Scubapro MK25 EVO/S600 Review Video
Below is a quick video review of the regulator done by the guys over at Simplyscuba.com. In the video, you can get a closer look at the regulator and some of its features.
Scubapro MK 25 EVO/S600 Key Features
Excellent Breathing Performance
The MK25 Evo uses a balance piston to deliver ultra stable intermediate pressure to the balanced S600 second stage, resulting in a consistent performance at any tank pressure and depth.
360 Degrees Swiveling Turret
It also features five low-pressure ports on a 360 degrees swiveling turret (four on the side and 1 on top) for optimum hose routing. This feature also helps reduce jaw fatigue by reducing the tension on the low-pressure hoses.
Increase Cold Water Protection
The MK25 EVO is designed with Scubapro’s new Extended Thermal Insulating System (XTIS) which fully isolates the important internal mechanisms from the environment. This greatly improves the ability of the regulator to resist freezing in colder water, without sacrificing its overall performance. With this technology, the EVO can withstand 30 percent colder water than the traditional MK25.
Diver Adjustable Second Stage
It also features a user adjustable venturi switch to easily manage free flows on the surface and breathing resistant knob to fine tune your breathing. In the “Max” position it allows the regulator to perform at its optimum performance. Turning the Knob to the “Min” position puts more tension on the spring, resulting in lower air flow rate, which is great for diving in cold water condition, and help prevent free flow while diving in heavy currents. The Knob is also big enough to be easily operated even while wearing thick gloves.

What We Like
It’s easy to see why this regulator is considered one of the top-performing regulator today. It has consistently gotten top ratings from reviewers for its exceptional performance and low work of breathing.
The second stage adjustment knob is easy to operate even while wearing thick gloves, and you can feel the adjustment almost immediately. Some people report that tightening up the breathing actually lengthens your bottom time. But, when you open it up, it is one of the best breathing regulators out there.
The swiveling turret also does help reduce tension on the second stage hose, and there was virtually no tugging when you turn your head like other regulators, which greatly helps with jaw fatigue.
It has 2 high-pressure ports on both sides of the regulator which allows you to mount the regulator in either direction. When mounted downwards, it makes the regulator more streamlined and reduces accidentally hitting you in the back of your head.
