-flow low-pressure ports on a swivel turret maximise hose routing options.
External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
- Nitrox compatible to 40%
- 300bar DIN connection
- Weight: 572g
- Airflow at 2900psi (l/min/SCFM): >8500/301
- Intermediate pressure 9-9.8bar
- 2 High Pressure Ports
- 5 Low Pressure Ports
- Chrome-plated brass
DIN or A-clamp first stage?
Most of our divers prefer DIN fitting on the 1st stage regulator. A DIN regulator has a threaded post which screws into the inside of a DIN tank valve and has no additional metal or braces that run behind the valve. This, together with the position of its o-ring, creates a more secure seal on the tank.
YOKE (or A-Clamp) 1st stages have an oblong metal brace that completely encircles the tank valve when in place and is screwed down on the tank valve when the yoke screw is tightened.
Both regulators seal to the scuba tank through an o-ring where the o-ring on a Yoke valve is in the tank valve itself as opposed to DIN regulators with their own o-ring.
DIN fittings are commonly accepted as more secure, but Yoke valves are common throughout North America and recreational tourist destinations. A DIN regulator can be adapted to Yoke valves by using an A-clamp adapter for travel.
