Oceanic Zeo + FDXi Dive Regulator


The pneumatically-balanced ZEO is a remarkable feat of engineering, showcasing exceptional precision, durability, and comfort. The durable chrome-plated marine brass metal valve ensures a superior breathing experience, enhances cold-water performance, and effectively recirculates moisture from exhalation to prevent dry mouth. The breathing adjustment allows the diver to have precise control over the airflow during the dive.

The ZEO includes an in-line hose swivel, inhalation effort control, dynamic adjustment technology dive/pre-dive switch, and a comfortable orthodontic mouthpiece with an inline ball swivel on the hose connection to prevent jaw fatigue from binding.

At the heart of this remarkable system lies the Oceanic Zeo, a second-stage regulator that has been meticulously designed to deliver unparalleled performance, even in the most demanding diving conditions. Featuring a durable, chrome-plated marine brass valve, the Zeo not only boasts exceptional cold-water capabilities but also actively helps recirculate the moisture from your exhalation, effectively eliminating the dreaded "dry mouth" phenomenon that can plague divers.

Diver Adjustable AirFlow: One of the Zeo's standout features is its pneumatic balancing system, which automatically maintains a consistent inhalation effort throughout the entirety of your dive. But the true genius lies in the diver-adjustable inhalation effort controls, allowing you to precisely tailor the airflow to your personal preferences.

More Innovative Elements: The regulator comes equipped with a patented Dynamic Adjustment technology, which automatically maintains your desired inhalation effort, even as the depth and pressure fluctuate. Additionally, the Adjustable Venturi Switch (A.V.S.) enables simple and intuitive dive/pre-dive adjustments, while the inline ball swivel reduces jaw fatigue by eliminating the binding that can occur with traditional hose configurations.
