Detailed Description

Designed specifically for use as a deco regulator, the Dive Rite O2 Regulator offers clean and efficient gas delivery in shallow decompression profiles. The first stage features an unbalanced piston design for simplicity and reliability, while the second stage provides balanced downstream performance with an adjustment knob to tailor breathing effort.

This oxygen regulator is not intended for use as a travel or stage regulator and is not to be used below 50 feet (15 meters). It is optimized exclusively for use with deco gases like 50% or 100% oxygen during the final stages of a dive.

Its small profile makes it perfect for clipping off to a stage rig or stowing neatly with your decompression gas. Color-coded with a green hose, it’s immediately identifiable during critical gas switches. Whether you’re completing advanced nitrox dives or full trimix decompression schedules, this dedicated O₂ regulator simplifies your rig and supports safe ascent protocols.
