What is it?
This course examines the theory, methods and procedures of planned stage decompression diving. It is designed as a stand-alone course or it may be taught in conjunction with Advanced Nitrox . The main objective is to train divers how to plan and conduct a standard staged decompression dive not exceeding the maximum depth of 150 fsw.
What will we do? (Overview)
- Overview of decompression
- Physics
- Physiology
- Decompression Options
- Equipment considerations
- Dive tables vs. Computer
- Dive planning
- Procedures:
Open Water Skills:
- Properly analyze all gas mixtures and label cylinders
- Demonstrate adequate pre-dive planning
- Properly execute the planned dive within all pre-determined limits
- Monitoring of decompression status equipment
- Contingency Situation & Problem Solving
- Correctly deploy a lift bag using a dive reel and/or up-line
- Demonstrate (simulated) emergency gas sharing
- Demonstrate emergency deployment of a backup regulator or bailout scuba system
- Demonstrate the proper deployment, management and use of the bottom mix
- Demonstrate buoyancy control and awareness throughout the dive.
How long will it take?
- Classroom/Briefings- Approximately 3+ hours
- Open water dives- 4 (with a minimum accumulated bottom time of 100 minutes).
Prerequisites:
- Minimum age is 18
- 25 logged dives or the equivalent at the discretion of the instructor, in the environment in which the course is being presented
- The instructor has final approval authority on accepting anyone into the class even though minimum prerequisites have been met.
- Nitrox recommended
Equipment Needed:
- Primary cylinders- volume appropriate for planned dive and gas consumption with reserve gas (Doubles recommended)
- Decompression Mix Cylinders- volume appropriate for the planned dive and student gas consumption with gas reserve. SPG’s required on stage cylinder/regs. Cylinders labeled in accordance with TDI standards
- Primary and back up depth gauge and automatic bottom timer and/or dive computer. Regulators-
- Primary and alternate second stage required on all primary cylinders. SPG’s are required on all cylinders
- BCD adequate for equipment configuration
- Jon-line and other rigging lines as dictated by site conditions
- Reel/spool with lift bag/surface marker buoy. Line on reel adequate for planned depth. Minimum 50lb lift bag
- Exposure suit adequate for maximum planned depth
- Cutting Device
- O2 analyzer (may be supplied by the instructor)
- Underwater slate
***If using doubles/twin tank kits: isolator manifold with two regulators. 7′ hose to be on the primary regulator. DIN valve manifolds preferred
