What is Rebreather Diving?

Rebreather diving is a type of scuba diving that uses a rebreather system, rather than traditional open-circuit scuba tanks, to recycle exhaled gas. In a rebreather, the exhaled air is captured and processed to remove carbon dioxide. The remaining oxygen is then mixed with a small amount of fresh gas to maintain an optimal breathing mix, and returned to the diver for inhalation. This process is more efficient than traditional scuba diving, which releases the exhaled air into the water.

Benefits of Rebreather Diving:

  1. Longer Dive Times: Because you’re recycling your air, you can often stay down longer without requiring a refill.
  2. Silent Diving: Unlike open-circuit diving, which releases bubbles, rebreather diving is virtually silent, allowing for closer encounters with marine life.
  3. Optimal Gas Mix: The rebreather can provide an optimised gas mix at varying depths, allowing for more efficient gas consumption and potentially safer decompression.
  4. Less Buoyancy Variation: Because you’re not expelling air into the water, your buoyancy levels are more consistent throughout the dive.
  5. Reduced Gas Consumption: For the same dive time and depth, you’ll generally use less gas than you would with open-circuit diving, which can be beneficial on extended or deep dives.

Frequently Asked Questions

The course is designed for certified divers who want to explore new diving technologies. Participants should be at least 18 years old.

A rebreather is a type of scuba equipment that recycles the gas you breathe by removing the carbon dioxide and adding used oxygen, which allows for longer dives and more interaction with wildlife.

The course takes 1/2 day, which includes both the classroom and pool session.

The Introductory Rebreather Experience is a try-dive, not a certification course. If you’re interested in becoming a certified rebreather diver, you can enroll in a Rebreather Diver course after completing this introductory experience.

Rebreather diving is quieter than open-circuit diving, which can lead to more wildlife encounters. It also allows for longer dive times and uses gas more efficiently.
