- Delivery & Returns
The MK25T first stage has a balanced through-flow piston design that is capable of delivering incredible gas flow rates regardless of depth, cylinder pressure or breathing rate. The first stage uses a combination of anti-freeze coatings and components to meet and surpass the requirements for cold water rating. It is fitted with four low-pressure high flow ports around the outside of a swivelling turret and a fifth port on the end that provides optimal hose routing for technical diving. Two opposing high-pressure ports allow the first stage to be positioned either up or down.
The S620 X-Ti second stage is an evolution of the S600. It features a new titanium valve inlet tube that is lighter and corrosion-resistant and a smaller housing design that utilises the same diaphragm as the S600 for outstanding performance. The second stage uses a pneumatically balanced valve design for a smooth breathe that can be tailored by adjusting the inhalation effort control knob. There is also a lever to adjust the venturi effect with the housing, allowing it to be switched to Pre-Dive for water entry and reduced risk of freeflow or Dive mode for optimal performance and gas flow to the mouthpiece.
