The MK25 EVO/S620 Ti is SCUBAPRO's flagship system for demanding dives. Its full titanium inlet tube resists corrosion, the environmentally sealed first stage prevents freeze-up in cold water, and the S620 Ti second stage delivers effortless airflow at any depth. It is the top choice for performance divers who dive across a wide range of conditions.

A factory-matched regulator system — first stage, second stage, and octopus — is engineered to deliver balanced airflow, consistent intermediate pressure, and reliable performance as a unit. Buying a complete system also simplifies servicing, ensures component compatibility, and during the Regulator Event, includes a free R105 Octopus to round out your setup.

SCUBAPRO regulators are designed, tested, and serviced as complete systems rather than individual components. Key differentiators include environmentally sealed first stages for cold-water reliability, titanium construction for corrosion resistance and reduced weight, and a global authorized service network. The Regulator Event makes it an ideal time to step up from other brands with a complimentary octopus included.

The R105 is SCUBAPRO's dedicated octopus (alternate air source) — a compact, high-visibility second stage designed for emergency air sharing. Every open-water diver needs an octopus as part of a complete regulator system. During the Regulator Event, the R105 is included free with qualifying regulator system purchases, completing your setup at no additional cost.

All SCUBAPRO regulators are backed by a limited lifetime warranty - see conditions.
