Part: 11.620.000 Item IncludesScubapro S620 Ti Regulator - Second Stage - LP Hose - MFG Lifetime Limited Warranty DescriptionThe new S620 Ti embraces the best features of Scubapro's renowned S600 in an upgraded, state-of-the-art design. Smaller and lighter than the S600 but using the same-sized diaphragm, the S620 Ti delivers excellent performance; work of breathing has been reduced by 37% over the S600, providing effortless airflow under all dive conditions. The full titanium inlet tube is ultra-light, the large purge button improves water circulation, and the new exhaust tee increases performance while directing bubbles out of the field of view. In all water temperatures, in all dive conditions, this new regulator system is a winner. Because of the S620's versatility, it can meet the diver's needs as frequently as the diver changes dive sites. The S620 valve housing is constructed from lightweight titanium. The S620 has a linear air-balancing valve, and a top-notch air-balancing system. This regulator's air-balanced linear-flow valve allows the diver to use less energy while breathing underwater; it makes breathing during a dive as simple as well, breathing in and out! The S620 air balanced high performance second stage, is Scubapro's performer. Rugged reinforced techno polymer case and front cover with stainless steel frame looks good plus is able to withstand years of aggressive diving. Regulator has a diver adjustable inhalation control that enables personal adjustment of breathing effort. Diver adjustable Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive control switch and extra high flow exhaust valve account for easy inhale & exhale. 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. The regulator comes equipped with a super comfort high-flow (HF) mouthpiece for smooth air delivery.FeaturesScubapro S620 Ti Regulator, Second Stage:Scubapro's Top PerformerEmbraces Best of Scubapro's Renowned S600Upgraded, State-of-the-Art DesignSmaller and Lighter than S600Unparalleled Breathing PerformanceWork of Breathing Reduced by 37% Over the S600Effortless Airflow Under All Dive ConditionsLinear Air-Balancing ValveTop-Notch Air-Balancing SystemDiver Adjustable Inhalation Effort for Personalized Breathing ControlVenturi Initiated Vacuum Assist (VIVA): Dive/Pre-Dive Control Switch Prevents Free Flow in Cold Water Decreased Inhalation ResistanceMaterials: Titanium & Techno-PolymersLarge Purge Button Improves Water CirculationExhaust Tee Increases Performance, Directing Bubbles from Field of ViewIn All Water Temperatures, Dive Conditions, New Regulator is a WinnerHigh Comfort Orthodontic MouthpieceSuper Flow Oversized Bore 3/8" Threaded LP HoseWeight: 6.3 oz (179g)SpecificationsAdjustable 2'nd StageYes, Adjustable Breathing Resistant's, Venturi Dive/Pre-Dive Switch2'nd Stage TypeAir Balanced ValveRegulator MaterialsTitanium & Techno-PolymersHose Thread3/8"Total Weight6.3 oz.
