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.

Description:

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.
