Nautilus Second Stage Balanced Adjustable Technical Regulator – Engineered for Depth. Tuned for Precision.

The Nautilus Second Stage Balanced Adjustable Technical Regulator is purpose-built for demanding divers who explore deeper, stay longer, and expect total control over their breathing performance. Whether you're running stage bottles, diving in overhead environments, or building a fully redundant technical rig, this second stage is tuned to deliver uncompromising precision in the most challenging conditions.

At the core is a balanced valve system that ensures consistent, effortless airflow—regardless of tank pressure or depth. The adjustable inhalation knob gives you complete control over breathing resistance, while the venturi switch allows you to toggle between dive and pre-dive modes to prevent free-flow and optimise delivery when it matters most.

Housed in a rugged, compact body designed for minimal drag and superior trim placement, this second stage is ideal for sidemount, backmount, or stage applications.

Key Features:

Balanced Valve Mechanism – Ensures consistent breathing effort at any depth or cylinder pressure

Inhalation Adjustment Knob – Fine-tune your breathing resistance for precise control during critical dives

Venturi Control Lever – Reduces free-flow at the surface and boosts performance underwater

Technical-Grade Construction – Lightweight yet durable body for long-term use in challenging environments

Streamlined Profile – Designed for optimal hose routing and trim, ideal for technical configurations

Silicone Mouthpiece – Comfortable, secure fit for long-duration dives

The Nautilus Technical Second Stage is the perfect choice for divers who push limits, plan for redundancy, and expect precision performance every time.
