Rebreather Diving

Rebreathers offer a unique and immersive diving experience that allows divers to observe sea life up close and explore underwater attractions in intimate detail. While rebreathers have been traditionally used by the most serious and committed divers, as technology improves and costs come down, they are becoming more accessible to a wider range of divers. However, rebreathers require exceptional commitment and dedication to proper training and procedure.

NAUI rebreather training is available through the following NAUI programs:

Semi-Closed Circuit Rebreather (SCR) Diver
The Semi-Closed Circuit Rebreather Diver course provides you with the training and knowledge necessary to understand the benefits and risks of using a semi-closed circuit rebreather (SCR) while breathing EANx mixtures of 32% to 80% oxygen. Upon successful completion of this course, divers will be considered competent to plan and execute unit specific SCR dives up to 100 fsw (30 msw).

Closed Circuit Rebreather (CCR) Diver
The NAUI Closed Circuit Rebreather course provides you with the training and experience necessary to understand the hazards and minimize the risks of using a closed circuit rebreather while breathing EANx with a constant oxygen partial pressure. Upon successful completion of the NAUI Closed Circuit Rebreather course, you are qualified to plan and execute unit-specific, air-diluent, no-decompression, closed circuit rebreather dives to depths not exceeding 100 fsw (30 msw).

Closed Circuit Rebreather Mixed Gas (CCRMG) Diver
The NAUI Closed Circuit Rebreather Mixed Gas Diver course provides you with the skills and knowledge needed to minimize the risks of utilizing helium-based or trimix breathing diluent gas mixtures for dives with rebreathers and constant PO2 requiring decompression. Upon successful completion of the NAUI Closed Circuit Rebreather Mixed Gas Diver course, you are qualified to plan and execute technical, constant PO2 dives on unit-specific CCRs that require decompression and utilize helium-based or Trimix breathing gas mixtures to depths not exceeding 200 fsw (61 msw).

Extreme Exposure Closed Circuit Rebreather Mixed Gas Diver
The NAUI Extreme Exposure Closed Circuit Rebreather Mixed Gas Diver course provides you with the skills and knowledge needed to minimize the risks of utilizing helium-based or trimix breathing diluent gas mixtures for dives with rebreathers and constant PO2 requiring decompression. At least four dives below 200 fsw (61 msw) are required during training, not to exceed 300 fsw (91 msw).

Mixed Gas Blender and Oxygen Service Technician
The NAUI mixed Gas Blender and Oxygen Service Technician course provides you with the skills and knowledge needed to safely handle high pressure gases, prepare oxygen enriched air and helium-based mixes, and prepare equipment for oxygen service.

Get Started

Minimum age for NAUI Technical training programs is 18 years of age. Additional training and experience requirements vary for each course. A qualified NAUI Instructor can evaluate your experience and answer questions about your readiness to pursue specific training.

Planning Ahead

NAUI technical divers can maintain or improve skills through a variety of NAUI programs including the suite of NAUI First Aid course, NAUI Nitrox Gas Blender and NAUI Mixed Gas Blender.
