Advanced Nitrox

The Advanced Nitrox course picks up where the recreational Nitrox course leaves off. It is the first real step into technical diving, allowing you to use gas mixes containing more than 40% oxygen. This can allow you to expand your dive time. More dive time means more fun time.

Minimum Exit Requirements
  • Satisfactorily complete the TDI Advanced Nitrox course and written examination

  • Complete all open water requirements safely and efficiently

  • Demonstrate mature, sound judgment concerning dive planning and execution

Advanced Nitrox 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

What You Will Learn
What's in it For You
  • 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 enroll in TDI Decompression Procedures, TDI Semi-closed Rebreather courses, TDI Closed Circuit rebreather courses

The Ocean Pro Difference 

Custom Training

When we get into tech diving, courses become more of a mentorship than a black and white course. We don't believe in just meeting minimum standards, we want to build you into the best you can be. Because of this, we've added extra to our tech  courses, and don't have a set schedule. The schedule and requirements will be discussed in our first classroom session, so we can build a path to success for your specific needs.

Rent to Own

At this level of diving, you generally want to own your own gear. However as we add new gear that you may never have used before it can be hard to know what you want to buy. That's why we have our Rent to Own program. Rent a piece of gear, and if you decide that's what you want to buy, your rental price goes towards the cost of the gear!


  • Minimum age 18

  • Minimum certification of Nitrox Diver and Advanced Open Water

  • Proof of 30 logged open water dives, at least 15 in a drysuit, at least 6 within the past 6 month, and at least 5 using nitrox

Your Next Adventure

Once you've finished your Advanced Nitrox course, the next step in your tech diving path is the Decompression Procedures course!
