Rating: one great reg!
Reviewer: Steven T.
I love this reg so much I bought my son one. I went to 115 feet with it and it was as easy to breathe as it was on the surface without having to make any adjustments.

Questions and Answers for Atomic Z2 Regulator:

  • Ben:

    What is the total weight of 1st and 2nd stages? Thanks

    Clarke  (Certified Scuba Instructor at

    Hello Ben, Thank you for your inquiry! The DYNAMIC Atomic Z2 Scuba Regulator (1st and 2nd Page), weight is 4.0 lbs. If you have any other questions or would like to place an order, please contact by calling 1-800-247-2822 or 949-221-9300 or e-mail us at:

  • Patrick:

    Hello, we are exclusively travel divers. I am looking at purchasing the Atomic Z2 reg and Z2 octo. Can you recommend a good travel BCD? I like the prices for the Avid CQR3 or the Mares Prestige 2 Plus, but am afraid they would be too bulky for travel. Or could I get away with one of those as a carry-on along with my regulator/octo? Thanks!

    Bob  (Certified Scuba Instructor at

    The Z2 will be a perfect choice of regulator for your travel needs. For information on alternate products please contact our instructors at

  • James:

    I am interested in the Z2 without the 2nd stage comfort swivel, but would like to get the optional 1st stage swivel? is this possible?

    Darrick  (Certified Scuba Instructor at

    Hello James, this regulator does not come with the 2nd stage swivel. Also if you are looking for the 1st stage swivel you would need to go with a different 1st stage:

  • Charles:

    Is the first stage sealed or not? The description mentions optional sealed first stage.

    Bob  (Certified Scuba Instructor at

    This version does not offer the sealed first stage.

Atomic Aquatics Z2/Z2x Regulator
Why Zirconium?
The “Z” designation is represented by the use of Zirconium as plating material for the precision machined Brass valve body. Atomic developed a Zirconium over Chrome over Brass plating process to deliver corrosion-resistance 3-4 times that of conventional chrome plating. The Z Series second stage lever, orifice and spring are Titanium.

Atomic Performance Plus Economy
Designing affordability doesn’t mean using shortcuts
The Z Series is our most compact and economical regulator system. But its rare combination of performance, ergonomics and materials is unmatched by competitors at any price. The Z Series gives divers the assurance of the same Limited Lifetime Warranty as all Atomic regulators.
First Stage:

First stage materials are chrome plated Brass and 316 Stainless Steel
Atomic Jet Seat high-flow piston first stage
Optional factory-sealed first stage to prevent outside contamination such as silt and sand
Nitrox ready for mixtures up to 40%
First stage ports available in 2 HP fixed / 7 LP on fixed cap

Second Stage:
Second stage components are made of precision machined Brass with Zirconium plating and Titanium
Z2x has a Brass Atomic Comfort Swivel
Patented Atomic Seat Saving Orifice (Titanium)
Patented Atomic Automatic Flow Control (AFC)
Rapid adjustment knob for manual second stage de-tuning in special situations
A new high-flow second stage case that significantly lowers breathing effort at any depth from shallow water to beyond the limits
Dual material second stage cover enables entire front to be used for purge
Dual silicone comfort fit mouthpiece with tear-resistant bite tabs
2 year/300 dive service interval
Limited Lifetime Warranty – not contingent on proof of service

Here are some important answers to frequent questions regarding Atomic regulators...

What is Natural Breathing?

Atomic Aquatics has achieved what no other manufacturer has in a high-performance regulator – Natural Breathing. All Atomic regulators breathe with a natural and controlled air delivery sensation at any depth or breathing rate. Inhalation on the surface will feel the same as it does during your deepest dive. This is in part due to the AFC (Automatic Flow Control) employed in our second stages. This patented innovation is a simple device that adjusts the airflow automatically to compensate for the effects of depth. Atomic Aquatics regulators are the smoothest breathing regulators available...period.

What are the diving benefits of Titanium?

First, it is unbelievably lightweight which reduces stress during your dive and makes it a perfect travel regulator. Second, Titanium has no equal for corrosion resistance which means more safety, reliability and repeatable performance. And finally, its beautiful appearance stands apart from any other regulator.

Unparalleled light weight means less stress

In our mission to invigorate the diving experience, the first priority is on reducing stress – travel stress, gearing-up stress, jaw-clinch stress. The best way is to use the lightest material possible. But light weight must never compromise strength or durability. Titanium is the perfect solution. When you hold a Titanium Atomic regulator in your hand, you immediately realize the difference from other regulators. That means less stress for you from packing your gear bag, to donning, to even the final minutes of a long dive.

Atomic Z2/Z2X Regulator


At first glance the Atomic Z2 and Z2x 1st Stage looks similar to one of several similar first stages on the market the past few years. It offers 2 high pressure ports and 7 low pressure ports offering a wide range of possibilities when it comes to the comfortable set up of your gear. This is where the similarities end. The Z2/Z2x first stage uses a different combination of materials in its construction all aimed at a offering the diver the highest performance in all uses and the lowest maintenance possible. Atomic utilizes a patented plating process of Zirconium over Chrome over Brass that offers corrosion resistance superior to any other regulator on the market. The process is also stronger than the normal plating process used by most manufacturers which will lengthen the regulators potential lifespan by resisting nicks and scratches that can often lead to flaking of the plating on other regulators. Not too shabby for an economical choice.

Internally this first stage delivers consistent air to the diver with a balanced flow-through piston that will offer the same intermediate pressure with each breath at the deepest depths or lowest tank pressures of your dive. The high pressure piston uses a seal system that is self lubricating that is designed to minimize the friction in this critical part and reduce wear and tear and in turn maintenance costs for the regulators owner.

And as if all of this technology and innovation in the Atomic 1st Stages wasn’t enough, their 2nd Stages are packed with one feature after the next all geared towards ease of breathing, longevity of the piece of equipment and low maintenance. The Z2x second stage uses an adjustable, pneumatically balanced poppet incorporated into a portion of the regulator that many manufacturers are looking for ways to cut corners and reduce costs in materials. Here, Atomic leads the way by using Titanium and Kevlar in key common parts. For most manufacturers that would be enough ammunition to light up the advertising and begin singing of their praises from the local mountain tops, but not with Atomic. They pressed on with redesigning two other important pieces in the 2nd stage that turned out to be so successful they were awarded patents for their efforts! The Seat Saving Dynamic Orifice was designed to reduce wear and tear on the low pressure seat and in turn increase the high performance of the second stage for the diver by making sure the orifice only comes into contact with the low pressure seat when the regulator is pressurized. The other innovation is their Automatic Flow Control. Most every manufacturer of regulators offer some sort of a venturi switch in their second stages designed to reduce breathing resistance and help with the opening of the valve that delivers air to the diver when they inhale. At Atomic they’ve perfected this into a pressure sensing, self-adjusting device that regulates the delivery of the diver’s air with every breath adjusting for increased pressure the deeper the diver descends. No more switches or dials to get that perfect breath of air! One last feature that the Z2x offers is the patented comfort swivel hose that allows for 30 degrees of rotation without kinking your hose.

A purchase of either the Z2 or Z2x it is fairly certain you’ll have a regulator built to last forever offering the performance of choices costing twice what you paid. This regulator is destined to be a “can’t miss” for years to come
