Atomic Aquatics B2 Octopus

About the Atomic Aquatics B2 Octopus

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.

Connected to a pressure sensitive diaphragm, the airfoil inside the mouthpiece, automatically repositions to regulate the venturi effect. At the surface, turbulent flow, then at depth, optimized for breathing comfort. With no dials to turn nor buttons to push, the patented, Automatic Flow Control, is the reason Atomic Regulators breathe with a comfortable, natural feeling at any depth.
