SDI Computer Nitrox (Classroom-Based)

Extend your bottom time by learning how to safely breathe gas mixtures containing up to 40% oxygen. 

The classroom-based SDI Computer Nitrox class will cover both the history and theory behind nitrox diving and include a practical exercise in which you'll calibrate an oxygen analyzer, analyze a tank, label the tank, and fill out a sample nitrox log. You'll understand how oxygen mixtures work to extend bottom times along with the limits of nitrox diving and how to avoid the risk of oxygen toxicity. 

The class includes e-Learning which must be completed prior to the classroom session. Upon completion of the course, you'll receive a digital certification card. 

Who this course is for:

  • The certified diver looking to advance their knowledge and skill set
  • The certified diver looking to extend their no decompression time limits

Course prerequisites:

  • Minimum age 18, 10 with parental consent
  • SDI Open Water Scuba Diver, SDI Junior Open Water Scuba Diver, or equivalent, or current enrollment in one of those courses
