Your first step into planned CCR decompression, trained personally by a RAID CCR Instructor Trainer & Examiner
Instant access to your online learning, course preparation modules. Begin training immediately.
The RAID Deco Rebreather Diver course teaches you how to safely progress from no-decompression CCR diving into planned, controlled decompression. You’ll focus on short, efficient decompression profiles using Air or Nitrox without the added complexity of Trimix.
Planned Decompression: Learn to safely manage mandatory decompression stops and extend your bottom time at depth.
Optimal Efficiency: Train to conduct planned decompression dives with up to 10 minutes of total obligation, maximizing CCR gas efficiency and loop stability.
Unit-Specific Mastery: Receive precise, model-specific training on bailout planning, decompression protocols, and safe oxygen exposure management.
You’ll develop the skills, confidence, and discipline required to conduct planned decompression CCR dives to 40 metres / 130 feet. Focus areas include:
Loop PO₂ control and setpoint stability
Bailout readiness and gas switching
Emergency procedures
Decompression strategy and ascent planning
Unit-specific systems checks and protocols
Max Depth: 40 metres (130 feet)
Dive Type: Planned decompression
Gas Options: Air or Nitrox
Max Decompression Obligation: 10 minutes
Program Length: Online academics + minimum 8 in-water training sessions
Unit-Specific: Training delivered on your exact CCR model

To enrol, you must:
Be at least 18 years old
Hold RAID Deco 40 Diver or equivalent
Have 30 logged open circuit dives with 25 hours underwater
Have completed at least 6 dives to 30 metres
Hold RAID Sidemount Diver if training on a sidemount CCR
Your training is overseen personally by Stuart Girdler, RAID CCR Instructor Trainer & Examiner. Stuart ensures every student meets the rigorous RAID standards while applying real-world precision.
Training flows through a structured three-stage progression:
Before entering the water, you will complete all required online academic modules, quizzes, and the final exam. Topics include:
Decompression theory & bailout planning
Loop PO₂ management
Emergency staging procedures
Decompression tables & calculations
Gas planning & oxygen exposure limits
CCR unit-specific configuration & checks
You will complete a minimum of one confined-water session of at least 60 minutes.
A second session may be added based on diver readiness or instructor discretion.
Loop control and stability
Unit checks and pre-dive protocols
Buoyancy and trim on the loop
Emergency bailout drills
Valve manipulation (if applicable)
Stage handling (if doing Limited Trimix)
Open-water training develops full CCR decompression competence under direct instructor supervision.
Minimum 6 open-water dives
Minimum 360 min underwater
At least two dives to 35m / 115ft
Maximum deco obligation: 10 mins
Maximum setpoint (loop PO₂): 1.3 bar
Instant access to your online learning, course preparation modules. Begin training immediately.

Program Type: Decompression
Max Depth: 40 meters (130 feet)
Loop PO2 (Setpoint): Maximum planned PO2 shall not exceed 1.3 bar
Gases: Air & Nitrox
Skill Focus: General CCR skills and Unit-Specific protocols.
Certification: Valid for diving and maintaining a specific CCR unit type.
Unit Used: Training conducted on your own CCR model
Supervision Ratio: Maximum 3:1 student-to-instructor
Your CCR training is personally delivered by Stuart Girdler, a RAID CCR Trainer & Examiner with extensive multi-unit experience.
Stuart’s teaching philosophy prioritizes unit-specific competence, bailout mastery, and real-world preparedness, ensuring you leave this course confident, capable, and ready to dive safely within the full 40M limits of your rebreather.
Unit-Specific Competence: Stuart ensures you master the specific configuration and protocols of your rebreather unit, which is mandatory for certification.
Bailout Preparedness: Training requires carrying one bailout cylinder with sufficient capacity for a safe bailout from max depth based on a conservative 50 litre / 2 cubic feet per minute SAC rate.
Focused Supervision: Training is conducted under direct supervision with a strict maximum ratio of 3 students per Instructor, maximizing safety and learning efficiency.
