Decompression procedures

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 45m/150 feet, this course is your first step beyond the normal sport diving limits.
Your Instructor Larry Babcock will provide you with valuable information and skills, among the topics covered are Kit set-up

Equipment requirements
Decompression techniques
Decompression breathing gases
Gas management
Contingency planning
Problem solving procedures

The TDI Decompressions 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.

Open Water Execution 

1. Four dives are required, 2 of those dives must be deeper than 30 metres / 100 feet 

2. If advanced nitrox is taught in conjunction with decompression procedures only a total of 6 dives are required 

3. Only 2 dives from advanced wreck course may be credited towards the total dives required 

 Required Equipment 

The following equipment is required for each student: 

1. 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. 

1. Decompression mix cylinder(s)

b. Labeled in accordance with TDI Standards 

2. Depth gauge and automatic bottom timer and / or dive computer 

3. Regulator(s) 

a. Primary and alternate 2nd stage required on all primary cylinders 

b. Submersible pressure gauges are required on all primary cylinders 

4. Buoyancy compensator device(s) (BCD) adequate for equipment configuration 

5. Line cutting device 

6. Jon-line and other rigging lines as dictated by site conditions 

7. Ascent reel with lift bag /surface marker buoy 

a. Adequate for maximum planned depth 

b. Minimum of 12 kg / 25 lb lift bag 

8. Oxygen (O2) analyzer; may be supplied by the instructor 

9. Exposure suit adequate for the open water environment 

10. Underwater slate
