Description Based on the renowned D400, this one of a kind second stage includes a unique valve design and offers x-tra performance. The X650 represents the X-Series that is considered to be the best performing second stage of the SCUBAPRO line due to unparalleled ease of breathing and x-traordinary air flow characteristics.
X-650 SECOND STAGE
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.
Balanced coaxial flow valve. This unique design directs the airflow straight into the diver�s mouth and prevents any loss in performance. The airflow is effortless and instant on demand independent of the tank pressure and in the most controlled manner.
20% less exhalation effort than the other second stages. A new and wider exhaust valve, minimising exhalation effort more than any other second stage.
Diver adjustable inhalation effort, to quickly increase or decrease inhalation effort and fine-tune the second stage to any diving condition including cold water environments. Dive/pre-dive control switch.
Diver adjustable VIVA (Venturi Intiated Vacuum Assist) 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.
Sturdy super-flow hose with Kevlar lining for extra durability and flawless air delivery.
High comfort 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.
Super high flow exhaust valve.
Designed for comfort. Big soft purge and oversized controls. Easy to find purge and oversized control functions facilitate handling even with thick cold water gloves. X-traordinary valve positioning and compact size. Less jaw fatigue due to streamlined shape and lighter weight.
For extreme conditions and environments due to its precision molded, light weight components and anti-freeze materials resulting in high corrosion resistance and x-cellent cold water performance.
