The A700 second stage, with its metal casing, screw-down cover, metal valve housing (barrel) and over-molded accents, exhibits a real muscularity in design.

• Rugged full metal second stage case and valve housing (barrel) are able to withstand years of aggressive diving.
• Metal second stage case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
• Air balanced second stage valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• Sectional exhaust tee and a first-rate purge help to deliver effortless inhalation and an ease of exhalation that is unmatched.
• User controls include a diver-adjustable inhalation effort knob and coaxial Venturi-Initiated Vacuum Assist (VIVA) switch.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
