ISC Megalodon CCR Level 1 E

The Megalodon CCR Rebreather is a precision engineered machine sporting double heavy-duty o-ring seals on all connections, a heavy-duty aluminium stack where the electronics and a 2.5 kilo carbon dioxide (Co2) axial absorbent canister are housed. Fitted with an Automatic Diluent Valve ( ADV ) and a Head Up Display ( HUD ) enabling the diver to monitor the pO2 at all times.

The unit is available in two versions, either a computer controlled closed circuit (eCCR) or a manually controlled closed circuit rebreather (mCCR). In the electronically controlled APECS version an onboard computer maintains the oxygen partial pressure (Po2) in the breathing loop to the demand of the diver. In the manually controlled COPIS version the diver monitors loop Po2 on the display and manually injects oxygen as needed to maintain the desired setpoint.

The Megalodon is a very robust, high performance rebreather ideally suited to the technical diver. For this reason a comprehensive, dedicated training is essential. The IART unit-specific user course, combined with the unit specific IART manual, will prepare you with the knowledge and skills needed to safely dive the Megalodon CCR 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

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 ISC Megalodon CCR instructor.
