Advanced Nitrox

Are you looking to expand your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water a little longer? The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 130ft/40m during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. TDI Advanced Nitrox is also a must for SCR or CCR divers.

PREREQUISITES (MUST BE MADE PRIOR TO THE START OF THE COURSE)

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

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
  • 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

Decompression Procedures

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 150ft/45m, 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.

PREREQUISITES

  • Minimum age 18
  • Minimum certification of SDI Advanced Adventure Diver, 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. 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
  • Ability to conduct decompression diving activities without direct supervision provided:
    • The diving activities approximate those of training

TDI Trimix Diver

Are you looking to expand your depth range? Do you want to reduce narcosis during deep dives? The TDI Trimix Diver Course could be your next step! As your motivation to explore progresses, you will find that you may want to go deeper to dive that wreck that is part of history or that cave system that you have read so much about. One of the major limiting factors of going deeper is narcosis; TDI’s Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. While taking the Trimix Diver course your TDI Instructor will teach you how to plan and execute dives utilizing as little as 18% oxygen and diving to maximum depth of 200ft/60m with a blend of helium appropriate for the planned depth.
