JJ-CCR Level 1

The JJ-CCR is a fully-closed, electronically controlled rebreather operating with Shearwater electronics and a HUD system that performs an additional sensor calibration.

The JJ-CCR is a robust, well-engineered, no-nonsense rebreather with multiple redundant systems on board and manual override options. It is primarily designed to work with back-mounted counterlungs leaving the chest area free of encumberments. This is a unit that can meet the demands of every rebreather diver including those wishing to undertake deep Trimix diving. Its performance potential is enormous.

For this reason a comprehensive, dedicated training is essential. The IART unit-specific user course, combined with the use of the course manual, will prepare you with the knowledge and skills needed to safely dive the JJ-CCR within the limits set by the Level I standards. It covers, in addition to extending and deepening the theoretical knowledge of the participant, training in pool/confined water and 6 open water dives with not less than 300 minutes in-water time on the JJ-CCR.

The instructor : student ratio is not permitted to exceed 1:2.

This course will prepare you to become a competent, disciplined and knowledgeable JJ-CCR diver who understands:

  • The physiological principles behind rebreather diving
  • The construction of the unit including assembly, disassembly, cleaning and maintenance
  • The possible dangers and potential mistakes
  • How to employ the best diving techniques with the unit
  • How to rescue another rebreather diver

The training reflects the standards required by the manufacturer of the rebreather. IART is authorized by the manufacturer to conduct this training. The course manual is constantly revised and improved in consultation with the manufacturer to reflect new developments resulting from technical improvements or gained through dive experience. You will receive the current edition from your IART JJ-CCR instructor.

JJ-CCR Level 1 Standards

  1. Course: Closed Circuit Rebreather Diver Level I (CCR I). No decompression dives. Air diluent
  2. Course objectives: This course develops in the participant, the required abilities, knowledge and techniques to dive responsibly with the closed circuit JJ-CCR rebreather within sport diving and no-decompression limits. After successful completion of the course the participant is granted the permission to dive with and purchase the JJ-CCR.
  3. Pre-requisites: 50 logged dives, Advanced Open Water, CMAS**, BSAC Sport Diver or equivalent qualification, Nitrox Diver certification and a valid diving medical.
  4. Course content/duration: All theoretical and practical aspects of diving with the JJ-CCR rebreather as described in the IART manual. In addition to time spent by the participant reading through the manual, the course duration is generally four-five days. It covers, in addition to extending and deepening the theoretical knowledge of the participant, training in pool/confined water and open water with not less than 300 minutes in-water time on the JJ-CCR. The instructor:student ratio is not permitted to exceed 1:2.
  5. Training aides: IART CCR manual Level I, air/nitrox dive tables, NOAA exposure tables, flash-cards, personal instructor materials.
  6. Mandatory equipment: complete diving equipment suitable to the environment, bail-out cylinder und regulator with min. 600 litres supply, slate and pencil, depth gauge and timer or dive computer.
  7. Limits: max depth Pool/confined water: 5m. OW dive 1: max. 10m, OW dives 2 – 4: min. 10m – max 20m, OW dives 5 + 6: min. 15m – max. 30m. Nodecompression CCR dives planned to remain within limits of O/C nitrox tables.
  8. Dive skills: all skills contained in the IART CCR Level I manual must be taught and performed according to the required standards.
  9. Requirements for certification: Following completion of the theory lessons a written test must be passed. After successful demonstration of all required practical diving skills the certification is documented by the issue of a certificate and a positive identification card (PIC). In accordance with IART quality control, both the participant and instructor must sign the appropriate training protocol. The Instructor must retain this protocol with the student’s other training documents.
  10. Certification: issued by IART HQ
  11. Certification renewal: not required
