The TDI Inspiration and Evolution Air Diluent course (certification depends on unit/electronics used) is your first step into closed circuit rebreather diving and your first truly quiet diving experience. Using the latest in technology CCR’s maximize your gas supply of Nitrox and provide the optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen (PPO2). During the dives (minimum of six) I will teach you all the necessary skills to conduct CCR dives to a maximum depth of 40 m / 130 feet. The skills include:
Setup and maintenance of the unit
Loop volume management
Calibration of electronics
Emergency procedures
Buoyancy control
CNS tracking
The TDI Inspiration/Evolution manual provides comprehensive information about the units and how they operate during a dive. Also available is the Inspiration/Evolution build-up check list that can be adhered to the unit case for easy reference.
Student Prerequisites: • Minimum age of 18 • Minimum certification of TDI Nitrox Diver or equivalent • Proof of 60 logged open water dives • Minimum certification level of Advanced Nitrox Diver (Advanced Nitrox Diver may be combined with this course) or equivalent from agencies recognized by TDI.
The TDI Inspiration and Evolution Mixed Gas course (certification depends on unit/electronics used) is your next step into closed circuit rebreather diving and with the addition of helium as a diluent gas, it is your opportunity to explore a little deeper. Using the latest in technology CCR’s maximize your gas supply and provide the optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen (PPO2). During the dives (minimum of six) I will teach you all the necessary skills to conduct CCR dives utilizing helium as a diluent gas and oxygen levels as low as 16 percent to a maximum depth of 60 m / 200 feet. The skills include
Calculating off-board gas requirements
Recovering from system failure
Calibration of electronics
Emergency procedures
Removing and replacing off-board gases
Surface marker buoy deployment
The TDI Inspiration/Evolution manual provides comprehensive information about the units and how they operate during a dive, this combined with the TDI Trimix Diver manual complete the academic knowledge needed to conduct mixed gas CCR. Also available is the Inspiration/Evolution build-up check list that can be adhered to the unit case for easy reference.

If the diver has fifty (50) hours on another CCR unit recognized by TDI, only twenty five (25) hours are required to be on the Inspiration / Evolution • Have completed and qualified the TDI Air Diluent Rebreather Course or equivalent from agencies recognized by TDI
The highest level of CCR training that TDI offers, the Inspiration/Evolution Advanced Mixed Gas course will teach you to use the full capabilities of a CCR. With a maximum depth of 100 m / 330 feet this course opens up new wrecks, caves, and walls to explore. This intensive course conducted over seven days will focus on all the elements needed to plan and execute dives to these depths. Topics and skills for this course include
Off board gas calculations and management
Gas shutdowns and loss of gas drills
Equivalent narcotic depth calculation
Recovering from system failure
Labeling and placing of off board gases
Student Prerequisites: • Minimum age of 18 • Have a verified log of a minimum of one hundred (100) CCR hours distributed over a minimum of one hundred (100) dives on the Inspiration / Evolution CCR. Fifty (50) % of these dives must be deeper than one hundred (100) fsw / thirty (30) msw. All to be deeper than twenty (30) fsw / nine (9) msw. If the diver has one hundred (100) hours on another CCR unit recognized by TDI, only fifty (50) hours are required to be on the Inspiration / Evolution • Have completed and qualified the TDI Air Diluent CCR Course or equivalent from agencies recognized by TDI
TDI's Closed Circuit Rebreather Instructor Course, which includes the Evolution, Inspiration, Megalodon and KISS units prepares instructor candidates to teach recreational rebreather diving. Developing basic CCR skills for minimal decompression diving, some of the academic topics include gas physiology, mechanics and electronics of rebreather systems as well as dive planning and emergency procedures.

TDI ISC COPIS Meg Air Diluent CCR Diver (Mod. 1)
This course is designed to teach the user how to dive with the COPIS (Constant Oxygen Pressure Injection System) Meg Closed Circuit Rebreather using air as diluent. The COPIS is a non electronic driven system m-CCR. The m-CCR COPIS Meg rebreather is a diver/operator manual oxygen addition system with a constant oxygen pressure first stage that injects through an orifice system a 0.69 liter per minute (or more) of O2 for the diver. Comes with a flow meter for calibrating the O2 first stage regulator's IP for adjusting the flow rate. The COPIS II does come with a HUD. The course consists of between 6-8 hours of classroom sessions, equipment preparation followed by 4 hours of confined water sessions and 6 Training dives. Pre-study is required, as well as successful completion of the written exam.
