"Designed for Depth. The pneumatically-balanced ZEO is an engineering marvel of precision, durability and comfort. Its durable chrome-plated marine brass metal valve delivers a phenomenal breathing experience, improves cold-water performance and helps recirculate moisture from exhalation to prevent dry mouth. The breathing adjustment gives the diver a wide range of control to precisely set airflow throughout the dive. The ZEO comes standard with an in-line hose swivel, inhalation effort control, dynamic adjustment technology dive/ pre-dive switch and a super comfortable orthodontic mouth piece featuring an inline ball swivel on the hose connection to eliminate the binding that can cause jaw fatigue. The new cold-forged, over-balanced diaphragm FDX-i first stage is environmentally sealed. The in-line design limits the pressure loss inherent in \"L\" type first stage designs making the FDX-i more efficient and lighter due to its compact form. Try telling an engineer that a design, any design, can't be made… better. In our case that challenge led directly to the ZEO. We started with the EOS, a legendary regulator known for it's comfort and breathing profile and ended up with the ZEO. Like it's predecessor the EOS, the ZEO is also a phenomenal breather allowing the diver extensive control over the air flow profile at any depth. It takes this design one step further however by incorporating a tough and corrosion resistant chrome plated marine brass valve that has better cold water performance and even a better breathing experience. The all metal valve encourages the condensation of water vapor from your exhalation on the valve housing. When you inhale that condensed water vapor circulates with the airflow and helps to reduce \"dry mouth\" and increase the overall level of comfort. The ZEO also comes with our patented Dynamic Adjustment technology, diver inhalation effort adjustment controls, dive/pre-dive switch, swivel and an super comfortable orthodontic mouth piece. The ZEO second stage comes paired with our new first stage FDX-i. The cold forged, over-balanced diaphragm FDX-i is environmentally sealed. It's in-line design limits the pressure loss inherent in \"L\" type first stage designs making the FDX-i more efficient and lighter due to it's compact form. The ZEO/FDX-i combination is everything you need for a sublime breathing experience at any depth and in any environment. From the balmy tropical waters of the caribbean to the extremes of cold water diving's best dive sites, the ZEO will perform with reliability, consistency and comfort and makes taking your favorite regulator literally anywhere, that much easier. Second Stage ZEO  Pneumatically balanced second stage automatically maintains consistent inhalation effort throughout dive Diver adjustable inhalation effort allows the diver to control a desired level of airflow at any time. Patented Dynamic Adjustment automatically maintains inhalation effort throughout the dive Adjustable Venturi Switch (A.V.S.) for simple dive/pre-dive adjustment Inline ball swivel reduces jaw fatigue Orthodontic mouthpiece Paired with the FDX-i first stage    First Stage FDX-i The FDX-i in-line design provides an improved flow rate, greatly reduced weight and more ergonomic port positioning for better hose routing when compared to the classic right angle first stages.  Precision Cold Forged Reduced weight Pneumatically balanced - consistent performance at any depth Environmentally Sealed diaphragm - cold water ready 4 Low Pressure and 2 High Pressure Ports Angled ports for ideal hose routing Improved flow rate over standard right angle first stages.    Specs 2nd stage     FEATURE &amp; FUNCTIONS   ZEO SECOND STAGE (METAL VALVE SYSTEM)     Valve Type   DEMAND     Adjustment(s)   KNOB / PRE-DIVE SWITCH     Balancing System   PNEUMATIC     Integrated Purge Button   YES     Mouthpiece   ORTHODONTIC W / TABS     Nitrox Compatibility   STANDARD TO 40%     Ambidextrous   NO     Integrated Switch   YES     Weight (without hose)   7.2 OUNCE     Dimensions (front profile)   2.3 INCH x 3 INCH (OVAL SHAPE)     Minimum Creaking Effort   DIVER ADJUSTABLE     Factory Set Inhalation Effort   0.0~2.5 IWC     Work of Breathing   0.86     First Stage   FDX-i       Specs 1st stage     FEATURES &amp; FUNCTIONS   FDX-i     Valve Type   BALANCED DIAPHRAGM     Primary Material   FORGED MARINE BRASS     Low Pressure Ports   4     High Pressure Ports   2     FIXED YOKE KNOB   YES     Nitrox Compatibility   STANDARD TO 40%     300 BAR DIN Fitting   OPTIONAL     Sealed Valve Design   YES     Environmental Protection   YES     Weight (Yoke)   21 OUNCES     Factory Set Intermediate Pressure   138-142 PSI     Pressure Drop   9 PSI    "
