Technical Information

DETAILS

MK25 EVO BLACK TECH First Stage:

  • Extremely scratch and corrosion resistant, the Black Tech coating protects and lends a technical look to the first stage.
  • Air-balanced flow-through piston design delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
  • Patent-pending XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the current MK25 without compromising breathing performance.
  • New spring insulating coating, body insulating bushing (non-metal cylindrical interface separating metal parts from water), anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance.
  • Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
  • Two high pressure and five high-flow low pressure ports on a swivel turret maximize hose routing options (high flow ports deliver about 15 percent more air than conventional LP ports).
  • External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily without the need for disassembly.
  • Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
  • Weight: INT 232 (oz/g): 29.1/825; DIN 300 (oz/g): 20.9/592.
  • Airflow at 2900psi (l/min/SCFM): >8500/301.
  • Intermediate pressure (psi/bar): 130-142/9-9.8.


S600 BLACK TECH Second Stage:

  • Extremely scratch and corrosion resistant, the Black Tech coating protects and lends a technical look to the first stage.
  • Full metal valve housing is able to withstand years of aggressive diving.
  • Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
  • User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.
  • Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.
  • Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.

 

TECHNICAL INFO

MK25 EVO BT

  • 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.
  • Two opposite high pressure ports. The arrangement of high and low pressure hoses is crucial to diving comfort. Two opposite high pressure ports allow you to position the first stage either pointing up or down. This lets you run your gauges either on your right or left side plus 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 offers five HF (high flow) ports on a swiveling turret, which allows for 360 degree swivel of hoses.
  • DIN/INT first stage configurations. To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 232bar INT version as well as 300bar DIN versions.

S600BT

  • A quality second stage can significantly reduce stress and enhance diver safety by providing a smooth, low-effort breathing response, resulting in ample yet controllable quantities of air.
  • The air-balanced valve technology of SCUBAPRO's S600 second stage features a balancing chamber in the second stage mechanism, slightly offsetting the force of the downstream air entering from the first stage.
  • The S600's precision molded carbon fiber and technopolymer housing offers low friction, light weight and corrosion and cold water resistance for long life.
  • The diver adjustable inhalation effort control knob enables you to adjust the breathing effort to match dive conditions
  • SCUBAPRO's patented Venturi Initiated Vacuum Assist (VIVA) uses the power of a vacuum assist to reduce work of breathing and increase breathing comfort.
  • SCUBAPRO uses a comfortable orthodontic mouthpiece on the S600 to reduce jaw fatigue and gum irritation. It was developed by dentists and dental laboratories and lasts longer than any other mouthpiece, because only minimal effort is required to hold it comfortably in place.
  • A sturdy high flow hose with kevlar lining offers extra durability and maximum airflow.

AN UNBEATABLE BREATHER

Popular reg system features a protective stealth coating and a cool tech look.

SCUBAPRO has teamed its flagship first stage, the MK25 EVO, with its best selling second stage, the S600, then added a "Black Tech" scratch- and corrosion-resistant coating to protect this popular reg system from the rigors of tech diving.

There's no better example of supremely solid first stage performance than the MK25. This air-balanced flow-through piston design provides consistent and effortless airflow regardless of depth, tank pressure, or breathing rate. And now, with the introduction of the new patent-pending Extended Thermal Insulating System (XTIS), the MK25 EVO lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow - regardless of how cold the water is. The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over the current MK25 without compromising breathing performance. This makes the MK25 EVO the ultimate do-it-all first stage for all water temperatures.

The air balanced S600 second stage delivers effortless inhalation and exhalation. It's lightweight in the mouth and it's easy to use, with efficient user controls that include a powerful purge, an inhalation effort control knob and Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive switch.

Put them together and you have a high performance reg system known for its low work of breathing and tremendous reserve capacity. With the long-lasting Black Tech coating providing protection from the ravages of salt water and corrosion, the MK25 EVO/S600 BLACK TECH becomes the ultimate go-anywhere reg, able to face down the most demanding dive conditions and surface without a scratch.
