TDI CCR AIR DILUENT DECOMPRESSION PROCEDURES DIVER
Are you an open circuit technical diver 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 of the necessary skills to conduct decompression CCR dives to a maximum depth of 40 meters/130 feet using air diluent.
Who this course is for:
The open circuit technical diver, or entry level CCR diver, looking to utilize CCR technology to extend their depth limits and bottom times.
· Minimum age 18
· Provide proof of 50 logged dives
· Provide proof of TDI Advanced Nitrox Diver and Deco Procedures Diver or equivalent from agencies recognized by TDI
· If the rebreather is a TDI approved Sidemount rebreather, the student must hold the TDI Sidemount Diver certification or equivalent and provide proof of 10 logged Sidemount dives.
· Minimum age 18
· TDI Air Diluent CCR Diver certified or equivalent
· 30 hours on the CCR unit
· Six months CCR diving experience
What you can expect to learn:
The TDI CCR Air Diluent Decompression Diver course takes an in-depth look at all of the following and more:
History and evolution of rebreathers, 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, Proper scrubber packing: in accordance with manufacturers recommendation, Electronic or manual systems design and maintenance, Dive tables, Dive computers, Dive planning, Emergency procedures, Dive checklists and Predive checks.
Some of the required skills you will have to demonstrate include the following:
All open water dives must be between 9 meters/30 feet to 40 meters/130 feet
The diving activities approximate those of training
Two dives must be deeper than 20 meters/66 feet and two dives must be deeper than 30 meters/100 feet
PO2 not to exceed manufacturer’s recommendation or a working limit of 1.3 bar
All dives to be completed within CNS percent limits with a recommended maximum of 80 percent of the total PO2 CNS limit
Safety stops to be conducted with a minimum 3 minutes at 6 meters/20 feet
When the user opts for an automatic diluent valve (ADV) fitted by the manufacturer, additional skills such as regular diluent gauge monitoring and
addition control must be emphasized
Calculate all off-board gas at 45.30 liters/1.6 cubic feet per minute usage to cover stress situations
All dives to be completed within appropriate constant PO2 decompression tables
Students must do one bailout from depth on open circuit to include simulated decompression
Pre dive checks utilizing the TDI Pre-flight checklist or manufactures required pre-dive checklist
We make sure that you are able to dive save with your unit, and we learn you all the skills and details the manufacture specifies.
What’s in it for you?
Upon successful completion of this course, graduates may engage in decompression diving activities utilizing the CCR they were trained to dive with, without direct supervision of the TDI Instructor so long as the following limits are adhered to:
The areas of activities approximate those of training.
Environmental conditions approximate those of training.
To a maximum depth of 40 meters/130 feet
