Scubapro MK17 EVO S600 Regulator

The MK17 EVO S600 regulator takes Scubapro's top level balanced diaphragm 1st stage and pairs it with their most popular premium 2nd stage. 

The MK17 Evo 1st stage is Scubapro's premium performance balanced diaphragm 1st stage. This 1st stage is designed to work with pretty much anything that can be thrown at it with it's environmentally sealed design preventing any water entering the body. This 1st stage excels in cold water, and laughs at freezing lakes! 

The S600 2nd stage is an example of exceptional engineering being refined with each version. The current S600 has a fibreglass body with a stainless steel front face for durability and a metal air barrel for performance. This air balanced valve provides easy breathing at all depths, and has responsive user adjustments. This is a 2nd stage for divers who want the best. 

Tech Info

MK17 EVO First Stage:

• Air balanced diaphragm delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Environmentally sealed system prevents water and pollutants from fouling the inner mechanism.
• More compact design features a smaller dry ambient pressure chamber and spring, although the bulletproof inner parts remain the same.
• Dry ambient pressure chamber increases freezing resistance, ensuring consistent airflow in the coldest conditions.
• Substantial increase in airflow -- 6900 l/min versus 6500 l/min -- includes improved balance of air supply pressure.
• Two high pressure and four high-flow ports maximise air delivery and hose routing options.
• High-flow performance is available from all four LP ports which are configured for optimum hose routing.
• Available in a 3364psi/232bar INT configuration.
• Weight: INT 232 - 30.3oz/860g.
• Airflow at 2900psi/200bar: 6900 l/ min - 242 SCFM.
• Intermediate pressure (psi/bar): 133-142/9.2-9.8.

S600 Second Stage:

• Metal valve housing (barrel) is able to withstand years of aggressive diving.
• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• 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.
• Weight (without mouthpiece): 7.1oz/200g.
• Airflow at 2900psi/200bar: 1850 l/min - 66 SCFM.
• Interchangeable purge covers allow you to make your regulator truly unique.
