CCR MIXED GAS

REBREATHER > TDI
TDI CCR MIXED GAS DIVER
As a TDI CCR Air Diluent Decompression or Helitrox Diluent Decompression Diver, the TDI Mixed Gas CCR Diver course is your next step into closed circuit rebreather diving, 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 your TDI Instructor 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 metres/200 feet.

Who this course is for:
  • The certified TDI Air Diluent Decompression or Helitrox Diluent Decompression Diver (or equivalent) looking to extend their depth limitations.

Course prerequisites:
  • Minimum age 18
  • Provide a verified log of a minimum of 50 rebreather hours distributed over a minimum of 50 dives on the specific rebreather. If the diver has 50 hours on another CCR unit recognized by TDI, only 25 hours are required to be on the specific unit
  • Have completed and qualified the TDI Air Diluent Decompression Procedures Rebreather/TDI CCR Helitrox Diluent Decompression Procedures Diver course or equivalent from agencies recognized by TDI

What you can expect to learn:
The TDI Diving Rebreathers Student Manual is required for use as a review/recap document. The instructor may use any additional text or materials they feel will represent the topic in an educational manner. The following topics must be covered during the course
Gas physiology, oxygen (O2) toxicity, hypoxia, nitrogen absorption, helium absorption, HPNS, carbon dioxide (CO2) toxicity, gas consumption,  gas mixing
  • Formula Work, oxygen (O2) metabolizing calculations, manually controlled closed circuit rebreathers, equivalent narcosis depth theory, central nervous system (CNS) tracking, oxygen tracking units (OTU), gas management, dive tables, dive computers, equipment maintenance.
Required Skill Performance and Graduation Requirements
The following open water skills must be completed by the student during open water dives with the following course limits
No dives deeper than 60 metres/200 feet, no dives shallower than 40 meters/130 feet, other than the 1 air diluent configuration dive are credited toward the dive requirements. Subsequent training dives in shallow water are permitted if necessary during the course, equivalent narcosis depth not to exceed 30 metres/100 feet, calculate all off-board gas at 45.30 litres/1.06 cubic feet per minute usage to cover stress situations, PO2 not to exceed manufacturer recommendation or a working limit of 1.3 bar during the bottom phase of the dive and 1.4 bar during the decompression phase of the dive, diluent PO2 should not exceed 1.2 at maximum depth, all dives to be completed within appropriate fixed PO2 decompression tables or decompression planning software, all dives to be completed within CNS percentage limits with a recommend maximum of 80 percent of the total PO2 CNS limit, the student is only certified for CCR mixed gas diving on the rebreather being used and land Drills.
We also go over:   Pre-dive Drills, Open Water Skills and we make sure that you are ready for diving the unit save.

What’s in it for you?
Upon successful completion of this course, graduates may engage in technical diving activities utilizing the unit specific CCR to a maximum of 60 metres / 200 feet, utilizing a mixed gas diluent containing 16 percent or greater oxygen provided:
  • The diving activities approximate those of training
  • The areas of activities approximate those of training
  • Environmental conditions approximate those of training
  • Ability to enroll in TDI Advanced Mixed Gas CCR Diver course

TDI CCR Mixed Gas Diver minimum requirements:
  • Complete to the instructors satisfaction all confined and open water skill development sessions
  • Demonstrate mature, sound judgment concerning dive planning and execution
  • Course must be completed within 6 weeks from the starting date
  • Complete a refresher course following a period of inactivity greater than 6 months following the course
