The Scubapro MK25 EVO S600 is a very high performance regulator that is designed for cold conditions. The MK25 first stage is paired with the S600 second stage for effortless breathe and excellent coldwater performance.
MK25 EVO 1st Stage is one of the highest highest performance first stages available now with a dramatically evolved balanced piston first stage with 30% increased freezing resistance, greater inhalation sensitivity for ultrafast breathing response, instant delivery of air on demand and extra high airflow no matter how cold the water temperature. The balanced piston design is more than capable of supporting a whole team of divers simultaneously without faltering. The sleek body has heat exchanging fins incorporated into it's design to aid dissipation of the cold generated by the first stage as it works. The piston and main spring have been specially coated with an anti-freeze layer to improve coldwater performance and reliability. The MK25 provides two high pressure ports and five low pressure ports (four around a swivelling turret and a high flow port of the very end of the turret).
Extended Thermal Insulating System, X-TIS, fully insulates the internal mechanism from the environment. A form of environmental seal the X-TIS improves cold water / freezing resistance without compromising piston breathing performance (patent pending).
The S600 Second Stage evolves into its 5th generation design, building on the exception performance with an improved look. The S600 ensures excellent air flow rates and low inhalation resistance to provide a very comfort breathe.
Balanced Downstream Valve gives the diver control over the inhalation resistance, allowing customisation by increasing the resistance and inhalation effort required to open the valve if required.
A Venturi Control provides a variable level of protection from free flows by changing the direction of air flow with the housing, directing towards the mouthpiece for optimal air flow and performance or back towards the diaphragm to help automatically shut the valve as quickly as possible.The compact size of the second stage helps to reduce overall drag and improves comfort during use by minimising the weight.

Scubapro MK25 Evo S600 Regulator - Features
?This feature allows the diver to adjust the inhalation setting from the set level and increase the effort required to open the 2nd stage valve to deliver air.
?The venturi control affects how air flows in the 2nd stage. In it's positive position the flow of gas creates a vacuum against the diapragm, helping to open the valve. In it's negative position it will divert gas back against the diaphragm helping to close the valve. It is basically used to help prevent free flowing.
|Cold Water Rated|
?Cold water has adverse effects on regulators and can cause some to freeze so each regulator combination must be tested during manufacturing for their performance in different water temperatures.
Cold water is defined by EN250 as below 10°C. If a regulator combination cannot meet the performance standards below 10°C then they are only suitable for warm waters.
EN250 / (EN250A >10°C)
To pass the regulator must provide at least 62.5 L/min of air at 50M depth above 10°C.
|Cold & Warm Water|
?Environmentally sealed 1st stages offer greater protection against freezing when diving in cold water (below 10 degrees C)
Scubapro have a new method of cold water proofing their first stages called the eXtended Thermal Insulating System or XTIS which still allows water into the first stage but the internal parts that come into contact with the water are coated to prevent ice from forming.
?Unbalanced regulators are affected by the pressure in the cylinder, becoming slighty harder to breathe from when the pressure starts to drop.
Balanced regulators are not affected by the cylinder pressure or depth.
Over-balanced regulators achieve unprecedented performance by increasing your air supply the deeper you go providing the best breathe for deep divers.
|High Pressure Ports|
?High pressure ports supply the pressure gauge and wireless transmitters for dive computers
|Low Pressure Ports|
?Low pressure ports supply the 2nd stages and inflator hoses
?An Unbalanced second stage is simply a lever operated valve that is opened and closed as the diaphragm is pulled inwards by the vacuum that is created when the diver inhales. An unbalanced second stage is affected by increased pressure at depth, slightly increasing the effort required to open the valve.
A Balanced second stage overcomes the effects of increased pressure by utilising a balancing chamber. This chamber takes some of the work away from the spring mechanism, allowing a smaller spring to be used which results in an easier breathe. As the chamber uses air to balance the valve it maintains the same resistance as the diver descends and ascends, keeping the inhalation effort the same.
|Weight in Grams (approx)|
?The weight includes the first stage (DIN fitting), hose and second stage.
