c_171_171_16777215_00_images_iart4.jpgThis "Extended Range" course is designed to provide experience and training on with a JJ-CCR unit with one of two options, Air or Normoxic Trimix.

Decompression. Air or Normoxic Trimix. 40-60 metres maximum depth based on options.

Course Options

Option A:
CCR II Extended Range (Air) Diver – This course provides the opportunity to safely learn the techniques and theory for CCR decompression dives with air diluent to a maximum depth of 40m

Option B:

CCR II Extended Range (Normoxic Trimix) Diver – This course provides the opportunity to safely learn the techniques and theory for CCR decompression dives with normoxic Trimix diluent to a maximum depth of 60m.


  • Minimum 18 years of age
  • Certification as an IART CCR I Diver or equivalent
  • Proof of a minimum of 50 hours diving the JJ-CCR
  • A valid diving medical


Course content/duration:

Option A:
All theoretical and practical aspects of deep (air diluent) and decompression diving. The classroom sessions explain the physical and physiological hazards of deep
diving, the decompression planning, equipment considerations for deep diving, the need of bail-out gas, and all procedures involved. An important point is dive planning using computer-based dive tables such as Z-Plan, Proplanner, etc. The practical part of the course includes 4 dives over at least 3 days with a minimum accumulated dive time of 180 minutes. The instructor-to-student ratio is 1:2.

Option B:
Covers all aspects of option A with additional normoxic Trimix theory and 2 normoxic Trimix dives. In total 6 dives over at least 5 days with a minimum accumulated dive time of 300 minutes. The instructor-to-student ratio is 1:2.

Required Materials

IART CCR Level II manual, NOAA 02-exposure tables, standard air decompression tables. Computer-based dive tables such as Z-Plan, ProPlanner, V-planner etc.

Required equipment

Complete diving equipment, separate bail-out cylinder, lift bag, safety reel, knife or tool, decompression table, slate, depth gauge and bottom timer or computer. The rebreather should be equipped with an oxygen bail-out second stage.


The maximum depths during training are: Air 40m and normoxic Trimix 60m. At least 2 dives should be conducted at a minimum of 40m depth and a minimum of 3 dives should require a decompression stop. Maximum decompression requirements during training should not exceed 10 minutes at 3 metres for option A and 15 minutes for option B normoxic Trimix dives.

Practical skills

The dives should include the proper planning, including calculation of dive profile, gas analysing and labelling, equipment familiarization (Stage bottle
removal/replacement, oxygen bail-out regulator use), emergency and out-of-air procedures (gas sharing, rescue ascent, etc.), ascent reel and lift bag deployment, and
proper decompression techniques.

Certification requirements

The student must satisfactorily complete a written exam.
Once training requirements are met at the Instructor's discretion, it is necessary to submit an application in order to obtain the corresponding IART certification card.
Certification is issued by IART HQ and does not require renewal.
