IART Standards & Procedures
Inspiration / Evolution
Extended Range LEVEL II
Closed Circuit Rebreather "Extended Range" Diver Level II
B) Course objective:
This course is designed to provide experience and training with the
Inspiration or Evolution CCR for either:
CCR II Extended Range (Air) Diver – This course pr
ovides the opportunity to safely learn
the techniques and theory for CCR decompression dives with air diluent to a maximum
depth of 50m
CCR II Extended Range (Normoxic Trimix) Diver – This course provides the opportunity
to safely learn the techniques and theory for CCR decompression dives with air and
normoxic Trimix diluent to a maximum depth of 50m and 60m respectively
minimum 18 years of age, certification as an IART CCR I Diver or
equivalent, proof of a minimum of 50 hours diving the Inspiration or Evolution and a valid
D) Course content/duration:
- 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.
– 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.
E) Support material:
IART CCR Level II manual, NOAA 0
-exposure tables, standard air
decompression tables. Computer-based dive tables such as Z-Plan, ProPlanner, etc.,
flash-cards, Instructor manual and Instructor presentation materials.
F) 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 50m and normoxic Trimix 60m. At
least 3 dives should be conducted at a minimum of 40m depth and require a
decompression stage. Maximum decompression requirements during training should not
exceed 5 minutes at 3 metres for option A and 20 minutes for option B normoxic Trimix
H) 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.
IART Standards & Procedures
I) 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. In accordance
with IART quality control, the student and Instructor are required to fill in the training
protocol form. The instructor must retain this form with the student file.
K) Certification Renewal:
