• The certified 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 has interest in moving forward with technical diving education

Course prerequisites

(these requirements must be met prior to the start of the course):

• Minimum age 18, 15 with parental consent
• Minimum certification of TDI Nitrox Diver or equivalent
• Minimum certification of SDI Advanced Adventure Diver, Advanced Diver, or equivalent
• Proof of 25 logged open water dives

Required Equipment :

• You will need a Tech Dive Computer able to switch to 3 gases
• You will need to own a tech setup or rent one from the store. (If you would like to purchase a set up come in and talk to our staff)

What you can expect to learn:

Advanced Nitrox picks up where TDI Nitrox leaves off and offers a more in-depth look at diving with nitrox including:

• Physics and physiology relating to diving with gas mixes containing more than 40% oxygen
• Gas planning, dive tables, dive computers, oxygen limitations, nitrogen limitations
• Equipment considerations, cylinder labeling, analyzing nitrox mixtures, gas blending procedures, and oxygen service ratings for using gases with more than 40% oxygen
• 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

Some of the skills you will complete in this course include:

• Demonstrate buoyancy control; ability to hover at fixed position in water column without moving hands or feet
• Show good awareness of buddy and other team members through communication, proximity, and team oriented dive practices
• Demonstrate the ability to manage free flow from primary regulator in controlled fashion, shut down cycle, and switch to back up regulator
• Conduct appropriate safety stop while maintaining neutral buoyancy
• Demonstrate the ability to share air with buddy as both recipient and donor in a controlled manner while maintaining position in the water column
• Demonstrate correct body position; appropriate trim, such as horizontal/streamlined when moving forward
• Demonstrate proper stress analysis with self and dive buddy
