Atomic Aquatics B2 Titanium Octopus
The Titan pairs a balanced diaphragm first stage with a compact second stage for straightforward warm-water diving. Its Comfo-Bite mouthpiece and accessible Venturi control make it an approachable choice for a first personal regulator or a practical recreational setup.
Features and benefits

- Automatic Flow Control. The regulator adjusts flow characteristics as depth changes, with the rapid adjustment knob available for manual tuning.
- Titanium valve components. Titanium construction helps resist corrosion in the second-stage mechanism.
- Comfort Swivel. The swivel connection gives the hose room to move when the alternate air source is being used.
- Long alternate-air hose. The 91 cm hose provides room for the listed alternate-air configuration.
- Manual adjustment. The Rapid Adjustment Knob gives you a handling adjustment alongside Automatic Flow Control.

Atomic Aquatics B2 Titanium Scuba Diving Octopus Regulator
- When an alternate air source is needed, breathing performance and reliability matter. The Atomic Aquatics B2 Titanium Octopus Regulator is a premium safe second engineered to deliver the same smooth, natural breathing performance as the B2 primary second stage.
- Unlike basic octopus regulators designed only for occasional emergency use, the B2 Octo is effectively a high-visibility version of the acclaimed Atomic Aquatics B2 second stage. Its titanium construction provides exceptional strength, low weight and outstanding resistance to saltwater corrosion—helping ensure your backup regulator remains ready when it matters most.
- Atomic Aquatics’ patented Automatic Flow Control, Titanium Seat Saving Dynamic Orifice and pneumatically balanced design provide dependable airflow across changing depths and cylinder pressures. A black PVD-coated Comfort Swivel allows approximately 30 degrees of movement, reducing hose pull and making air sharing more comfortable.
- Finished with a highly visible neon-yellow purge cover and supplied with an extra-long 91 cm hose, the B2 Titanium Octopus is an outstanding safe second for divers who refuse to compromise on emergency breathing performance.
Additional specifications
- The B2 Octopus incorporates lightweight titanium components for exceptional strength and resistance to saltwater corrosion.
- The patented dynamic orifice moves away from the low-pressure seat when the regulator is not pressurised, helping prevent the seat from developing a permanent impression during storage.
- The black PVD-coated swivel provides approximately 30 degrees of movement between the hose and second stage.
- The B2 Octopus is supplied with a 36-inch hose for improved positioning and air sharing.
Pneumatically Balanced Second Stage
- Its balanced valve and high-flow internal design provide consistent performance across varying depths and cylinder pressures.
Why Choose the Atomic Aquatics B2 Titanium Octopus?
- A safe second should inspire the same confidence as your primary regulator. The Atomic Aquatics B2 Octo combines primary-quality airflow, corrosion-resistant titanium construction, excellent hose flexibility and unmistakable visibility in one premium alternate air source.
