TDI HELITROX DECO PROCEDURES CCR DIVER COURSE

This is the second level certification course for divers wishing to utilize a Closed-Circuit Rebreather (CCR) for mixed gas diving using a Helitrox Diluent. The objective of the course is to train divers in the benefits, hazards, and proper procedures for diving a CCR and to develop basic CCR diving skills, to a maximum of 45 metres/150 feet, using an air/nitrox/helium diluent for formal decompression diving. Students are permitted to utilize a diluent and bailout mix with no greater than a 35% helium content and no less than a 21% oxygen content and are permitted to use up to 100% oxygen for decompression.

WHO THIS COURSE IS FOR

  • The certified TDI Air Diluent Diver (or equivalent) who is looking to extend their depth limitations, learn CCR decompression procedures, and reduce narcosis
  • The open circuit TDI Advanced Nitrox and Decompression Procedures or Helitrox Diver looking to utilize CCR technology to extend their depth limits and bottom times
  • Appropriate theory for the course. This can be assigned to you on payment of the deposit

COURSE PREREQUISITES

  • Minimum age 18
  • Proof of 50 logged dives
  • Minimum certification level of TDI Advanced Nitrox Diver, Deco Procedures Diver or Helitrox 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

OR

  • Minimum age 18
  • TDI Air Diluent CCR Diver certified or equivalent
  • 30 hours on the CCR unit
  • Six months CCR diving experience

SKILL PERFORMANCE

All standards set by both TDI and the rebreather manufacturer must be met, while maximum limits of neither may be exceeded.

The following open water skills must be completed by the student during open-water dives with the following course limits:

  • All open water dives must be between 9 metres/30 feet to 45 metres/150 feet
  • Two dives must be deeper than 20 metres/66 feet and one dive must be deeper than 30 metres/100 feet
  • PO2 not to exceed manufacturer recommendation or a working limit of 1.3 bar
  • All dives to be completed within CNS% limits with a recommend maximum of 80% of the total PO2 CNS limit
  • Safety stops to be conducted with a minimum 3 minutes at 6 metres/20 feet
  • Where 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 45.3 litres/1.06 cubic feet per minute usage to cover stress situations
  • All dives to be completed within appropriate constant PO2 decompression tables
  • Student is only certified for Helitrox decompression diving on the specific CCR unit
  • Students must do one bailout from depth on o/c to include simulated decompression

WHAT'S IN IT FOR YOU

Upon successful completion of this course, graduates may engage in decompression diving activities utilizing a CCR without direct supervision provided:

  • The diving activities approximate those of training
  • The areas of activities approximate those of training
  • Environmental conditions approximate those of training

Upon successful completion of this course, graduates are qualified to enrol in:

  • TDI Mixed Gas CCR unit specific course
  • TDI Advanced Wreck Course

MINIMUM REQUIREMENTS

  • Satisfactorily complete the written examination with a pass mark of 80% and 100% remediation
  • Complete to the instructor’s 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
