The SG30 is top choice for the discerning diver. The Sub Gear SG30 Regulator is a High Performance Balanced Diaphragm First Stage Regulator. The SG30 First Stage Regulator is the perfect choice for the recreational diver who wants the advantage of a diaphragm first stage for use in temperate waters. The Balanced Diaphragm, Chrome Plated Marine Brass First Stage Regulator is inherently Environmentally Sealed. The benefit of this type of first stage design is that none of the delicate internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants can cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.
Sub Gear's diaphragm first stages feature balanced technology and are packed with features resulting in ultra fast flow to the second stage on demand and a fantastic overall performance. The SG30 first stage's streamline body offers you peace of mind with its smooth breathing mechanisms and maximum performance that does not diminish as your tank's air pressure changes. First-Stage Regulator is equipped with 2-High Pressure (HP) and 4-Low Pressure (LP) Ports, 2 of the LP Ports are High Flow Ports (HFP) that provide Superior Airflow to the Second Stage Regulators. The First Stage is NITROX Ready Up to 40% and is Cold Water Tested to Meet EN250 Requirements.
The Second Stage incorporates a Power-Flow Fail-Safe Downstream Demand Valve which is simple, yet efficient. The SG30 has a Dive/Pre-Dive Switch to prevent unwanted Free-Flow on the surface and to provide Ease-of-Breathing at Depth. The SG30's Streamline Design, Minimal Weight and Orthodontic Silicone Mouthpiece mean Jaw Fatigue and Pain won't be a hindrance for you breathing from the second stage regulator. The streamline shape also means the experience of gear drag is a thing of the past. Clearing the Regulator is made easy with the High-Flow Purge Valve and Exhaust.
To further Increase Breathing Performance the SG30 has an Adjustable Breathing Resistance Knob. By Turning the Knob Clockwise" the Breathing-Resistance-Increases which will Further-Reduce the chance of Free-Flow when Diving against a Current or when Entering the Water through Surf or Jumping-Off the back of a Boat. When the Knob-is-Turned Counterclockwise" the Breathing-Resistance-is-Decreased providing Exceptionally Easy Breathing when needed. Regulator hose is equipped with standard 3/8" threaded end. Complete regulator weighs 33.3 oz (945 g) without the Hose. The SG30 Regulator comes with an Owner's Manual and is covered by a 30 year limited warranty.
