The Atomic ST1 Regulator pairs Atomic’s smooth breathing performance with a precision-machined stainless steel first stage and premium titanium second-stage components.
Built from solid 316 stainless steel, the ST1 is designed for strength, corrosion resistance, and long-term durability while still delivering the refined breathing feel Atomic regulators are known for. The second stage includes Atomic’s Automatic Flow Control, a Rapid Adjustment Knob, and a Comfort Swivel hose to help reduce hose pull and improve comfort while diving.
A premium choice for divers who want a durable regulator for local diving, travel, and long-term ownership.
