Nitrox Courses

What is nitrox?
“Nitrox” is the diver slang for “Enriched Air Nitrox.” It is air that has had oxygen added to it. Normally we breath air which is 21% oxygen and 79% nitrogen. Nitrox can be anything from 22% oxygen and 78% nitrogen to 40% oxygen and 60% nitrogen.

Why use it?
The benifit of nitrox is that if you are diving with less nitrogen in your tank, then you absorb less nitrogen into your system, allowing you to:

  1. Increase your bottom time dramatically,
  2. Decrease your surface interval in between your dives,
  3. and increase the safety margins of no decompression time.
  4. Many also say they “feel better” and “less sleepy” after diving with nitrox due to the increased oxygen content.
  5. Is it especially recommended for divers that make multiple dives daily, are overweight, or over 40 years old.

How can I use nitrox?
To use nitrox you need to get your Enriched Air Nitrox Specialty. You can do this with or without diving.

Option 1 (without diving): Go online and sign up and complete the theory through PADI eLearning. Then, do some quick paper work with Octopus Diving, analyze some nitrox tanks and get your photo taken. Cost $210 for PADI eLearning, $50 to Octopus Diving.

Option 1 (with diving): Same as above, except with two dives on 32% nitrox. Cost $210 for PADI eLearning, $160 to Octopus Diving.

Option 2 (without diving): Buy the Enriched Air Specialty manual from Octopus Diving, read the book and answer the questions, go over some theory with an Octopus Diving Instructor, take an exam, analyze some nitrox tanks, get your photo taken. Cost: $50 for manual, $100 to Octopus Diving.

Option 2 (with diving): Same as above, but with two dives on 32% nitrox. Cost: $50 for manual, $250 to Octopus Diving.
