Atomic ST1 Regulator + Atomic Octo + Regulator Bag Package

This package pairs the Atomic Aquatics ST1 Regulator with the Atomic Aquatics Z3 Octopus and the Atomic Aquatics Deluxe Padded Regulator Bag, giving you a complete first stage, backup second stage, and travel case from the same builder in one order. Pick the first stage connection that fits your tank valve when you order: Yoke Sealed or Din Sealed.

The ST1's first stage is machined from solid 316 stainless steel and built around an Atomic Jet Seat high-flow piston design for smooth breathing, with a freeze-protected, factory-sealed first stage that keeps silt and sand out. It's nitrox ready for mixtures up to 40% and offers 2 fixed HP ports plus 5 LP ports on a swivel cap so you can route hoses the way your setup calls for. The Z3 Octopus serves as your buddy's backup air source, with a high-visibility yellow second-stage cover and a straight 36-inch yellow low-pressure hose (no swivel) that's easy to spot and hand off underwater. Its pneumatically balanced second stage and patented Automatic Flow Control work to prevent free-flow when the octopus isn't in use, and it's also nitrox ready to 40% for non-dedicated EAN use.

Once you're done diving, the Deluxe Padded Regulator Bag keeps the regulator, octopus, and gauges together and protected, with a fully padded interior, a reinforced carry handle, and a detachable shoulder strap for carrying it however you like between the car and the dive site.
