Advanced Nitrox
The Advanced Nitrox Diver course prepares students for exposure to gas mixtures with oxygen concentrations in excess of 40 percent. This includes:
- Open-circuit technical divers using pure oxygen or oxygen-rich gas mixtures for decompression.
- CCR divers who typically have high concentrations of oxygen in their breathing loops when in shallow water.
Most open-circuit students take this course in tandem with the Decompression Procedures course. You can sign up in person, over the phone or online by clicking the button below. If you sign up online, you will still need to call to schedule your class.
This program generally takes at least two days and four dives. With sufficient notice, we can usually offer this course when it’s most convenient for you.
- Be at least 15 years old
- Possess entry-level Nitrox certification
- Be certified to at least the Rescue Diver level.
- Be able to answer No to all the questions on the medical history questionnaire or obtain a physician’s approval for diving.
$275/person includes:
- All instruction (eLearning course fee is additional)
- Certification processing when earned
You supply:
- Mask
- Adjustable scuba fins
- Adequate exposure protection for depth and water temperature
- Backmounted doubles with isolation manifold
- Backplate or dual-cylinder harness and air cell
- Two regulator first stages, each with its own second stagte
- At least one decompression cylinder
- Mission-capable dive computer(s)
- Underwater compass
- Dive knife/cutting tool(s)
- Primary and backup dive lights
- SMB and reel or spool
Be aware that equipment for technical diving must meet some very specific requirements. Do not make any equipment purchases before first consulting with your instructor.
Students are also responsible for gas fills and boat fees or dive site admission.
Consider this:
- In technical diving, divers routinely use pure oxygen or oxygen-rich gas mixtures for decompression.
- Rebreather divers in shallow water often have a gas mixture with ab O2 concentration in excess of 40 percent in the breathing loop.
- The catch is, your entry-level Nitrox diver training did not cover the use of gas mixtures with oxygen concentrations in excess of 40 percent.
- Exposure to high concentrations of oxygen at depth carries a high risk of oxygen toxicity. Handling such gasses on the surface also presents an increased risk of fire or explosion.
This is why we have the Advanced Nitrox Diver course. It prepares divers to use pure oxygen or oxygen-rich gas mixtures.
Most students take this course in tandem with one or two others, most notably Decompression Procedures.
In this course, the skills we cover include:
- Correctly read and mark Nitrox cylinder
- Correctly program a Nitrox Computer
- Determine Adjusted NDLs using a Nitrox computer
- Use a formula to calculate depth in ATA
- Use a formula to calculate MOD
- Use a formula to calculate PO2
- Use a formula to calculate EAD
- Calculate depth in atmospheres by using a formula
- Plan a repetitive non-decompression dive
Most importantly, we don’t practice these skills until you finally get them right. We have you repeat them until you can’t do them wrong.
