TDI Advanced Wreck trains qualified divers to plan and conduct more serious wreck penetration dives with technical-level preparation. The official TDI page describes it as the next step after SDI Wreck Diver, with instruction in locating and planning advanced penetration dives. It is often taught alongside Advanced Nitrox, Decompression Procedures, Extended Range, CCR, or Trimix because wreck penetration can combine overhead, depth, gas, and decompression challenges.
This course is for basic wreck divers who want to learn proper advanced penetration techniques and continue technical education. TDI lists minimum age 18, SDI Advanced Adventure Diver or equivalent, SDI Wreck Diver or TDI Cavern Diver or equivalent, and proof of 50 logged dives as prerequisites. Students should already have strong buoyancy, trim, situational awareness, and the maturity to manage overhead risk.
Training covers advanced wreck equipment, redundant regulators, stage or decompression cylinders, lighting systems, penetration and safety reels, SMB or lift bag use, guideline deployment and retrieval, team communication, stress analysis, emergency scenarios, entrapment or entanglement, catastrophic gas loss, navigational errors, loss of visibility, and injured-diver procedures. In High Springs, Florida, it can be paired with broader technical training before wreck-focused travel. Successful students should leave with a structured approach to wreck penetration planning and execution.
