Teach deep hypoxic trimix decompression diving with authority, control, and RAID-approved instructional oversight.
Begin your progression toward becoming a RAID Hypoxic Decompression Instructor.
The RAID Hypoxic Decompression Instructor rating represents the highest level of open-circuit decompression instruction within the RAID system. This qualification authorises you to teach and certify divers conducting deep hypoxic trimix decompression dives, where gas density management, oxygen exposure control, and long decompression obligations demand exceptional instructional precision.
As a Hypoxic Decompression Instructor, you are responsible for preparing divers for extreme depth environments while maintaining strict RAID safety, planning, and evaluation standards.
As a RAID Hypoxic Decompression Instructor, you are authorised to teach and certify:
RAID Hypoxic Decompression Diver programs
Deep open-circuit trimix decompression courses within RAID limits
Advanced multi-gas decompression training
You act as the final instructional authority for divers entering the deepest open-circuit environments in the RAID system.
This instructor development program focuses on leadership, supervision, and evaluation, rather than personal diving advancement.
You will refine your ability to:
Teach hypoxic trimix theory and gas selection
Instruct deep decompression planning and execution
Manage oxygen exposure and hypoxic risk
Teach gas switching discipline under extreme conditions
Evaluate student decision-making during long decompression
Apply RAID assessment criteria accurately
You will be evaluated on your ability to:
Demonstrate open-circuit skills neutrally buoyant and in trim
Maintain precise buoyancy during deep ascents
Supervise multi-stage decompression profiles
Control student positioning and gas switches
Intervene decisively during failures or stress events
Maintain situational awareness across multiple students
You will develop:
Advanced risk management strategies
Clear instructional command presence underwater
Conservative judgement under extreme task loading
Professional leadership in complex decompression environments
Instructor Level: Leadership / Technical Open Circuit
Gas Scope: Hypoxic Trimix
Teaching Environment: Deep staged decompression with multiple gases
Evaluation Standard: Demonstration-quality skills
Instructor Oversight: RAID Instructor Trainer
Certification Type: Open-circuit (non-CCR)

To enrol in this course, candidates must:
Hold RAID Normoxic Decompression Instructor certification
Be certified as a RAID Hypoxic Decompression Diver
Maintain current RAID professional registration
Hold valid First Aid, CPR, and Oxygen Administration
Meet RAID medical and administrative requirements
Demonstrate extensive open-circuit hypoxic decompression experience as required by RAID
All prerequisites are reviewed during the instructor application process.
Instructor development follows a structured, three-stage progression, aligned with RAID leadership standards.
You will complete leadership-level academics covering:
RAID hypoxic decompression standards and limits
Instructor responsibilities and liability
Student supervision and positioning strategies
Risk management for deep, staged decompression
Multi-gas and hypoxic trimix planning
Teaching methodology and evaluation criteria
Demonstrate demo-quality execution of all required CCR skills, including:
S-Drill and gas donation protocols
Buoyancy and trim under task loading
Gas switch procedures and verification
Decompression stop discipline
Valve shutdowns (where applicable)
SMB deployment while hovering
Lost mask and failure-management drills
Your in-water evaluation includes:
Supervise hypoxic decompression training dives
Maintain instructor positioning and awareness
Control students during deep ascents and gas switches
Manage failures during long decompression obligations
Evaluate student performance objectively
Demonstrate calm, authoritative leadership under pressure
Instant access to your online learning, course preparation modules. Begin training immediately.

Once certified, you will be authorised to:
Teach RAID Hypoxic Decompression Diver programs
Supervise deep hypoxic trimix decompression dives
Certify divers within RAID hypoxic limits
Prepare divers for expedition-level open-circuit diving
This rating represents the highest level of open-circuit decompression instructional authority within RAID.
Your instructor development is delivered and evaluated by a RAID Instructor Trainer with extensive experience in deep hypoxic trimix and long-range decompression instruction.
Training emphasises:
Precision over progression speed
Conservative gas and decompression strategies
Real-world instructional readiness
Consistent, repeatable RAID standards application
The objective is to develop instructors who are trusted, disciplined, and capable of leading divers safely in extreme environments.

Instructor training begins with application review, verification of experience, and coordination with a RAID Instructor Trainer.
