About Atomic Aquatics B2 Swivel Octopus, Yellow

Most manufacturers produce just an economy and a performance octopus model. Yet, even their high-end octopus cannot come close to matching the performance of the Atomic 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 B2 Octopus is easily the most comfortable and easy to use safe second ever designed with all-Titanium construction for corrosion protection and light weight. The B2 Octopus delivers all the patented Atomic features of the B2 primary model, including the comfort swivel as standard. The comfort swivel is the perfect design aspect for a safe second. The B2 safe second stage features critical metal components of the demand valve that are made of titanium and is completely corrosion proof. The B2 has a titanium demand valve body, lever and sealing orifice.

The Atomic B2 Octopus diaphragm is made from high quality silicone rubber. This pneumatically balanced poppet second stage has Atomics patented seat saving dynamic orifice which unlike most second stage orifices is a floating valve design which reduces wear on the second stage poppet seat when the regulator is not pressurized adding life to this important seal.

The B2 equipped with Atomics patented Automatic Flow Control (AFC). This unique diaphragm activated vain automatically controls the flow and Venturi effect of the second stage for optimum breathing resistance at all depths. The second stage does have a rapid adjustment knob for manual second stage de-tuning in rare special situations. The B2 Octopus has a has a bright yellow front cover for easy identification in an out-of-air-emergency and a 36" (91.4 cm) 3/8" threaded low-pressure (LP) hose. The regulator is also equipped with a dual silicone comfort fit mouthpiece with tear resistant bite tabs and weighs 13.15 oz (373 g) with the hose.
