Atomic Regulator Package: ST1 + Z2 Octopus + Gauges + BCD Hose

If you're looking for a premium scuba regulator setup that combines strong cold-water performance, refined breathing comfort and excellent long-term durability, this Atomic regulator package is a superb choice. It’s ideal for divers who want a high-performance Atomic regulator with a more environmentally considered stainless steel first stage, paired with a dependable precision-built octopus and flexible gauge options. You’re getting an advanced Atomic regulator, a matching backup regulator, your choice of gauge setup, and a Miflex Xtreme BCD hose to complete the package.

At the heart of the package is the Atomic ST1 Regulator. This high-performance regulator uses Atomic’s flow-through balanced piston first stage and pneumatically balanced second stage, but swaps titanium for solid 316 stainless steel in the first stage construction. The result is a regulator with corrosion resistance that comes very close to titanium, but at a more accessible price point. Stainless steel also offers excellent heat dissipation, helping improve cold-water performance and reliability as gas expands through the stages. Because it does not require chrome or nickel plating, it also offers a more environmentally considered construction and is fully recyclable at the end of its usable life. Like the rest of the Atomic range, the first stage features five low-pressure ports on a swivelling turret and two high-pressure ports on the main body for excellent hose routing flexibility. The second stage uses all-titanium internal construction, along with Atomic’s patented Seat Saving Orifice to prolong low-pressure seat life, Automatic Flow Control to help reduce the risk of free-flow, and a rapid adjustment knob for manual detuning when needed. The result is a regulator that feels smooth, capable and confidence-inspiring across a wide range of diving conditions.

Paired with it is the Atomic Z2 Octopus, designed and precision-built to perform as confidently as its primary model counterpart. Critical metal components in the demand valve are made from titanium or 316 stainless steel for excellent corrosion resistance, while the valve housing is machined from brass and plated with Atomic’s Zirconium finish for long-lasting durability. This gives you a dependable, high-quality backup regulator that performs exactly as expected when needed, while keeping the package practical and well balanced.

To complete the package, you can choose your preferred gauge setup and receive a Miflex Xtreme BCD Hose x 65cm. The Miflex SPG fitted with 80cm Carbon HD hose offers a lightweight and compact solution for divers who prefer to keep things simple, while the Miflex Double Console with Depth Gauge and SPG adds the reassurance of both pressure and depth readings in one compact and easy-to-read unit. The included Miflex Xtreme BCD hose uses a standard 3/8" fitting with a quick-release coupler, making it suitable for most BCDs, wings and drysuits using a standard QD connection. Its braided construction provides excellent flexibility and durability, helping complete a practical and dependable regulator package.
