Learn to dive with oxygen-enriched air, also known as nitrox! NItrox is one of the must-have diving certifications for a recreational or budding technical diver. Using nitrox can shorten your surface intervals, and extend your no-decompression limits.

You have a variety of choices for this course (more on that in the FAQ below) but, in each class, you’ll gain knowledge and skill sets appropriate for using nitrox mixes up to 40%, as well as the physiological effects of different breathing gas mixtures and equipment considerations for using nitrox. Our classes discuss the advantages and disadvantages of using nitrox, analyzing your tanks, and managing your oxygen exposure.

At the end of the course, you’ll get all the benefits of diving nitrox including, increased safety margins, reduced post-dive fatigue and you’ll be able to extend your no-decompression times. If you take the PADI course, you can also earn college credit!

Frequently Asked Questions

Q: Is there a difference between the courses?
A: Yes. The TDI and PADI courses are more comprehensive. You’ll learn how to use tables and the TDI Nitrox course is the introductory course for TDI’s Advanced Nitrox course, which is your entry into technical diving training. Our TDI course is technical training and will be the most comprehensive training.

Q: Will the TDI course allow me to conduct technical dives?
A: No. This is the foundation course for further training, but you will not be trained to dive deeper or conduct dives outside of recreational limits.
