This octopus offers an ideal balance of quality, comfort, and reliability. The SG10 regulator's downstream valve means you can dive breathing easily - both literally and figuratively. The SG10 has a Dive/Pre-Dive Switch to prevent unwanted Free-Flow on the surface and to provide Ease-of-Breathing at depth. The SG10'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. Regulator hose is equipped with standard 3/8" threaded end. The SG10 weighs 5.9 oz (167 g) w/o hose and comes with an Owner's Manual. The SG10 Regulator is covered by a 30 year limited warranty.
