SECOND STAGE REGULATORS

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.ir-balanced valve technology.

S555 SECOND STAGE-ALL ROUNDER

Air balanced technology for high breathing performance, yet simple to operatefor fun and relaxation on every dive. Initiates air flow effortlessly and instantly on demand. Remarkably durable and reliable, compact and lightweight.

· Air-balanced valve technology. The air-balanced valve technology of SCUBAPRO-s second stages 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. The air-balanced valve technology is featured in the X and S-Series second stages. For best results they should be combined with balanced first stages, like the MK25 or MK17.

· Venturi Initiated Vacuum Assist (VIVA). Another SCUBAPRO patented feature, the VIVA is available on all SCUBAPRO second stages. VIVA uses the power of a vacuum assist to reduce work of breathing and increase breathing comfort. It is diver adjustable on all current SCUBAPRO second stages except the R295, since it is a second stage intentionally designed for diver training courses, rental facilities, and divers demanding ready to use equipment. A VIVA in MAX position gives powerful breathing support on every single breath a VIVA in MIN position helps to prevent free flow on the surface, for training, for buddy breathing, in currents, or when used as an octopus.

· Orthodontic mouthpiece. SCUBAPRO uses a comfortable orthodontic mouthpiece on every second stage to reduce jaw fatigue and gum irritation. It was developed by dentists and dental laboratories and lasts longer than any other mouthpiece, because only a minimum effort is needed to hold it comfortably in place.


· Precision moulded carbon fiber & technopolymer housing: low friction, light weight, corrosion and cold water resistant for long life & sturdiness.

Scubapro R295 Second Stage

Scubapro R295 Second Stage. R295 SECOND STAGE

Compact, light and easy to carry, follows your diving passion nywhere. R295 second stage has fixed VIVA for truly carefree diving. Left and right hose attachments for total flexibility of use make them ideal for new divers and schools.

·Classic downstream valve. Classic downstream valves are particularly noted for their legendary safety and reliability. When in use, the downstream valve opens in the same direction as the incoming air flow. To close the valve and stop the air flow, a spring counteracts the force of the incoming air. Therefore, a certain inhalation effort is always required to overcome the spring tension and open the valve.

·Fixed VIVA (Venturi Initiated Vacuum Assist) flow vane. Fixed in the pre-tuned ideal position for safe and uncomplicated use.
