TDI Advanced Wreck Diver – Master Overhead Diving
Category: Technical Diving Course
Location: Koh Chang
SKU: Tech-Koh-Chang-TDI003
Course Overview
This course is designed for divers who want to safely penetrate wrecks in an overhead environment. You will learn proper guideline use, propulsion techniques, gas management and redundancy setups to explore areas beyond the light zone – or stay in the light zone with a flexible no-decompression training option.
Our training is conducted on the HTMS Chang, the largest wreck in Thailand, and includes additional training on T11 and PAK1 expeditions.
⚠️ Penetration Depth Limitation:
Penetration into overhead environments is limited by your current certification depth. For example, if you’re a recreational diver certified to 40 m, and enter the wreck at 32 m, your maximum penetration distance is 8 m. The TDI Advanced Wreck certification allows full penetration within these depth boundaries.
Recreational or Technical – This Course is for You
Already a certified Deep and Wreck Diver with 50+ logged dives? Or are you a TDI Advanced Nitrox or Decompression Procedures diver looking to sharpen your overhead environment skills?
Then join the TDI elite wreck diver team and take your exploration deeper, safer, and more precise than ever before.
