Shipwrecks are incredibly intriguing spots to dive. While it’s interesting to dive around them, there’s a certain pull divers feel to go inside wrecks. But diving inside a closed environment can be a dangerous activity and requires special training, which is exactly what you’ll get on our TDI Advanced Wreck course.

How do you mark your path so that you don’t get lost inside a wreck? What do you do if you experience a complete silt-out? How do recover your line if you accidentally lose it? The TDI Advanced Wreck course will prepare you for all these scenarios.

The TDI Advanced Wreck diver course is the next step for any diver that has successfully completed the Wreck Diver course. Your instructor will teach you the proper techniques for locating and planning an advanced penetration dive. The TDI Advanced Wreck course is commonly taught with the Advanced Nitrox course, Decompression Procedures course, and Extended Range course.

During the course you can expect to learn about the use of advanced wreck diving equipment including primary cylinders, independent doubles, or doubles with isolation manifolds, decompression and stage cylinders, redundant primary regulators, primary and back-up lighting systems, penetration and safety reels, and lift bags and SMBs. You’ll also learn about 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, proper trim and propulsion techniques.

To register for the TDI Advanced Wreck course you must be 18 years old with an advanced certification. You must also have already taken the TDI ANDP and Wreck Diver course and have 50 logged dives.

Big Blue Tech will provide all equipment and materials necessary to complete the TDI Advanced Wreck course. However, at this level, divers are expected to have a primary mask, computer, and technical wrist slates. These items can also be rented for the entire course at a minimal cost.

The schedule for the TDI Advanced Wreck course generally looks like this.

Day 1


You’ll meet your instructor in our partner restaurant, Blue Water, and begin with some course academics. You’ll also start to go through the special equipment considerations for advanced wreck and penetration diving.


You’ll spend the afternoon in a confined water environment practising and perfecting the skills you’ll need for advanced wreck and penetration diving.

Day 2


You’ll finish up with the course academics on the morning of day two and take your course exam. Once you pass, you’ll be ready to try your new skills out on some wreck penetration dives.


In the afternoon, you’ll head out on our big boat and you’ll do dives one and two for the course at the HTMS Sattakut, our training wreck located right off Sairee Beach.

Day 3


You’ll spend the morning of the third day going through some detailed dive planning with your instructor. You’ll plan your dives for the afternoon.


You’ll be out diving again on the afternoon of the third day. You’ll execute the dive plan you spent the morning putting together.

Day 4


The final day of the course will be much like the third day. Again, you’ll spend the morning practising your dive planning skills with your instructor. You’ll plan your dives for the afternoon.


You’ll be out diving again on the afternoon of the final day. You’ll execute the dive plan you spent the morning putting together.

Don’t forget! Because of the extra nitrogen your body builds up while scuba diving, you cannot fly within 24hrs of your last dive.
