The Scubapro S600 Second Stage is constructed from a rugged fibreglass casing, and a  stainless steel front face. It delivers smooth, easy inhalation, and exhalation while offering efficient user controls. It also includes a powerful purge, an inhalation effort control knob, and Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive switch. It provides a steady, effortless flow of air, regardless of depth or workload.

This is just the second stage alone for divers who prefer to have a similar alternate air source, or for divers using single tank long hose configuration, that want a Scubapro S600  Second Stage as a back up regulator. (Please ensure that you have proper training prior to using a long hose back up regulator configuration)
