The Scuba Pro MK25/S600 Regulator, SCUBAPRO has been the leader in the evolution of piston controlled first stages since its beginning; the MK25 carries on this heritage with an array of patented features ensuring unfailing performance. The MK25 is a balanced piston first stage, SCUBAPRO's absolute top performer. It is a superior regulator thanks to its ultra stable intermediate pressure resulting in an extremely punctual and constantly high delivery of air. This means instant airflow at any tank pressure and water temperature for a real carefree dive.
Air balanced flow-through piston- First stages with air balanced pistons deliver significantly more air to the second stage than any other first stage, while their performance is totally unaffected by the changing tank pressure. A balanced piston allows the use of lighter and more sensitive components, resulting in ultra fast breathing response, instant delivery of air on demand, and extra high air flow, especially in low tank pressure ranges. The tired diver benefits from a smoother breathing regulator during the ascent or deco stop. Balanced piston first stages are the first choice of demanding sport divers and professionals. A balanced piston performs equally in warm and cold water environments.
The MK25 has two opposite high pressure ports- The arrangement of high and low pressure hoses is crucial to diving comfort. Two opposite high pressure ports allow for an individual positioning of the first stage (pointing up or down). This allows the diver to position the gauges either on the right or left side and increases the freedom of movement for head and neck. Multiple low pressure ports- For ultimate freedom in the arrangement of low pressure hoses, the MK25 accommodates five HF (high flow) ports on a swiveling turret, which allows for 360 degree swivel of hoses. High flow ports deliver about 15% more air than conventional ports. Externally adjustable intermediate pressure- Allows authorized SCUBAPRO service technicians to quickly fine-tune and adjusts the first stage after maintenance without the need to disassemble it.
Cold Water Diving with SCUBAPRO-Diving conditions can be drastically different, including extreme cold water and outside temperatures, posing the possibility of a regulator "freezing". Therefore, resistance to freezing is imperative for the diver. All SCUBAPRO regulator systems are CE approved for 4300psi (300 bars) cold water diving. Some models go even beyond this super stringent qualification and have successfully been tested in extreme cold diving conditions at less than 36°F (2.2°C). As a specific anti-freezing measure, SCUBAPRO engineers have designed a patented finned cap for the MK25 first stages for optimal cold water diving. This finned cap is a Thermal Insulating System (TIS).The ribs of the TIS act as a radiator to increase the surface area of heat transfer from the water to warm up the internal parts that have been drastically cooled down by the gas pressure drop. The MK25 is manufactured from Marine-Grade Chrome Plated Brass. The MK25 First Stage offers a Machined, Marine-Grade Gold Chrome Plated Body and Balanced Composite/Stainless Steel Flow-Thru Piston that would make any diver proud. It demonstrates SCUBAPRO's dedication to quality and creating positive diving experiences.
Because of the S600's Versatility, it can meet the diver's needs as frequently as the diver changes dive sites. The S600 is constructed of a Chrome-Plated Brass and Techno-Polymer Valve Housing, a Linear Air-Balancing Valve, and a top notch Air-Balancing System. This regulator's Air-Balanced Linear-Flow Valve allows the diver to use Less-Energy while Breathing Underwater; it makes breathing during a dive as simple as well, breathing in and out.
The S600 has a Diver Adjustable Inhalation Control that enables personal Adjustment of Breathing Effort. The S600's Diver Adjustable Venturi Initiated Vacuum Assist (VIVA) Dive/Pre-Dive Control Switch and Extra High Flow Exhaust Valve account for Easy Inhalation & Exhalation at any Depth or Breathing Rate. The Regulator comes equipped with a 3/8" threaded Super-Flow Hose for Smooth Air Delivery. Precision Molded, Lightweight Components and Anti-Freeze Materials provide High Corrosion Resistance and Enhance Cold Water Performance. The Second Stage is equipped with a Comfortable Orthodontic Mouthpiece. The Regulator weighs 27.7 oz (785 g) comes with an Owner's Manual and a Limited Lifetime Warranty.
