The TDI Nitrox Diver course at Get-N-Wet Scuba is built for open water divers who want to learn more about nitrox mixtures, extend their bottom time, or start moving toward technical diving education. You'll cover the benefits, hazards, and proper procedures for using nitrox mixes from 22 through 40 percent oxygen content, along with equipment considerations, cylinder labeling, mixture analysis, and gas blending procedures.

Once certified, you'll be able to dive using EAN-22 through EAN-40 without direct supervision, and you'll unlock eligibility for further TDI training like Advanced Nitrox, Decompression Procedures, and Semi-closed Rebreather courses. To complete the course, you'll demonstrate understanding of Equivalent Air Depth (EAD) calculations, perform oxygen analysis on nitrox mixtures, and pass the TDI Nitrox written examination. The course is available entirely online, so you can start eLearning right away.
