The Scubapro regulator MK19 EVO / D420
This powerful Scubapro regulator consists of the MK19 EVO 1st stage and the brand-new Scubapro D420 2nd stage, which you can find in our online shop for diving equipment in combination with the piston-controlled 1st stage MK25 EVO as a Scubapro MK25 EVO D420 regulator. The Scubapro MK19 EVO D420 regulator is an absolute high end regulator, with a modern design and excellent breathing performance, a professional regulator for demanding divers or a diving instructor Regulator.
The Scubapro 1st stage MK19 EVO
The Scubapro MK19 EVO 1st stage is an balanced, membrane-controlled high-performance stage, which is perfectly armed against very low temperatures with special cold-water technology. The 1st stage MK19 EVO uses the patented AF anti-freeze protection, which is created by attaching a series of fins to the chrome-plated brass housing of the 1st stages, the surface of which acts as a heat dissipater. This means that the MK19 EVO does not freeze up, even in very cold water.
In addition, the Scubapro MK19 EVO is equipped with a dry balance chamber that prevents water from entering the balance chamber, and thus preventing ice crystals from forming around the main spring, even in extremely cold water conditions.
Like the MK17 EVO, the Scubapro MK19 EVO also scores with significantly improved air delivery performance thanks to the optimized internal design, which ensures a higher air flow to the medium pressure ports. Also a novelty are the 5 and not only 4 high-flow ports of the Scubapro MK19 EVO 1st stage, which are attached to a practical swivel turret.
The Scubapro MK19 EVO is a solid and compact 1st stage, with a cover that reminds of the MK17 EVO 1st stage and with a non-slip and robust handwheel in the DIN version.
The 2nd stage Scubapro D420
The Scubapro D420 2nd stage is a brand new Scubapro 2nd stage that impresses with its innovative design and revolutionary features.
Even at first glance, the Scubapro D420 2nd stage raises questions, as its design deviates from the known standards. However, these design changes of the Scubapro D420 are not just meant to look good, they're design innovations that significantly improve the breathing comfort.
For example, the exhaust valve of the Scubapro 2nd stage D420 is located in the lower part of the second stage, which means that the pressure gradient in an upright position is better used to improve breathing.
On top of the Scubapro 2nd stage D420 is a dive / pre-dive thumb switch that allows you to adjust the direction of the air flow.
Inside the innovative nylon housing of the Scubapro D420 2nd stage air deflectors were installed in order to direct the air to the exhaust valve to significantly reduce the exhalation resistance.
What you don’t see, but clearly recognizable when diving with the Scubapro D420 second stage, is the incredibly comfortable breathing resistance that is comparable to breathing at the water surface, as the D420 incorporates an air-balanced control valve that delivers a progressive airflow.
Also, the "Superflow" hose of the Scubapro second stage D420, ensures high airflow, and therefore excellent breathing performance-
Just try it – you will notice soon that you have barely ever breathed more comfortable than with the Scubapro D420 2nd stage no matter how deep or how cold, because, like most Scubapro second stages, the D420 2nd stage has excellent cold-water features.
The D420 Scubapro 2nd stage is easy to assemble and disassemble, and can be mounted on the right or left side of the hose.
