MK25 EVO/S600 Dive Regulator System
Pairs well with
Overview
SCUBAPRO's best-selling air balanced second stage and its top-performing air balanced piston first stage is a match made in diver heaven. Well-known for its low work of breathing, year after year this combo has consistently ranked as one of the top-performing reg systems on the market. The MK25 EVO first stage lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and impressive airflow. The S600 delivers smooth and easy inhalation and exhalation while offering efficient user controls, including a powerful purge, an inhalation effort control knob and Venturi Initiated Vacuum Assist (VIVA). Together they provide a steady flow of air, regardless of depth, water temperature, or workload.
FEATURES
- Air balanced flow-through piston in a chrome plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
- Patented XTIS (Extended thermal Insulating system) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing performance.
- Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
- Two opposing high pressure ports allow the first stage to be positioned either up or down.
- Four high-flow and one axial super high-flow low pressure ports on a swivel turret maximize hose routing options.
- External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
- Air balanced second stage valve smooths out the inhalation effort at varying depths and supply pressures.
- Second stage’s rugged reinforced technopolymer case and front cover with stainless steel frame looks good plus is extremely durable.
- Metal valve housing (barrel) is able to withstand years of aggressive diving.
- User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.
- Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.
- Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.

Frequently Asked Questions
FAQs
What is the SCUBAPRO Regulator Event?
Purchase a qualifying regulator system and receive a free R105 Octopus. See full terms and conditions.
Qualifying Regulators: MK17 EVO 2/S620 Ti, MK25 EVO/S620 Ti, MK17 EVO 2/G260, MK19 EVO/G260, MK25 EVO/G260, MK19 EVO/A700, MK25 EVO/A700, MK25 EVO/S600. The R105 Octopus will automatically get added to the shopping cart when a qualifying regulator system is added.
What is the best SCUBAPRO regulator for cold water and demanding conditions?
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.
Why should I buy a complete regulator system instead of individual components?
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.
How does SCUBAPRO compare to other regulator brands?
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.
What is the R105 Octopus and why do I need one?
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.
Do promotional regulators include the same warranty coverage?
All SCUBAPRO regulators are backed by a limited lifetime warranty - see conditions.
