SNSI Decompression Procedures Course

Are you finding your No Decompression Limits (NDLS) a limiting factor for your dives? Do you have to get up earlier than you'd like? Like recreational divers, planned decompression is not something we do or have been taught. The SNSI Decompression Procedures course prepares you to plan and perform decompression dives. With a maximum depth of 45 meters / 150 feet, this course is the first step beyond the normal confines of recreational diving. The SNSI Decompression Procedures course can be combined with the SNSI Advanced Nitrox course and form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to advance to additional technical levels.

This course is for:

• The advanced diver looking to expand their knowledge of decompression theory and diving techniques.
• The certified advanced diver who is interested in extending their bottom time.
• The certified advanced diver who is interested in furthering technical diving education.

Course prerequisites:

• minimum age of 18 years.
• minimum certification of SNSI Advanced Adventures, SNSI Advanced Diver, or equivalent.
• Proof of 25 logged open water dives.

What you can expect to learn:

• Decompression dive planning, including:
  • Decompression gas choices
  • Tables vs. dive computers
  • Emergency and contingency plans (equipment failure, omitted decompression, etc.)
  • decompression procedures
  • equipment selection
  • pre-dive checks and skills
• Stress analysis and mitigation
  • Following a decompression schedule
  • gas change
  • Staff awareness and communication
• SMB / lifting bag launch
• Proper trim, buoyancy and swimming techniques
• Emergency procedures (equipment failures, catastrophic outgassing, omitted decompression, navigation errors, etc.)
• Equipment considerations, cylinder labeling, analysis of nitrox mixtures, and gas mixing procedures

What's there for you?

• Ability to perform diving decompression activities without direct supervision, provided that:
  • Diving activities approach those of training
  • Areas of activities approximate those of training
  • Environmental conditions approximate those of training
• Ability to enroll in SNSI Advanced Nitrox, SNSI Extended Range, SNSI Advanced Wreck, SNSI Trimix courses.

SNSI Decompression Procedures Diver Certification Requirements:

• Satisfactorily complete the SNSI Decompression Procedures exam.
• Fulfill all on-water requirements safely and efficiently.
