The Scubapro Carbon Black Tech MK25 EVO A700 Regulator is a very high performance regulator that is designed for cold conditions with a black scratch and corrosion resistant coating and a light weight Carbon fibre front cover. The MK25 first stage is paired with the metal bodied A700 second stage for effortless breathe and excellent cold water performance.


Black Tech PVD Coating gives the first and second stage a black technical look, that is extremely effective against scratches and corrosion. The Powder Vapour Deposit coating is applied in a near vacuum environment and the pigment penetrates the surface of the metal to improve it's qualities beyond the surface.

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 cold water 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 A700 2nd Stage features a full metal housing that is designed to offer excellent cold water performance as the metal construction allows the cold to be transferred to the surrounding water far quicker and more efficiently than normal plastic housings. The A700 allows the diver to independently adjust the venturi and inhalation resistance. The venturi control adjusts the flow of air within the housing, directing it toward the mouthpiece for optimal flow, or toward the diaphragm to aid closing the valve. The inhalation control increases or decreases the tension on the valve spring, making it harder or easier to breathe (the default position is tuned to provide optimal performance).

Scubapro Carbon Black Tech Mk25 Evo A700 Regulator - Features

FeatureProduct Specification
Adjustable Inhalation
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. Close.
Adjustable Venturi
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. Close.
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. Close.
Cold & Warm Water
Environmentally sealed
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. Close.
First Stage
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. Close.
High Pressure Ports
High pressure ports supply the pressure gauge and wireless transmitters for dive computers Close.
Low Pressure Ports
Low pressure ports supply the 2nd stages and inflator hoses Close.
Second Stage
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. Close.
Service Information
All regulators need to be serviced to keep them in working order as the parts inside them age and wear over time and with use. Most regulators need to be serviced once a year or after 100 dives with normal recreational use to replace parts and re-balance.

Some regulators use more modern materials or mechanisms that allow them to extend the servicing interval that can save you some money in the long run. Close.
2 Year - 100 Dives
Weight in Grams (approx)
The weight includes the first stage (DIN fitting), hose and second stage. Close.

Six stars

I would give this reg six stars if I could. I’ve been really pleased with the performance and the style. It breathes super easy underwater and adjusts to suit your needs. Other divers are constantly asking about it because it really is a beautiful piece of engineering. It’s super light which is great for travel. The only downside is the carbon scratches too easily. Mine now has a deep scratch from a careless handler. I would suggest looking after your own equipment.

Thing of beauty

Non stop comments and questions out on the dive boat. Not one your likely to see other divers using so it’s a good talking point ! Price might seem steep but at the end of the day it’s stunning and it’s scuba pro QUALITY

Having Traded up from an Old MK25AF and S600 it was suggested i wouldn''t notice the difference!! Well I did / you can first dive into 4.c water and it behaved perfectly with both adjustable inhalation control and vacuum assist set at it most conserv

A little lighter than my chrome a700 but that doesn''t really make a difference when you''re in the water. Looking forward to seeing if the carbon gets as easily scratched as the chrome one. Great quality as you''d expect from scubapro
