The MK25 EVO and S600 second stage regulator from Scubapro is a top-performing diving system, offering ultra-high airflow and unbeatable performance in all temperatures and diving conditions. The MK25 EVO is a balanced piston first stage and Scubapro's best-performing regulator, with an ultra-stable intermediate pressure for constant high air delivery. This means instant air flow at any tank pressure and water temperature for a hassle-free dive.

The MK25 EVO has two opposite high-pressure ports and multiple low-pressure ports, providing ultimate freedom in hose arrangement. It also has a swiveling turret with high flow ports for increased air delivery. The regulator is cold water tested, meeting EN250-2014 requirements, and has been improved with Scubapro's new Extended Thermal Insulating System (XTIS), making it more resistant to freezing. The system offers superior cold water performance, making it the perfect option for divers who demand high performance in cold water environments.

The S600 is a versatile regulator, with a linear air balancing valve and adjustable inhalation control. It is easy to use, with a Venturi initiated vacuum assist switch and extra high flow exhaust valve. The regulator is lightweight, anti-freeze, and comes with a comfortable mouthpiece.

In conclusion, the MK25 EVO and S600 system is a top-performing, high-quality dive system that is perfect for divers who demand the best in performance and convenience. Whether diving in warm or cold water, this system is sure to provide a positive diving experience.

• 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.
