This package pairs the Atomic Aquatics Z3 Regulator with its matching Z3 Octopus and an Atomic Aquatics Deluxe Padded Regulator Bag, so you get a complete first stage, second stage, backup second stage, and travel case in one setup. Pick the first stage connection that fits your tank valve and diving style: Yoke, Din, Yoke Sealed, or Din Sealed, with the sealed versions adding factory sealing to help keep silt and sand out of the mechanism.
The Z3 Regulator and Z3 Octopus share the same core engineering: a pneumatically balanced second stage with a high-flow case and lever, Atomic Aquatics’ patented Automatic Flow Control to reduce free-flow and cut down on manual tuning, a soft overmolded Rapid Adjustment Knob for detuning during surf entries or octo use, and Zirconium-plated brass with titanium components for corrosion resistance in saltwater. Both are Nitrox ready for non-dedicated EAN use with mixtures up to 40%. The Octopus adds a high-visibility yellow second-stage cover and a 36-inch straight yellow hose with no swivel, so a dive buddy can spot and grab it quickly if you need to share air.
The Atomic Aquatics Deluxe Padded Regulator Bag rounds out the package, with a fully padded interior roomy enough to hold the regulator, octopus, and gauges together, plus a reinforced carry handle and detachable shoulder strap for moving the whole setup between home and the dive site. It’s built to fit any Atomic regulator, making it a natural match for the Z3 gear it’s packaged with here.
