ZEO + FDXi
. Its durable, chrome-plated marine brass valve provides a phenomenal breathing experience, improves cold-water performance, and helps circulate moisture from exhalation to prevent dry mouth. The breathing adjustment gives the diver a wide range of control to precisely adjust airflow throughout the dive.
The ZEO comes standard with an inline hose swivel, inhalation effort control, a dive/pre-dive switch with dynamic adjustment technology, and a super-comfortable orthodontic mouthpiece with an inline ball swivel at the hose connection to eliminate the binding that can cause jaw fatigue.
The FDX-i's cold-forged, overbalanced, diaphragm first stage is sealed against environmental influences. The inline design limits the pressure drop inherent in "L"-type first stage designs, making the FDX-i more efficient and lightweight due to its compact form factor.
ZEO Second Stage
The pneumatically balanced second stage automatically maintains a constant inhalation effort throughout the dive.
The diver-adjustable inhalation output allows the diver to control the desired airflow at any time.
The patented dynamic adjustment automatically maintains the inhalation effort throughout the dive.
Adjustable Venturi Switch (A.V.S.) for easy dive/pre-dive adjustment.
Inline ball swivel reduces jaw fatigue.
Orthodontic mouthpiece.
Paired with the FDX-i first stage.
