The RAID Normoxic Trimix Rebreather Diver course is an advanced technical diving program that trains divers to safely and confidently dive up to a depth of 60 meters (200 feet). As a normoxic trimix rebreather course, it requires a diluent that contains 18% oxygen, making it a highly specialised program that demands a high level of experience from divers.

In addition to diving expertise, physical fitness is also essential for this course since dives at this level require a considerable equipment package. Divers will need at least two bailout cylinders, and in some circumstances, three may be required. The equipment package also includes a rebreather, which allows the diver to recycle the breathing gas and reduces the amount of decompression required during ascent.

To enroll in the RAID Normoxic Trimix Rebreather Diver course, a diver must first have completed the RAID Deco Rebreather Diver course, as well as have significant experience in technical diving. The program covers advanced diving skills, including gas planning, dive planning, and decompression planning.

Upon successful completion of the course, divers will be certified to dive to depths of up to 60 meters using normoxic trimix diluent and rebreather technology. The RAID Normoxic Trimix Rebreather Diver certification is a significant accomplishment and is recognised worldwide as an indication of advanced technical diving skills.
