"Score: 20 out of a possible 20" -Scuba Lab
"Atomic Aquatic's B2 breathes effortlessly on the simulator, regardless of RMV or depth. But this isn't just a laboratory reg. The B2 earned the highest total score for in-water performance of any reg in any price class. It breathes easily in all positions and is the only reg to earn an excellent score for dryness.

Hi, I am going to be diving in the cold waters of NE and was wandering if the b2 is going to be a good choice for me? I am also going to do lots of wrecks diving with nixtox. Is this regulator better for me or you suggest a better one?
Why would / should I choose the B2 over the Z3? What am I getting in the B2 for the extra ~$200?
When I order the Atomic B2, how do I make sure I get the optional sealed first stage?
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.

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.
The B2 regulator is Atomics entry level offering priced to sell next to many of the lower end offering from other scuba manufacturers. At first glance the 1st Stage looks like one of several similar first stages on the market. It offers 2 high pressure ports on the body and 5 low pressure ports on a swivel cap giving the diver a wide range of possibilities when it comes to the comfortable set up of your gear. This is where the similarities end. The B2 First Stage is purposely designed to give nearly identical performance to that of the flagship (and far pricier) T2 but uses more traditional materials such as chrome plated brass in an effort to keep costs down. It is interesting to note that the B2 has actually won more awards from independent testing facilities than any other regulator on the market! Not too shabby for a so-called “entry level” 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. To top it all off, the B2 is nitrox ready up to 40% right out of the box!
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 B2 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 B2 offers is the patented comfort swivel hose that allows for 30 degrees of rotation without kinking your hose.
With the B2 regulator offering everything any diver could ever ask for from price to innovation and performance, there is no reason for any diver to choose anything else.
