TDI Decompression Procedures Course

Prerequisites:

• Minimum age: 18 years.
• Minimum certification: SDI Advanced Adventure Diver, SDI Advanced Diver, or equivalent.
• 25 logged open water dives.

Once certified, you will be able to:

• Participate in staged decompression dives without direct supervision.
• Plan and execute profiles with mandatory stops within conditions similar to your training.
• Use air, Nitrox, or oxygen as decompression gases according to your certification level.
• Enroll in advanced TDI technical courses such as Advanced Nitrox, Extended Range, Advanced Wreck, or Trimix.

What you will learn:

• Differences between safety stops and mandatory decompression stops.
• Physics applied to technical diving and a review of pressure.
• Decompression physiology.
• Advantages of hyperoxic mixes in decompression.
• Stress management, task loading, and psychological aspects in technical diving.
• Decompression options: air, Nitrox, and oxygen.
• Equipment configuration.
• Decompression models and the use of tables and multi-level dive computers.
• Standard planning and emergency planning.
• Descent, ascent, and decompression procedures, including fixed or drift methods.
• Management of primary and decompression gases, including analysis and logging.

Practical skills:

• Comprehensive planning of dive and decompression profiles with gas and exposure limits.
• Application of the START protocol before each dive.
• Advanced buoyancy and trim control in all phases.
• Management and switching to decompression gases.
• Deployment and use of a decompression marker buoy, fixed or drift.
• Controlled staged ascents.
• Response to failures: gas loss, free-flowing regulator, inflator malfunction, line loss.
• Share bottom and decompression gas in a simulated emergency scenario.
• Modify the plan in contingency scenarios.
• Conducting the dive within predetermined limits.

Course Duration and Price:

• This course has a duration of 4 full days.
• If combined with the TDI Advanced Nitrox course, the duration is 6 days.
