ISC Pathfinder CCR Level 1

The Pathfinder CCR is a compact, lightweight but very robust, travel-friendly closed circuit rebreather using ISCan Electronics. IScan™ is a Controller Area Network system based upon proven ISO standards used in the automotive, aerospace and defence industries designed to allow independent devices to communicate and interact with each other. Handsets, HUDs and various sensors can operate independently and in concert to increase safety, redundancy and to reduce single points of failure.

The Pathfinder has a Shearwater Petrel pO2 controller customized for ISC with integrated deco-software and an independent colour-coded HUD. It has a radial scrubber as standard. The high-quality engineering but modest weight of this unit makes it attractive to all types of rebreather diver.

The IART training reflects the standards required by the manufacturer of the rebreather. IART is authorized by the manufacturer to conduct this training. This 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 Pathfinder Instructor. Older editions should not be used.

The course “Pathfinder CCR DIVER – Level 1” trains and certifies the user to dive within no-decompression limits to a maximum depth of 40m.

Theory Presentation:

  • Includes review of nitrox theory, physics and physiology
  • Familiarisation with all rebreather components
  • Dive planning and execution and emergency procedures
  • A written exam concludes the theoretical development.

Practical training:

  • Unit preparation, pre-dive checks
  • Disassembly, cleaning and disinfection
  • Dive planning
  • Dive techniques in confined water followed by open water environments
  • Protocol in emergency situations

ISC Pathfinder CCR Level 1 Standards

A) Course: Closed Circuit Rebreather Diver Level I (CCR I). No decompression Air diluent.
B) Course objectives: This course develops in the participant, the required abilities, knowledge and techniques to dive responsibly with the ISC
Pathfinder closed circuit 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 ISC Pathfinder CCR.
C) Pre-requisites: 50 logged dives, Advanced Open Water or equivalent qualification, Nitrox Diver certification and a valid diving medical.
D) Course content/duration: All theoretical and practical aspects of diving with
the ISC Pathfinder CCR as described in the IART-manual. In addition to time spent by the participant reading through the manual, the course duration
is generally 5-7 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 a total of 60 minutes confined water and 300 minutes open water time on the Pathfinder CCR. The instructor : student
ratio is not permitted to exceed 1:2.
E) Training aides: IART CCR manual Level I, air/nitrox dive tables, NOAA exposure tables, flash-cards, personal instructor materials.
F) Mandatory equipment: complete diving equipment suitable to the environment, recommended 7 litre (minimum 3 litre) bail-out cylinder and
regulator with a 2 metre regulator hose, low pressure inflation hose and SPG, slate and pencil, depth gauge and timer or dive computer.
G) Limits: max depth Pool/confined water: 5m. OW dive 1: max. 10m, OW dives 2 + 3: min. 10m – max 20m, OW dive 4 : min. 15m – max. 30m, OW dives 5+6
min. 20m – max 30m CCR dives planned to remain within CCR no decompression limits or no-decompression limits of OC nitrox tables if no CCR
computer is used. No dive may exceed a maximum duration of 2 hours.
H) Dive skills: all skills contained in the IART CCR Level I manual must be taught and performed according to the required standards.
I) 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.
J) Certification: issued by IART HQ
K) Certification renewal: not required
