Product Information
The Atomic Aquatics Z3 Octopus is an alternate air source, or backup second stage, designed to let a diver share air with a buddy in an out-of-air situation. It pairs a high-visibility yellow second-stage cover with a 36-inch yellow low-pressure hose, making the octopus easy to locate and pass off underwater. This version uses a straight hose with no swivel and carries the same Zirconium-plated brass and titanium internal components found across the Z3 second stage for corrosion resistance and dependable performance.
Breathing performance comes from a pneumatically balanced second stage with a high-flow case and lever that deliver consistent airflow across depths and tank pressures. The patented Atomic Aquatics Automatic Flow Control (AFC) adjusts the Venturi effect automatically to help prevent free-flow while the octopus is not in use, and a soft overmolded Rapid Adjustment Knob allows manual detuning for octo use or surf entries. A Titanium Seat Saving Dynamic Orifice maintains factory tuning, an elliptical exhaust valve lowers exhalation effort at depth, and a dual-silicone comfort-fit mouthpiece with tear-resistant bite tabs adds comfort and durability. The Z3 Octopus is nitrox ready for non-dedicated EAN use with mixtures up to 40 percent.

Frequently Asked Questions
How often does a scuba regulator need servicing?
Follow the interval in your regulator's manual, since manufacturers commonly specify an annual inspection or a set number of dives and many warranties depend on it. A regulator is life-support equipment, so service belongs with a factory-trained technician rather than being attempted at home. Have it looked at sooner than scheduled if you notice increased breathing effort, free-flow, bubbles, or water in the second stage.
How do I rinse and care for a regulator after diving?
Make sure the dust cap is dry and firmly seated over the first-stage inlet before the regulator goes anywhere near water, because water inside the first stage is the leading cause of internal corrosion. Rinse in fresh water without pressing the purge button, since purging while depressurized can draw water back into the second stage. Shake out the water and hang it to dry with the hoses in wide, gentle loops rather than tight bends.
Can I fly with a scuba regulator?
Regulators travel well and are usually best carried in hand luggage where they will not be crushed or lost. A regulator holds no gas of its own, so there is nothing inherently problematic about it on an aircraft, though the airline and security screeners always have the final say. Pack it dry with the dust cap in place, in a padded regulator bag or wrapped in soft gear.
Can I use my regulator with nitrox?
Many modern regulators are supplied as suitable for nitrox mixes up to 40 percent oxygen, which is the widely used recreational industry standard, while anything above that requires dedicated oxygen-clean equipment and procedures. Confirm what your specific regulator's manual states, and follow your nitrox training and your fill station's requirements. Never assume a regulator is oxygen-service clean simply because it looks clean or is new.
What is the difference between DIN and yoke regulators?
A yoke (A-clamp) fitting clamps over the tank valve and is the most common connection across much of the recreational world, while a DIN fitting screws into the valve and is standard in much of Europe and in technical diving. DIN captures the o-ring inside the threads, which many divers consider more secure, but yoke is often what rental cylinders provide. Adapters exist in both directions, so check what is used where you dive before deciding.
What is the octopus regulator for?
The octopus is your backup second stage, carried so you can share air with a buddy who is out of gas, or breathe from it yourself if your primary fails or free-flows. It is normally on a longer, brightly colored hose so it is easy to find and hand over under stress. Secure it in the triangle between your chin and the bottom of your rib cage so it is instantly accessible and not dragging through sand or coral.
How should I store a regulator between dive trips?
Store it fully dry, out of sunlight, with the dust cap in place and the hoses in wide loops rather than tightly coiled. Avoid hanging it by the second stages for long periods, which stresses the hose fittings; laying it flat in a padded bag or hanging it by the first stage is kinder. If it has sat unused for a long stretch, have it checked before your next trip rather than assuming it is ready to dive.
