Questions and Answers for Atomic B2 Regulator - 2nd Stage Only:


  • Randy:

    Why is this sold as second stage only? What about the first stage! .

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Randy, some manufacture sell these as stand alone items also. Some people like to have the same regulator as there primary.

Atomic Aquatics B2 Regulator
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 T2.

The Most Awarded Atomic Regulator
Virtually identical performance as the T2 with a Brass First Stage
The B2 gives divers an close alternative to the all-Titanium T2. 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 T2. 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.

All-Titanium second stage construction same as Atomic T2
Patented Atomic Seat Saving Orifice
Patented Atomic Automatic Flow Control (AFC)
Rapid adjustment knob for manual second stage de-tuning in special situations

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.
