The Scubapro Regulator MK25 EVO / D420 with the Octopus R195
With this very performant regulator combination of the MK25 EVO 1st stage, with the new D420 2nd stage, also available in the MK19EVO D420 Regulator System with diaphragm-controlled 1st stage, and the R195 octopus, Scubapro has created an absolute high-end regulator, also availabe in our online shop for dive gear as a complete system MK25EVO D420 R195 inluding inflator hose, pressure gauge and regulator bag, a professional regulator with new design and significantly improved breathing performance, perfectly suitable for Deep divers, professional divers or diving instructors.
The Scubapro 1st stage MK25 EVO
The MK25 EVO is a very robust, balanced, piston-controlled 1st stage that provides you with a constantly good airflow at any depth, at any breathing rate and even at low tank pressure, thanks to the innovative air-balanced flow piston.
Freezing resistant 1st stage thanks to innovative technology
The new MK25 EVO is equipped with the revolutionary XTIS technology, the Extended Thermal Insulating System technology, with which Scubapro opens a new era in cold water protection technology. Thanks to this technology, this first stage has CE certification according to the latest European standard EN 250A for all diving conditions, even for use in very cold water. The MK25 EVO has up to 30% better cold water resistance than all previous models - ice diving, deep diving, technical diving - with the new Scubapro EVO 1.stages this is no longer a problem. Because the mechanical components of the Scubapro EVO 1.stages are completely insulated thanks to the new XTIS technology, and the additional fins increase the heat exchange in cold water. In addition, an anti-frost cap provides even more thermal insulation.
Sophisticated design for variable configurations
The 2 high-pressure ports of the MK25 EVO are placed on both sides, which allows variable mounting of the 1st stage (facing up or down). This stage offers no less than five LP ports, which are placed on a 360° rotatable swivel head to allow you absolute creative freedom in assemblying your hose configuration. One of the 5 ports is a high-performance, axial ND outlet.
Many practical features
But this Scubapro 1st stage has much more to offer, such as a replaceable valve seat or externally adjustable intermediate pressure.
The 2nd stage Scubapro D420
The Scubapro D420 2nd stage is a brand new 2nd stage that impresses with its innovative design and revolutionary features.
Improved breathing comfort through design innovation
Even at first glance, the D420 raises questions, as its design deviates from the known standards. However, these design changes are not just meant to look good, they're design innovations that significantly improve the breathing comfort.
For example, the exhaust valve 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.
With practical Dive / Pre-Dive switch
On top of the 2nd stage is a dive / pre-dive thumb switch that allows you to adjust the direction of the air flow.
Increased inhalation comfort and improved exhalation effort
Inside the innovative nylon housing of the D420 air deflectors were installed in order to direct the air to the exhaust valve to significantly reduce the exhalation effort.
What you don’t see, but clearly recognizable when diving with the Scubapro D420, is the incredibly high breathing comfort that is comparable to breathing free at the water surface, and this is due to the air-balanced control valve inside the D420 that delivers a progressive airflow.
Superflow hose with high air flow
Also, the "Superflow" hose of the D420, ensures high airflow,resulting in excellent breathing performance.
This Scubapro 2nd stage is easy to assemble and disassemble, and can be mounted on the right or left side of the hose.
Absolutely freezing resistant
Just try it – you will notice soon that you have barely ever breathed more comfortable than with this second stage, no matter how deep or how cold, because, like most Scubapro second stages, the D420 has excellent cold-water Features.
The Scubapro Octopus R195
Compact Octopus with pleasant breathing comfort
The alternative air supply Scubapro R195 is very light and compact and is equipped with a classic downstream valve that guarantees safe and reliable operation. The R195 is not only popular for its comfortable breathing, but also for its compact size and light weight, as it is made from a very durable yet very light plastic.
Fits any Scubapro regulator
This Scubapro Octopus can of course be fitted to any Scubapro 1 stage, and the medium pressure hose can be fitted to either side of the R195.
Comfortable and practical alternate air supply
The mouthpiece of the R195 ensures relaxed neck and jaw muscles even during Long dives or in strong currents thanks to the very comfortable orthodontic shape developed together with dentists and dental laboratories.
Equipped with the luxury of an adjustable VIVA lever and an easy-to-operate purge button, with a constant, comfortable air delivery, the R195 is a reliable air supply for emergency diving situations.
In our online dive shop you will find many more Scubapro 1st stages and Scubapro 2nd stages to upgrade this regulator, for example to a cold water configuration.
