What's in the box: First and Second Stage Regulators, Low Pressure Hose and Owner's Manual

The Sub Gear SG50 Regulator is a High Performance Balanced Diaphragm First Stage Regulator with Dry Chamber for all temperatures, including cold or murky water. The SG50 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. Bearing in mind that regulators generate temperatures as low as minus 22°F (-5.5°C) due to the incredibly fast moving air and the pressure drop involved, it is imperative that sensitive moving metal parts avoid contact with extremely cold water or debris. Therefore, diaphragm first stages have been the favored choice of cold-water divers and those working in contaminated or muddy water. The added Dry Chamber Secondary Diaphragm Membrane and Piston, communicate external ambient pressure changes to the internal valve mechanism. The total exclusion of water from the regulator's interior including the spring chamber means that no ice can form inside during cold water dives. 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 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. The First Stage has a balanced diaphragm to offer 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 SG50 has a Dive/Pre-Dive Switch to prevent unwanted Free-Flow on the surface and to provide Ease-of-Breathing at Depth. The SG50's Streamline Design, Minimal Weight, Spherical Hose Swivel and Orthodontic Silicone Mouthpiece mean Jaw Fatigue and Pain won't be a hindrance for you breathing from the second stage regulator. The Spherical Hose Swivel will also eliminate the Pulling-Effect" found on Regulators without a Swivel for added comfort while diving. 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 SG50 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 36.16 oz (1,025 g) without the Hose. The SG50 Regulator comes with an Owner's Manual and is covered by a 30 year limited warranty.
