TDI Decompression Procedures

Are you finding that your no-decompression limits (NDLs) are restricting your dives? Do you often have to ascend earlier than desired? As recreational divers, planned decompression is typically not part of our repertoire or training. The TDI Decompression Procedures Course is designed to prepare you for staged decompression diving. With a maximum operating depth of 45 meters/150 feet, this course serves as your gateway beyond conventional recreational diving boundaries. Combining the TDI Decompression Procedures Course with the TDI Advanced Nitrox course lays the groundwork for further advancement in technical diving. Upon completion of these courses and gaining additional experience, you'll be ready to progress to higher technical levels.

Who this course is for:

• Certified Advanced Divers seeking to enhance their understanding of decompression theory and diving techniques
• Certified Advanced Divers looking to extend their bottom time
• Certified Advanced Divers interested in pursuing further education in technical diving

What you can expect to learn:

The Decompression Procedures course covers various aspects of decompression dive planning, including:

• Selection of decompression gases
• Comparison of tables vs. personal dive computers
• Emergency and contingency planning (e.g., equipment failure, omitted decompression)
• Procedures for conducting decompression dives
• Equipment selection and pre-dive checks
• Stress analysis and mitigation techniques
• Following a decompression schedule and gas switching
• Team awareness, communication, and deployment of surface marker buoys (SMBs)/lift bags
• Proper trim, buoyancy, and finning techniques
• Emergency procedures for equipment failures, gas loss, navigational errors, etc.
• Equipment considerations, cylinder labeling, nitrox mixture analysis, and gas blending procedures

What’s in it for you?

Upon completion, you'll gain the ability to:

• Conduct decompression dives independently, without direct supervision, under conditions similar to those encountered during training
• Enroll in TDI Advanced Nitrox, TDI Extended Range, TDI Advanced Wreck, and TDI Trimix courses

TDI Decompression Diver minimum certification requirements:

• Satisfactorily complete the TDI Decompression Procedures course written examination
• Successfully fulfill all open water requirements in a safe and efficient manner
• Demonstrate mature and sound judgment concerning dive planning and execution
