About Scubapro MK25/G250V Regulator

SCUBAPRO has been the leader in the evolution of piston controlled first stages since its beginning; the MK25 carries on this heritage with an array of patented features ensuring unfailing performance The MK25 is a balanced piston first stage, our absolutetop performer It is a superior regulator thanks to its ultra stable intermediate pressure resulting in an extremely punctual and constantly high delivery of air This means instant airflow at any tank pressure and water temperature for a real carefree dive Air balanced flow-through piston- First stages with air balanced pistons deliver significantly more air to the second stage than anyother first stage, while their performance is totally unaffected by the changing tank pressure A balanced piston allows the use of lighter and more sensitive components, resulting in ultra fast breathing response, instant delivery of air on demand, and extra highair flow, especially in low tank pressure ranges The tired diver benefits from a smoother breathing regulator during the ascent or deco stop Balanced piston first stages are the first choice of demanding sport divers and professionals A balanced piston performsequally in warm and cold water environments Two opposite high pressure ports- The arrangement of high and low pressure hoses is crucial to diving comfort Two opposite high pressure ports allow for an individual positioning of the first stage (pointing up or down) This allows the diver to position the gauges either on the right or left side and increases the freedom of movement for head and neck Multiple low pressure ports- For ultimate freedom in the arrangement of low pressure hoses, the MK25 accommodates five HF (high flow) ports on a swiveling turret, which allows for 360 degree swivel of hoses High flow ports deliver about 15% more air than conventional ports Externally adjustable intermediate pressure- Allows authorized SCUBAPRO service technicians to quickly finetune and adjusts the first stage after maintenance without the need to disassemble it

The G250V uses SCUBAPRO'S Air-balanced valve technology The air-balanced valve technology of SCUBAPRO's second stages features a balancing chamber in the second stage mechanism, slightly offsetting the force of the downstream air entering from the first stage This allows reduced spring tension and decreases the inhalation resistance to the lowest possible level The result is super smooth breathing in all conditions Diver adjustable inhalation effort, this feature enables the diver to adjust breathing effort via an oversized control knob; it is available on the G250 second stage Venturi Initiated Vacuum Assist (VIVA) Another SCUBAPRO patented feature, the VIVA is available on the G250V second stage VIVA uses the power of a vacuum assist to reduce work of breathing and increase breathing comfort A VIVA in MAX position gives powerful breathing support on every single breath; a VIVA in MIN position helps to prevent free flow on the surface, for training, for buddy breathing, in currents, or when used as an octopus Orthodontic mouthpiece SCUBAPRO uses a comfortable orthodontic mouthpiece on every second stage to reduce jaw fatigue and gum irritation It wasdeveloped by dentists and dental laboratories and lasts longer than any other mouthpiece, because only a minimum effort is needed tohold it comfortably in place

            Sadly Scuba Pro will not warranty this regulator bought on this site. This store/site are GREAT! Big LOSS on Scuba Pro's Part, they (Scuba Pro) needs to re-evaluate their internet policies! Leisure Pro has done nothing but be an excelent all around store. Please continue to support them. I know I am!

            Don't know if Scubapro will honor any warranty as [...] Got it a a very good price so I hope that makes up for any out of pocket I might have.

              Questions about this item:

              Shopper  Why Did You Choose This?
              JOSHUA D  This was the first regulator I bought. I can say that I made a great choice. This is still a go to reg for the tech diving crowd with one modification. Get the DIN valve with a converter. DIN is just a superior connection in every way. Highly recommended and I bought two more MK25 regs when I started doing my tech courses.
              Shopper  I saw where this was Nitrox compatible to 100%. In another Q&A here it's stated to be compatible to 40%. My friends say get one that's 100% (or 99%) Nitrox ready. Should I be considering this one if it's only 40% ready for NITROX?
              JERRY H  According to the Scubapro catalog, all SP regs are Nitrox ready up to a 40% mixture, up to 3300 PSI right out of the box. The two most common recreational diving nitrox mixes contain 32% and 36% oxygen. Nitrox with more than 40% oxygen is uncommon within recreational diving. I would also contact your local scuba dealer who should be a wealth of information. My wife and I both use the MK25/G250V for both air and nitrox and have had no problems. We like it so much that we will buy the MK25 for our children when they start diving in a few years.
              Shopper  Is there a converter for this reg?
              LeisurePro S  The DIN converter for this regulator can be found here.
