TDI CCR Air Diluent Compression (45m)

Are you an open circuit technical diver (ie TDI Decompression Procedures Diver or equivalent) looking to cross over to the “silent” side? Or maybe you are a CCR Air Diluent Diver looking to progress to the next level? Either way, TDI’s CCR Air Diluent Decompression Course is the next step.

Using the latest technology in CCR’s can maximize your gas supply and provide an optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen. Like having a blending station on your back, a CCR is the ultimate tool for technical divers.

During this course, your TDI Instructor will teach you all the necessary skills to conduct decompression CCR dives to a maximum depth of 45 metres using air diluent.

The Training

  • Online learning – once you have signed up for the course, (if you did not get training materials with a 30m course)  we will provide you with a TDI CCR online code for the Megaladon, Pathfinder and SF2 courses OR the TDI manual for APD’s Inspiration and Evolution units, depending on which unit you are completing the course, so you can do all your studying at home before you come to the dive centre. You also need to have a copy of the manufacturer’s manual for the specific unit.  You will cover areas such as:
  • Comparison of Open Circuit (OC), closed circuit, and Semi-closed Circuit Rebreather (SCR) systems noting the pros and cons of each
  • Practical mechanics of the system
  • Gas physiology
  • Dive tables
  • Dive computers
  • Classroom – You will then review key areas and practise key dry skills with your instructor including the following:
    • Proper scrubber packing: in accordance with manufacturers recommendation
    • Electronic or manual systems design and maintenance
    • Dive planning
  • Practical training – After you have reviewed the key knowledge areas and ready to go you will then join your instructor for the practical element of your training and cover the following areas:
    • Unit specific skills
    • Managing PO2 within manufacturers specifications
    • Diluent monitoring
    • Calculating deep bailout gas
