Product Overview

The Atomic Aquatics ST1 pairs a first stage machined from solid 316 stainless steel with a pneumatically balanced second stage featuring titanium metal components.

Its sealed first stage offers corrosion resistance and a swivelling turret for flexible hose routing. The stainless steel Comfort Swivel allows the hose to move as you turn your head, helping reduce pulling at the mouthpiece.

Automatic Flow Control manages Venturi assistance as depth changes, with a Rapid Adjustment Knob for manual adjustment when needed.
