Lets Take A Closer Look At The Fist Stage

mk25 first Stage Scubapro says that  the Mk25 is their top performing first stage regulator, and uses a balance piston to deliver ultra stable intermediate pressure to the second stage, resulting in consistent performance at any tank pressure and depth.

What does this mean to you, the diver? Because the Mk25 delivers more air to the second stage than any other regulator,  it will perform the same in demanding dive conditions making  it perfect for recreational and professional divers alike.

The tired diver also benefits from a smoother breathing regulator during the ascent or deco stop as well.

The fist stage is manufactured from brass and plated with a high polished marine grade chrome. It  also features five low pressure ports on a 360 degrees swiveling turret (four on the side and 1 on top) for optimum house routing. This feature also help reduce jaw fatigue by reducing the tension on the low pressure hoses.

Two high pressure ports are located on either side of the reg. This allows you to position the gauges either on the right or left side and increases the freedom of movement for head and neck.

Although this first stage is not environmentally sealed, scubapro also claims that the regulator  will perform just as good in cold water diving conditions.  This is due to:

  • Scubapro Patented TIS System – Metal components inside the regulator are specially designed to restrict  ice crystal from forming on them, hence preventing freezing and the overall malfunction of the regulator.
  • Heat Sink – The ribs on the exterior of the first stage act as a radiator to increase the surface area of heat transfer from the water to warm up the internal parts that have been drastically cooled by the drop in pressure  when you breath from the regulator.

The first Stage also come equipped with an externally adjustable intermediate pressure,  which allows technicians to quickly fine tune  it without the need to disassemble the first stage.

The Mk25 is also nitrox compatible to 40% right out of the box, so there is no extra cost in buying a nitrox conversion kit.

Now Lets Look At Some Of The Features Of The Second Stage

Scubapro s600-2013Scubapro says that the  S600 is the perfect pair for the Mk25,  the fact that it is balanced and has adjustable features let the Mk25/S600 adapt to any diving condition.

Because a balanced second stage sightly offsets the force of the downstream air entering the second stage, it reducing the tension on the spring making it effortless to breath from the second stage.

A control knob on the side also allows you to adjust the inhalation effort of the second stage. 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.

The S600 is also equipped with Scubapro’s patent Venturi Initiated Vacuum Assist (VIVA). The VIVA switch in the “Max” position creates a vacuum in the second stage that greatly reduces inhalation efforts. The VIVA switch in the “Min” position will help prevent free flow on the surface or when it is used as an octopus.

The second stage also comes  with Scubapro’s orthodontic mouth piece which help prevent jaw fatigue by reducing the bite pressure needed to hold the regulator in place.

Other Version Of The MK25 S600

The Scubapro Mk25/S600 is now available in 4 other versions, the MK25/S600 Black Tech, the Mk 25/S600  Deep Blue, the Titanium MK25/s600, and the new MK25 EVO/S600.

Each version offer their own unique cosmetics, coating, and construction material, but they all have one thing in common – awesome performance.

Scubapro Mk25/S600 Black Tech

Scubapro Mk25 S600 Black TechThe Black Tech  is basically identical to the standard MK25/S600 and packs the same great performance. However,  Instead of a chrome finish it has a black PVD that gives a more tech look to the regulator.

The PVD is not only for cosmetics it offer greater scratch resistance than your standard chrome finish which can scratch pretty easy especially if you are diving in the tight spaces of  caves and wrecks.

Scubapro MK25/S600 Deep Blue

Scubapro Mk25 S600 Deep BlueThis versions still packs all the same performance you would expect for the Mk25/S600. However the S600 second stage has been made super lightweight and more corrosion resistance by using an Interior Titanium Valve Barrel.

It also has jewel-colored deep blue PVD finish. Not only does the PVD finishing look great, it also provides better scratch and corrosion resistance than standard chrome regulators.

Scubapro MK25T/S600T Titanium

Scubapro Mk25T-S600TThis system also offer the same performance as its brass versions, but in a super lightweight package.

The Mk25T first stage body and components are made from lightweight corrosion resistant titanium.  The second stage has also been upgraded with a titanium trim ring and plate.

Titanium is the lightest and most corrosion resistant metal used to constructing scuba regulators, this makes them perfect to use as a travel regulator.

Scubapro MK25 EVO/S600

Scubapro MK25 EVO S600The 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 cater,  without sacrificing its overall performance.

With this technology the EVO can withstand 30 percent colder water than the traditional MK25.

What Other Divers Are Saying About the Scubapro MK25 S600

The overall feedback on this regulator are excellent, there is hardly any negative review to report. Many divers fund that the regulator is very easy to breathe from, in any position, whether they where inverted or upside down, and  performed flawlessly at deep depth and low tank pressures.

The only complaint I was able to find was the price, this is not a cheap regulator, however if you can afford it, you cannot go wrong with this reg, even if you are just staring out.

Below are snippets of user reviews I have found on the internet.

 

“I have the same regulator with over 200 dives and now my wife has one because of the great experience I’ve had with mine. I’ve used it in the waters off Alaska to the Cayman’s and down to 150ft and it’s just a solid, smooth regulator with a very comfortable mouthpiece.”

“Dove this reg below 180 many times, right-side up, inverted and upside down it doesn’t matter this is my go to reg. A must have even for the most novice diver!”

“I’ve done about 20 dives on this reg. It works great. For what Lesiure Pro charges it’s a great deal, for what the shops charge – it’s probably an average high-end regulator. Wether I’m upside down, sideways, low on air, or deep, (I’ve had it to 135 fsw) it breaths effortlessly.”

“This is an awesome regulator. I personally like to tighten up the breathing because it lengthens my bottom time. THis can breathe real tight or simply flow – however you like it, you can set it. I would not trade it for anything else, my life depends on it so I got the best! I used it and I loved it.”

The Bottom Line

The Mk25/S600 is a top performing regulator, and  offer exceptional breathing at recreational depth but still have the capacity to perform when pushed to the extremes. Each version of this regulator offer its own style, but still deliver the same awesome performance.
