• 1st stage: The 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.

    2nd stage: the A700’s is an air-balanced regulator. Its casing is full metal to take advantage of the extremely high heat exchange rate which makes this second stage such a great choice for cold-water diving. In addition the metal case construction enables the use of a larger diaphragm inside a very compact casing for an ease of exhalation that is unmatched. The air-balanced system provides effortless breathing in any situation.
