Zeagle Onyx II Yoke Regulator

The Zeagle Onyx II Regulator is a high-performing, reliable diving gear that rivals many more expensive alternatives. Its innovative design allows direct airflow through the first stage, ensuring low turbulence and superior performance. The regulator's conical precision stainless steel high-pressure valve and advanced polymer seat offer increased reliability and durability while enhancing responsiveness and performance across all breathing rates. Manufactured in the USA under stringent quality controls, Zeagle's regulators are made to last.

The first stage regulator is crafted from black chrome plated marine brass with a balanced diaphragm design, which is inherently environmentally sealed. This design prevents water contaminants like salt, sand, and chlorine from entering the internal mechanism, thereby reducing corrosion and mineral deposits. As a result, the regulator's performance remains consistent and long-lasting.

Equipped with two high-pressure (HP) 7/16" threaded ports and five low-pressure (LP) 3/8" threaded ports, this first stage regulator allows for attachment of gauges and other accessories such as inflator hoses and octopus regulators. Its balanced diaphragm design, coupled with high-performance porting and environmental and dry seals, ensures years of reliable, corrosion-free service in cold water conditions.

The Onyx Second Stage is a lightweight, compact, and comfortable regulator featuring adjustable inhalation resistance controls, free-flow control, and an anodized aluminum heat sink with an anti-freezing feature. It's designed to resist free-flow on the surface while providing smooth, effortless breathing underwater. Made from flexible and rigid thermoplastics, elastomeric polymers, and silicone rubber, this pneumatically balanced downstream demand valve second stage regulator is durable and efficient. The complete set weighs 42.6 oz. (1,208 g) with a 30" (76 cm) hose and comes with a detailed owner's manual. It's Nitrox-ready up to 40% straight out of the box, making it perfect for all kinds of diving.
