All Freedom Scuba Reg sets with Octo will come with a free SPG and HP hose with your purchase. We will also put it together and tune it for free for you upon request. 

These are not factory sealed but can be sealed by an Atomic Reg tech with ease.

Why Brass & Titanium? Even though the use of multi-layer chrome plated Brass for the body of the first stage is a more conventional material choice... the performance of the B2 is truly superior to any other rival

Atomic designed our signature breathing performance into the B2 to give a diver the perfect combination of comfort, style and value. The main design difference? The total weight of the B2 is only 9 ounces more than the T3.

The Most Awarded Atomic Regulator Virtually identical performance as the T3 with a Brass First Stage The B2 gives divers an close alternative to the all-Titanium T3. The signature Atomic breathing performance is nearly identical. The B2 is ergonomically designed to be the world’s most comfortable second stage just like the T3. The key difference is the chrome-plated Brass body of the B2 first stage, which is more economical without sacrificing performance. That’s why the B2 has garnered more awards from independent tests and reviews than any other regulator on the market.

Why A Family Of Octos? Most manufacturers produce just an “economy” and a “performance” octopus model

Yet, even their high-end octo cannot come close to matching the performance of the Atomic family of safe seconds. Each Atomic octopus is designed and precision-built to perform as perfectly as its primary model counterpart. So when you need it, you know exactly what to expect.

THE ECONOMY OF ZIRCONIUM. THE ELEGANCE OF ATOMIC

At Atomic Aquatics, they place the same priority on performance and emphasis on engineering for every product. They design our Safe Seconds to perform at the highest level for every budget level. Atomic engineers developed a unique 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, delivering natural easy breathing – the signature of all Atomic Regulators.

Cloning Can Be A Good Thing An Atomic octopus reduces stress in emergency situations. In an emergency, why would you or your buddy breathe from an inferior regulator? An octopus should breathe easy. All Atomic second stage primary models are available as dedicated safe seconds with high visibility yellow covers and an extra-long 36" hose.

Z2 Octo The Z2 safe second stage features critical metal components of the demand valve are made of Titanium or 316 Stainless Steel and completely corrosion proof. The demand valve housing is machined of brass and plated with an exotic Zirconium plating that exponentially outlasts conventional chrome plating.

PATENTED ATOMIC FEATURES ADD TO THE PERFORMANCE

The Z2 OCTO incorporates the same patented Atomic features that make our primary Regulator models the best in diving. The Atomic AFC Automatic Flow Control and Titanium Seat Saving Dynamic Orifice are identical to the Z2 primary second stage. The Z2 OCTO just looks different with the high-visibility Neon Yellow cover and extra-long 36” hose.

Z2 OCTO FEATURES

A perfect complement to any Atomic regulator systems, the Z2 OCTO is an affordable Safe Second for any dive rig. Zirconium-plated Brass and Titanium metal components, make this OCTO a real workhorse.

Patented Atomic AFC – Automatic Flow Control with Rapid Adjustment Knob for manual detuning in special situations.

Patented Atomic Titanium Seat Saving Dynamic Orifice prevents wear of the low-pressure seat that extends the service interval and improves reliability.

Compact with a low profile exhaust deflector that fits easily into pockets.

Bright Neon Yellow flexible front cover for high visibility.

All Atomic Octopus models come with a standard extra-long 36” hose.
