Beautifully machined from a special grade of solid 316 Stainless Steel, the Atomic ST1 is the world’s first “Green” regulator. The ST1 has the same renowned ergonomics and easy breathing that's designed into all Atomic Aquatics regulators. Stainless steel has twice the strength of brass and is nearly as corrosion-resistant as Titanium. Yet the requiRed resources, energy costs and environmental effects of manufacturing stainless steel give it a distinct ecological advantage over other metals.
