Extended Range Diving

Are you finding your no- decompression limits (NDLs) a limiting factor to dives? Do you have to ascend sooner than you would like? As sport divers, planned decompression is not something that we do or have been taught.

 

The Decompression Procedures course prepares you for planned staged decompression diving. With a maximum operating depth of 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. The Decompression Procedures course combined with the Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.

Who this course is for:

  • The certified Advanced Diver looking to expand their knowledge of decompression theory and diving techniques
  • The certified Advanced Diver who is interested in extending their bottom time
  • The certified Advanced Diver who has interest in moving forward with technical diving education

Course prerequisites:

  • Minimum age 18
  • Minimum certification of PADI Advanced Diver or equivalent
  • Proof of 25 logged open water dives
  • For the Decompression Procedures the Advanced Nitrox course is required.

What you can expect to learn:

  • Decompression dive planning including:
    • Decompression gas choices
    • Tables vs. personal dive computers
    • Emergency and contingency planning (equipment failure, omitted decompression, etc.)
  • Decompression diving procedures
    • Equipment selection
    • Pre-dive checks and drills
    • Stress analysis and mitigation
    • Following a decompression schedule
    • Gas switching
    • Team awareness and communication
    • SMB/lift bag deployment
  • Proper trim, buoyancy and finning techniques
  • Emergency procedures (equipment failures, catastrophic gas loss, omitted decompression, navigational errors, etc.)
  • Equipment considerations, cylinder labeling, analyzing nitrox mixtures, and gas blending procedures

What’s in it for you?

  • Ability to conduct decompression diving activities without direct supervision provided:
    • The diving activities approximate those of training
    • The areas of activities approximate those of training
    • Environmental conditions approximate those of training

Decompression Diver minimum certification requirements:

  • Satisfactorily complete the Decompression Procedures course written examination
  • Complete all open water requirements safely and efficiently by Instructor standards
  • Demonstrate mature, sound judgment concerning dive planning and execution
