AN EXCELLENT REGULATOR SYSTEM - NOW WITH A SPLASH OF COLOUR

The S600, with its rugged fiberglass casing and stainless steel front face and ring, delivers smooth and easy inhalation and exhalation while offering efficient user controls, including a powerful purge, an inhalation effort control knob and Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive switch. It provides a steady, effortless flow of air, regardless of depth or workload.

Now you can spice up your MK21/S600 system with interchangeable S600 purge covers in a choice of colors (Blue, White, Yellow, Red and Pink). Pick  a color that celebrates your diving style!

The compact and lightweight MK21/S560 is a full-featured reg combo that's easy to use, offers SCUBAPRO reliability and is priced right, making it the ideal mid-range system for a variety of diving scenarios.

The MK21 is SCUBAPRO's most compact balanced-piston first stage. Smaller and lighter than the MK25, it uses a smaller piston but it delivers the same level of breathing performance, no matter how hard you're breathing, how deep you're diving or what your pressure gauge reads. The MK21 also provides exceptional resistance to freezing due to the thermal exchange produced by the external fins on its polished chrome brass body.

The MK21's innovative "smart" hose layout comes with a standard cap with four low pressure ports angled (+/- 20º) to maximize hose routing. This standard cap can be replaced with an optional cap that offers four low pressure ports at more extreme angles (0°/30°) plus a fifth centralized high-flow low pressure port -- a useful configuration for technical diving.

 

 

Technical Information

MK21 First Stage:

 

  • Air-balanced flow-through piston provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
  • Polished chrome plated marine grade brass body is close to 20 percent smaller than the MK25, making it an easy travel companion.
  • Unique thermal exchange design with external fins optimizes freezing resistance.
  • Two high pressure ports, one on each side of the body, allows the first stage to be positioned either up or down.
  • Standard "smart" hose routing cap offers four low pressure ports angled for more convenient hose routing (+/- 20º).
  • Optional hose routing cap increases routing configurations with four angled low pressure ports  (0°/30°) plus a fifth centralized high-flow low pressure port, ideal for technical diving.
  • Redesigned yoke allows for easier mounting on a cylinder, and redesigned cap protects internal components from water intrusion after the dive.
  • Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
  • Weight: INT 232 (oz/g): 27.5/780; DIN 300 (oz/g): 19.7/560.
  • Airflow at 2900psi/200bar: (l/min/SCFM): >7500/265.
  • Intermediate pressure (psi/bar): 133-142/9.2-9.8.

S600 Second Stage:

 

  • Metal valve housing (barrel) 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.
  • Weight (without mouthpiece): 7.1oz/200g.
  • Airflow at 2900psi/200bar: 1850 l/min - 66 SCFM.
  • Interchangeable purge covers allow you to make your regulator truly unique.
  • Available purge cover colors: Blue, White, Yellow, Red, Pink.
