The objective of the course is to train divers in the safer use of Rebreathers for dives using normoxic helium based gas mixtures.
The knowledge and skills taught in this program are designed to qualify divers to perform Normoxic
Trimix Dives up to 200 fsw (60 msw) or Normoxic Trimix Plus dives up to 233 fsw (70 msw).

The course objective included the following:

1. Identify the steps in planning an Advanced EANx/Advance Recreational Trimix CCR dive
2. Identify the two greatest hazards when planning CCR dives
3. Understand what is meant by Runtime variation planning

8. What is oxygen toxicity and the signs and symptoms of oxygen toxicity
9. A basic understanding of Carbon Dioxide physiology
10. Describe what is Hyperventilation or Hypocapnia
11. What is and the signs and symptoms of Hypercapnia
12. Steps you can take to avoid CO2 problems
13. To describe the difference between adsorption and absorption
14. What is the definition of surface equivalent value
15. What is soda lime and how it scrubs CO2 from the breathing loop
16. What is the difference between an axial and a radial canister
17. Why its important to properly pack the scrubber canister
