Overview
Our most popular model with the perfect combination of comfort, performance and style. The B2 has a chrome-plated brass first stage with a swiveling 5-port cap. The second stage houses lightweight titanium components and is also fitted with our patented Atomic Aquatics PVD coated brass comfort swivel hose. Environmental sealing is optional for this system.
Why Brass and 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 a close alternative to the all-Titanium T2. The signature Atomic breathing performance is nearly identical. The B2 is ergnomically designed to be the world's most comfortable second stage just like the T2. The key dfference is the chrome-plated Brass body of the B2 first stage, whcih is more economical without sacrificing performance. That's why the B2 has garnered more award from independent tests and reviews than any other regulator on the market.
