Oceanic Zeo FDXi Regulator




The Oceanic Zeo FDXi regulator is a beautifully compact first and second stage. Connected with Oceanic's MaxFlex lightweight, braided hose for a higher burst pressure and improved UV protection. The second stage is also connected with a built in swivel to reduce stress on the jaw for a more comfortable dive.

The Zeo second stage has all of the features of a top of the line second stage and a lightweight design which makes it perfect for travel. The Zeo features a pneumatically balanced valve to improve airflow and increase your bottom time with a dynamic air flow adjustment that can be adjusted during the dive and automatically maintains inhalation effort throughout the dive. The Zeo also has a Pre-Dive Venturi adjustment to prevent freeflows on the surface. On the inside of the second stage Oceanic have used a metal barrel that acts as a heat-sync to improve cold water performance and a better breathing experience.

The FDXi first stage is an over-balanced diaphragm design that delivers the best performance no mater what the depth or air pressure. The FDXi is environmentally sealed to improve cold water performance and longevity by preventing foreign bodies from entering the first stage. It's in-line design improves airflow but minimising corners and turns which can slow air and ruin performance.
