MK17 EVO First Stage:
S600 Second Stage
The new MK17 EVO is SCUBAPRO's premium high performance balanced diaphragm first stage. Engineered specifically for cold water and harsh environments, its internal components are completely sealed off from the elements so neither water nor pollution can get inside the chrome-plated marine grade brass body to foul the mechanism.
This total sealing system also allows for a dry ambient pressure chamber which works to prevent freezing, provides better protection and improves performance, ensuring trouble-free operation no matter how cold or murky the water gets.
This new version is more compact than its predecessor yet delivers better breathing performance. Its improved internal design allows more airflow from the LP ports which have also been configured for optimum hose routing.
S600 SECOND STAGE
A second stage regulator must translate natural breathing behaviour into mechanical reality. A high quality second stage can significantly reduce stress and enhance diver safety by providing smooth, low-effort breathing response, resulting in ample yet controllable quantities of air.
The designation balanced and classic downstream are also distinguishing marks for second stages and again imply ultimate flow performance and stability in addition to reliability, simplicity and solid performance.
