What Is TDI CCR Air Diluent (Mod 1)?
CCR Air Diluent (Mod 1) is a full rebreather certification that trains divers to safely operate a closed-circuit rebreather using air as the diluent gas.
The course focuses on building reliable CCR habits: equipment preparation, checklist use, in-water control, bailout readiness, and disciplined responses to common and uncommon failures.
What You’ll Learn in CCR Mod 1
- CCR system assembly, inspection, and pre-dive preparation
- Checklist-driven habits before, during, and after every dive
- Loop management and oxygen monitoring
- Bailout planning and execution
- Failure recognition and disciplined response strategies
- Buoyancy, trim, and situational awareness while task loaded
This course emphasizes consistency and control — not pushing limits.
Is CCR Mod 1 Right for You?
CCR Mod 1 is appropriate for divers who:
- Have solid buoyancy and trim on open-circuit scuba
- Are comfortable following checklists without shortcuts
- Can manage task loading calmly and deliberately
- Understand that CCR safety depends on discipline, not automation
CCR is not forgiving of complacency. This course requires focus, preparation, and a methodical mindset.
CCR Mod 1 Training in Mid-Atlantic Conditions
Cold water, reduced visibility, current, and variable surface conditions increase task loading and amplify small mistakes.
Training in Mid-Atlantic environments builds resilient CCR divers who can execute procedures cleanly when conditions aren’t ideal.
What Comes After CCR Mod 1?
After mastering air diluent CCR fundamentals, divers may continue into more advanced CCR training based on experience, unit type, and goals.
