Advanced Nitrox Diver Course

Learn to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression.

During your Advanced Nitrox Diver Course, you will learn how to safely use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression
This 2-3 day course will allow you to spend more time underwater exploring the exciting world underwater.  
The course consists of home study online theory, Classroom session, Confined water session and Open water dives.
All courses that are taught through Sam Bennett Diving have a ratio of 4:1 (students to instructor)
    Prerequisites:
    • Minimum age 18, 15 with parental consent
    • Minimum certification of TDI Nitrox Diver or equivalent
    • Proof of 25 logged open water dives
    What you get out of this course:
    • Ability to dive using EAN 21 through 100 percent oxygen provided:
      • The diving activities approximate those of training
      • The areas of activities approximate those of training
      • Environmental conditions approximate those of training
    • Ability to enrol in TDI Decompression Procedures, TDI Semi-closed Rebreather courses, TDI Closed Circuit rebreather courses

    Land Skills

    • Review of nitrox skills
    • Demonstrate correct use of oxygen analyzer including the optimal procedure for calibration
    • Demonstrate adequate pre-dive planning:
      • a. Limits based on personal gas consumption.
      • b. Limits based on oxygen exposures at planned depth with actual mix
      • c. Limits based on nitrogen absorption at planned depth with actual mix
    • Calculate and log CNS loading for each dive including cumulative exposure where appropriate
    • Demonstrate understanding of gas labelling
    • Demonstrate adherence to conventions regarding the prep of equipment for oxygen (O₂) service
    • Program nitrox computer with appropriate oxygen percentage if used
    • Properly execute the planned dive within all predetermined limits

    IN-water skills

    • Demonstrate buoyancy control; ability to hover at a fixed position in water column without moving hands or feet
    • Show good awareness of buddy and other team members through communications, proximity and team oriented dive practices
    • Demonstrate ability to manage free flow from primary regulator in a controlled fashion, shutdown cycle, and switch to back-up regulator
    • Conduct appropriate safety stop while maintaining neutral buoyancy
    • Demonstrate 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
