Gear & Advice You Can Trust

A compact piston first stage teamed with a full-featured rugged nylon fiberglass second stage with freeze resistant components equals an easy- breathing reg system with power to spare. It’s a proven performer for all types of diving, but where the MK21/G260 really excels is in cold-water diving scenarios and technical applications. 

 

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% 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, allow 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 increas- es 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 eas- ier mounting on a cylinder, and a redesigned cap protects internal components from water intrusion after the dive.
  • Available in a 3364psi/232bar INT configuration.
  • Weight: INT 232 (oz/g): 26.2/744.
  • Airflow at 2900psi/200bar: (l/min/ SCFM): >7500/265.
  • Intermediate pressure (psi/bar): 130-142/9.0-9.8. 

Second Stage

• Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.

• Nylon fiberglass design features SCUBAPRO’s largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position

in the water.

• Anodized aluminum front cover ring adds resistance without adding weight.

• Metal air barrel and in- creases resistance to freezing when diving in extreme conditions.

• High-flow exhaust valve reduces exhala- tion for better overall breathing comfort.

• A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and per- sonal tastes.

• Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch pre- vents free flows in cold water or when used as an octopus.

• Reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.

• Super-flow hose features an over- sized bore that allows more air to flow on each inhalation.

• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.

• Weight: 9.7oz/275g.

• Airflow at 2900psi/200bar: 1800 l/min - 64 SCFM.

• Maximum low pressure: 203psi/14bar.

Check out SCUBAPRO’s new balanced piston MK21. About 20 percent smaller than the MK25, this compact first stage offers a modern design that includes a “smart” hose layout. High airflow delivery minimizes breathing effort, regardless of depth or tank pressure. The MK21 also offers very good freezing resistance due to its external fin design. http://www.scubapro.com/en-US/USA/regulators/products/mk21g260.aspx http://www.scubapro.com/en-US/USA/regulators/products/mk21s560.aspx
