By incorporating compensated valve technology, the A700 provides extraordinary breathing performance in a high-performance case and a hand-made, all-metal precision structure.


Rugged full metal case and valve housing (barrel) are able to withstand years of aggressive diving.

Metal construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.

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 coaxial-flow Venturi-Initiated Vacuum Assist (VIVA) lever.

Super-flow hose features an oversized bore 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): 9.2oz/261g.

Airflow at 2900psi: 2000 l/min - 71 SCFM.
