Price: $493.00
Item Number: 12.978.000

MK 21 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 easier mounting on a cylinder, and 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.

C350 Second Stage:

  • Compact body and exhaust tee take up little space in a travel dive bag.
  • Stainless steel frame on the front cover adds some style to the compact design.
  • Classic downstream valve design.
  • User controls include a coaxial-flow diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA).
  • New dive/pre-dive switch clip makes the assembly more reliable than ever.
  • Large purge button is easy to activate, even wearing thick gloves.
  • Holes below the purge button increase water circulation on the diaphragm to improve sensitivity.
  • Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
  • Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
  • Weight: 7.1oz/201g.
  • Airflow at 2900psi/200bar: 1550 l/min - 55 SCFM.
