Beautifully machined. Beautiful performance. And it keeps the oceans beautiful, too. As the first “Green” regulator ever designed, the ST1 is made of a special grade of 316 Stainless Steel that is 100% recyclable. The ST1 offers superior corrosion-resistance and does not require Chrome or Nickel-plating processes that create environmental concerns.
Environmentally conscious topside natural breathing at depth
The ST1 is another industry first from Atomic Aquatics. The first stage is beautifully machined from a special grade 316 Stainless Steel that is twice the strength of brass with corrosion-resistance approaching Titanium. The use of Stainless Steel means we are doing our part for clean air when divers are out of the water. The legendary Atomic design means divers also breathe easy at depth.
All this Stainless Steel durability weighs just 2.3 pounds (yoke version), making the ST1 an excellent travel companion.
