  MK25/A700 SYSTEM

  The MK25 teamed with our exceptional new A700, offers superior ultra-high airflow system for maximum performance in all temperatures and diving conditions.  SCUBAPRO is synonymous with piston-controlled first stages.  Our MK25 underscores this heritage with an array of proprietary features ensuring outstanding performance.  The MK25 balanced piston first stage is our absolute to performer, making this system our very best.

• Air balanced flow-through piston provides constant and effortless airflow unaffected by changing tank pressure
• Polished chrome edition, available exclusively with the A700 system, has 5 low pressure and 2 high pressure ports plus swivelling turret for convenient hose arrangement.
• Unparalleled breathing performance for the A700 at virtually any depth, temperature, and diving position
• Work of breathing results are 0.49
• Full metal body and components assure the best thermal exchange
• Compact dimensions for lightweight comfort
• 
  
• Air balanced flow-through piston - First stages with air balanced pistons deliver significantly more air to the second stage than any other 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 high air 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 performs equally 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 MK25MK17MK11 feature four stationary low pressure ports, two of them HF. High flow ports deliver about 15% more air than conventional ports. accommodates five HF (high flow) ports on a swiveling turret, which allows for 360 degree swivel of hoses. The and
• DIN/INT first stage configurations - To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 200bar INT version as well as 300bar DIN versions.
• Externally adjustable intermediate pressure - Allows authorized SCUBAPRO service technicians to quickly fine tune or make adjustments after maintenance without the need to disassemble the first stage.

A700

• Unparalleled breathing performance at virtually any depth, temperature, and diving position
• Work of breathing results are 0.49
• Full-metal body and components assure best thermal exchange
• Compact dimensions for lightweight comfort
• Air-balanced valve technology decreases inhalation resistance to the lowest possible, resulting in ultra-smooth breathing
• Diver-adjustable inhalation enables personalized breathing control
• Newly aligned VIVA system with micrometric adjustment knob for more precise control and comfort
• Super high-flow exhaust valve allows air to exit more freely and lowers exhalation effort-helps keeps bubbles away from face and eyes

MK25/S600

Our top performing balanced piston first stage paired with our best-selling high performance air balanced second stage; this combination is SCUBAPRO’s ultimate regulator combination. The S600 truly matches the MK25’s characteristics and, thanks to its adjustment possibilities, it adapts to all diving conditions and all diver preferences. Ease of breathing is the essence of this system:

• Balanced flow valve provides constant & effortless air flow.
• Diver adjustable inhalation control enables personal adjustment of breathing effort.
• Diver adjustable Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive control switch and extra high flow exhaust valve account for easy inhale & exhale.
• Super-flow hose for smooth air delivery.

In addition, precision molded, lightweight components, and anti-freeze materials provide high corrosion resistance and enhance cold water performance.

S600

• 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. The air-balanced valve technology is featured in the X and S-Series second stages. For best results they should be combined with balanced first stages, like the MK25 or MK17.
• Diver adjustable inhalation effort. This feature enables the diver to adjust breathing effort via an oversized control knob; it is available on the X650, S600, and G250 second stages. All other second stages feature a pre-set inhalation effort that suits the most common diving conditions and can be fine tuned at an Authorized SCUBAPRO Dealer on request.
• Venturi Initiated Vacuum Assist (VIVA). Another SCUBAPRO patented feature, the VIVA is available on all SCUBAPRO second stages. VIVA uses the power of a vacuum assist to reduce work of breathing and increase breathing comfort. It is diver adjustable on all current SCUBAPRO second stages except the R295, since it is a second stage intentionally designed for diver training courses, rental facilities, and divers demanding ready to use equipment. 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 was developed by dentists and dental laboratories and lasts longer than any other mouthpiece, because only a minimum effort is needed to hold it comfortably in place.

MK2PLUS/R295

The SCUBAPRO “workhorse”, MK2 PLUS was first introduced onto the market in 1962. This classic downstream piston remains as popular as ever, especially in schools and training centers. The simplest first stage piston mechanism ever, with fantastic performance and easy maintenance. The MK2 PLUS comes in a very compact design for a simple and reliable package that remains unmatched.

MK2 plus and the R-Series

Intro to diving

A classic downstream piston coupled with a classic downstream second stage means reliability, durability and easy care. This is the system of choice for training centers as well as new divers.  The R295 builds on the R190 core features and integrates a captivating compact design. Diving centers will appreciate a hassle-free fixed VIVA and left or right hose attachments for total flexibility of use, coupled with low maintenance.

MK2PLUS

• Classic downstream piston- The best example of bulletproof reliability and trouble-free, minimum maintenance regulators.  The classic downstream piston configuration is the simplest mechanism that exists to control the pressure drop from a tank to feed the second stage.  The classic downstream valve is the first choice of diving centers and rental facilities worldwide for warm and moderate water temperatures.
• DIN/INT first stage configurations. To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 200bar INT version as well as 300bar DIN versions.

R295

R295 SECOND STAGE REGULATOR

• Classic downstream valve. Classic downstream valves are particularly noted for their legendary safety and reliability. When in use, the downstream valve opens in the same direction as the incoming air flow. To close the valve and stop the air flow, a spring counteracts the force of the incoming air. Therefore, a certain inhalation effort is always required to overcome the spring tension and open the valve.
• Fixed VIVA (Venturi Initiated Vacuum Assist) flow vane.  Fixed in the pre-tuned ideal position for safe and uncomplicated use.
• Extremely lightweight and compact.  Comfortable for all divers, including novice divers newly initiated  in        the sport.
• Orthodontic mouthpiece. SCUBAPRO uses a comfortable orthodontic mouthpiece on every second stage to reduce jaw fatigue and gum irritation. It was developed by dentists and dental laboratories and lasts longer than any other mouthpiece, because only a minimum effort is needed to hold it comfortably in place.
