Advanced Wreck

The TDI Advanced Wreck Diver Course is the next step for any diver that has successfully completed the SDI Wreck Diver Course. During this course, your TDI Instructor will teach you the proper techniques for locating and planning an advanced penetration dive. The advanced wreck course is commonly taught with other popular TDI courses such as Advanced Nitrox, Decompression Procedures, Extended Range, Closed Circuit Rebreather, and Trimix.

What you can expect to learn

  • Use of advanced wreck diving equipment including:
    • Primary cylinder(s)-dual outlet single tank, independent doubles, or doubles with isolation manifold
    • Decompression/stage cylinders
    • Redundant primary regulators
    • Primary and back-up lighting systems
    • Penetration/safety reels
    • Lift bag/SMBs
  • Wreck penetration procedures
    • Equipment selection
    • Pre-dive checks and drills
    • Stress analysis and mitigation
    • Guideline use, deployment, following, retrieval
    • Team awareness and communication
    • Emergency procedures (equipment failures, catastrophic gas loss, omitted decompression, navigational errors, entrapment/entanglement, loss of visibility, injured/unconscious diver, etc)
    • SMB/lift bag deployment
  • Proper trim, buoyancy and propulsion techniques
