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 FDXi. The cold forged, over-balanced diaphragm FDXi is environmentally sealed and comes with our patented Dry Valve Technology (DVT). It's in-line design limits the pressure loss inherent in "L" type first stage designs making the FDXi more efficient and lighter due to it's compact form.
The ZEO/FDXi 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
paired with the FDXi first stage
First Stage FDXi
The FDXi 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.
