- Air balanced flow-through piston first stage 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 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.
- Air balanced second stage valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
- Lightweight reinforced technopolymer casing helps reduce jaw fatigue and improve diving comfort.
- Technopolymer inlet tube contributes to reliability and long life.
- High flow exhaust valve reduces exhalation effort to lower overall work of breathing.
