Questions and Answers for Atomic Z3 Regulator:

  • Lilla:

    Im fairly new to the game and wonder if the price include all the hoses and the thing that separates them all.. my second stage is on my BCD, so I will not need a hose or second stage reg. Does this change the price, can you quote me on the 1st, 2nd and all the apparatus needed to make it complete. Does it come with a bag? Thanks Lilla.

    Arthur  (Certified Scuba Instructor at

    Hello Lilla, this Atomic Z3 Regulator comes with the first(the part on the tank) and second(your main regulator) stage and the hose connecting the two. You can upgrade it to include the atomic octo(your back up). and no it doesn't include a regulator bag. But it is eligible for free shipping.

  • Lilla:

    Thanks Arthur, so can you please give me the cost of just the first stage and regulator, as I have the second stage already integrated in my BCD. Thanks. Lilla.

  • John:

    Do I have to purchase an Atomic Octo/Spare or does the Z3 allow you to utilize other manufacturers Octos? I was thinking of using my current Octo (Aqua Lung) with it since this one rarely has been utilized, is in good order, and is only 1.5 years old.

    Kevin  (Certified Scuba Instructor at

    You can use a different manufacturer''s octo with the Z3 without a problem.

  • Ken:

    Can I change the regulator hose to a flexible hose? If so, is it a specialty change out or can you use a standard wrench?

    Chance  (Certified Scuba Instructor at

    Yes, you can purchase a flex hose separate. It is a simple as turning a wrench, but I would recommend taking it to a service technician for installation or we can install it for you here.

The Best Regulators Ever Designed

How materials and passion come together for perfect dives
At Atomic we sometimes feel like a symphony conductor – bringing together exotic materials, groundbreaking design, and superior manufacturing in perfect harmony. The result is our signature line of regulators that are widely considered the finest ever designed by independent reviewers and passionate divers across the globe. So how do we do it? There are no real secrets here...we are an open book and want you to see for yourself why Atomic regulators are the finest ever to submerge. No other company has the courage or determination to put all these elements together as we have. Take a look...

“Compromise” Is A Word We Don’t Know
Titanium is uncompromising...and nobody uses it like Atomic
There is simply no better material for the ocean environment than Titanium. A Titanium regulator part could actually survive beneath the sea for centuries without a trace of corrosion. Atomic heavily invested in the people, machinery and time needed to develop new fabrication techniques at our own USA R&D facilities. If you see other companies claiming “Titanium” regulators, closely investigate. They do not employ these materials as thoroughly or effectively as Atomic Aquatics. You will see on the following pages exactly which parts in every Atomic regulator are machined from Titanium and why they excel.

Atomic wins the regulator trifecta:
natural performance – low maintenance – stunning appearance

The ultimate test of any regulator is how it breathes. Atomic Aquatics designed “natural breathing” into every regulator model, regardless of materials or price. Just because we design a regulator using different materials to achieve a lower price-point, does not mean we compromise on performance. Every review or independent test an Atomic regulator has been involved in has concluded with a top ranking. Superior performance is inherent in every Atomic model at any dive depth or breathing rate. Our use of corrosion-resistant materials also results in much lower maintenance requirements for divers. We stand behind this claim with our 2-Year/300 Dive Warranty (see details on pages 10-11). Finally, beautiful appearance is an Atomic imperative. Every time you pull your Atomic reg from its bag, you will be proud of its technologically-superb appearance...and other divers may take an envious glance. Our plating processes and machine-turned finishes produce an immediately recognizable distinction.
