Are you finding your no- decompression limits (NDLs) a limiting factor to dives? Do you have to ascend sooner than you would like? As sport divers, planned decompression is not something that we do or have been taught.The TDI Decompression Procedures Course prepares you for planned staged decompression diving. With a maximum operating depth of 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. The TDI Decompression Procedures Course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.
What you can expect to learn
- Decompression dive planning including:
- Decompression gas choices
- Tables vs. personal dive computers
- Emergency and contingency planning (equipment failure, omitted decompression, etc.)
- Decompression diving procedures
- Equipment selection
- Pre-dive checks and drills
- Stress analysis and mitigation
- Following a decompression schedule
- Gas switching
- Team awareness and communication
- SMB/lift bag deployment
- Proper trim, buoyancy and finning techniques
- Emergency procedures (equipment failures, catastrophic gas loss, omitted decompression, navigational errors, etc.)
- Equipment considerations, cylinder labeling, analyzing nitrox mixtures, and gas blending procedures
Course Equipment Requirements
The following equipment is required for each student:
- Primary cylinder(s), cylinder volume appropriate for planned dive and student gas consumption
Note: Independent and isolated back-mounted doubles, are allowed to be used.
- Decompression mix cylinder(s)
- Cylinder volume appropriate for the planned dive and student gas consumption with submersible pressure gauge
- Labeled in accordance with TDI Standards
- Depth gauge and automatic bottom timer and / or dive computer
- Primary and alternate 2nd stage required on all primary cylinders
- Submersible pressure gauges are required on all primary cylinders
- Minimum age 18
- Minimum certification of SDI Advanced Adventure Diver, Advanced Diver, or equivalent
- Proof of 25 logged open water dives
