Scubapro S600 Second Stage Regulator

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. The air-balanced valve technology of S600 second stage features a balancing chamber in the second stage mechanism, slightly offsetting the force of the downstream air entering from the first stage. This allows reduced spring tension and decreases the inhalation resistance to the lowest possible level. The result is super smooth breathing in all conditions.

Precision moulded carbon fiber & technopolymer housing: low friction, light weight, corrosion and cold water resistant for long life & sturdiness. Diver adjustable inhalation effort. This feature enables the diver to adjust breathing effort via an oversized control knob.

• Metal valve housing is able to withstand years of aggressive diving.
• 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 Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
• Interchangeable purge covers allow you to make your regulator truly unique.
• Weight: 6.8oz/193g.
• Airflow at 2900psi/200bar: 1850 l/min - 66 SCFM.
• Maximum low pressure: 203psi/14bar.
