Aqua Lung Core Supreme — Balanced First Stage Regulator for Reliable Diving Performance

The Aqua Lung Core Supreme delivers high-end breathing performance and cold-water reliability in a mid-range regulator — making it a go-to choice for divers who demand solid performance without breaking the bank. Its balanced first-stage diaphragm and pneumatically balanced second stage ensure smooth, consistent airflow at any depth. 

???? Key Features & Why It Matters

Balanced Diaphragm First Stage — delivers stable, reliable breathing performance whether you’re 20 ft or 200 ft down.

Auto-Closure Device (ACD) — seals out corrosive water when the first stage is detached, protecting internal lubrication and ensuring safer performance when using enriched air mixes. 

Cold-Water Ready — Environmental Dry-Seal first stage + patented heat exchanger and lip-shielded second stage keep the regulator ice-free and dependable in chilly waters below 50 °F (10 °C). 

Optimized Hose & Port Layout — 4 medium-pressure (MP) and 2 high-pressure (HP) ports, arranged in a T-shape, allow clean hose routing and easier gear configuration.

Comfo-Bite™ Mouthpiece — soft, ergonomic mouthpiece reduces jaw fatigue on long dives.

Nitrox Ready & Serviceable — compatible with up to 40% O? out of the box, and shares parts with other Aqua Lung regulators for easier servicing and maintenance.
