Scuba Regulators – 1st and 2nd Stage Sets

Discover our collection of scuba regulators including complete 1st and 2nd stage sets designed for optimal performance, safety, and comfort underwater. These high-quality regulators provide smooth airflow, reliable performance in all diving conditions, and compatibility with various tanks and dive setups. Perfect for recreational, technical, and travel divers, our regulator sets ensure effortless breathing and enhanced dive control.

Why Choose a 1st and 2nd Stage Regulator Set?

  • Reliable airflow: Consistent breathing performance at any depth and tank pressure.
  • Durability: High-quality materials like chrome-plated brass and reinforced polymers.
  • Corrosion resistance: Suitable for saltwater and freshwater diving environments.
  • Easy maintenance: Modular design allows simple servicing and part replacement.
  • Compatibility: Works with multiple BCDs and tanks for maximum versatility.

Key Features to Consider

  • 1st stage: balanced or unbalanced, diaphragm or piston design
  • 2nd stage: adjustable venturi, purge button, and ergonomic mouthpiece
  • High-flow ports for octopus and inflator hose connection
  • Environmental sealing for cold-water diving
  • Breathing performance tested across different depths

Who They’re Best For

Recreational divers: Smooth, reliable regulators for everyday diving.
Technical divers: Durable and customizable regulators for cold-water and deep dives.
Travel divers: Lightweight, compact sets ideal for easy packing.
Beginner divers: User-friendly, easy-to-maintain sets for safe learning.

Buying Tips

  1. Determine diving environment: Cold-water divers may require environmentally sealed 1st stages.
  2. Check flow performance: Balanced regulators provide easier breathing at all tank pressures.
  3. Consider comfort: Ergonomic 2nd stage mouthpieces reduce jaw fatigue during long dives.
  4. Maintenance requirements: Choose sets with easy servicing and widely available replacement parts.
  5. Hose compatibility: Ensure the regulator works with your BCD inflator and octopus setup.

Maintenance & Care

  • Rinse thoroughly in fresh water after every saltwater dive.
  • Flush the regulator to remove sand, salt, and debris from the 1st and 2nd stages.
  • Store regulators in a cool, dry place away from direct sunlight.
  • Have professional servicing annually or as recommended by the manufacturer.
  • Inspect hoses and mouthpieces for cracks or wear before each dive.

Frequently Asked Questions

What is the difference between a 1st stage and a 2nd stage regulator?

The 1st stage attaches to the tank valve and reduces high-pressure air to an intermediate pressure. The 2nd stage delivers breathable air to the diver on demand, usually through a mouthpiece.

Do balanced regulators perform better than unbalanced ones?

Yes, balanced regulators provide consistent airflow at all tank pressures and depths, making breathing easier and more reliable.

Can I use the same regulator set for cold and warm water?

Standard regulators work in warm water, but cold-water diving may require environmentally sealed 1st stages to prevent freezing.

How often should regulators be serviced?

Manufacturers recommend professional servicing at least once a year or after 100 dives, whichever comes first, to ensure optimal performance and safety.

What features improve comfort during long dives?

Ergonomic mouthpieces, adjustable venturi, and light second stage design reduce jaw fatigue and improve breathing comfort for extended dives.
