Short Description: 
SCUBAPRO’s top regulator technology is on display in this high-tech, ultralight reg system. The MK25T EVO is machined from a solid block of titanium which will not corrode, even in concentrated saltwater conditions, promising years of trouble-free use. It offers excellent resistance to freezing, superb inhalation sensitivity and instant delivery of air on demand. The new S620 X-Ti embraces the best features of SCUBAPRO’s renowned S600 in an upgraded, state-of-the-art design. Smaller and lighter but using the same-sized diaphragm, the S620 X-Ti delivers effortless airflow under all dive conditions. The titanium inlet tube is super-efficient, the large purge button improves water circulation and the new exhaust tee enhances overall performance.

Titanium Components
  1. 1
    Machined titanium body is lightweight, highly resistant to corrosion and ultra-durable.

  5. 5
    External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.

    Air balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
  7. 7
    Rugged reinforced technopolymer case and front cover with stainless steel frame looks good plus is able to withstand years of aggressive diving.
  8. 8
    Full titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.

HI, can this titanium reg be used for recreational nitrox (less than 40%)

Asked by: rodlee
Yes, in the USA, the MK25T can only be used up to 40% oxygen. There are different standards in other countries, so please be sure to check with your local distributor. Thank you for your question.
