SDI/TDI is unique in that it offers not one, but two distinct entry-level Nitrox Diver courses.
- The SDI Computer Nitrox course is aimed purely at recreational divers. It assumes students will remain within recreational depth and time limits and use a computer to track their exposure to both oxygen and nitrogen.
- The TDI Understanding Nitrox course, on the other hand, goes into much greater depth in terms of math and physics. Students learn to calculate PO2, MOD and EAD, and do “CNS Clock” calculations. Students who take this course will be much better prepared to go on to cave or technical diving.
It is by taking this course that SDI Instructors become TDI Instructors. It is the prerequisite for further TDI Instructor certifications. Because instructors must already be certified Nitrox Divers, there is no in-water work associated with this program.
The course consists of two parts:
- Self-study, using the TDI Understanding Nitrox eLearning course.
- A one-on-one instructor orientation with a qualified Instructor Trainer.
We frequently combine this course with our SDI/TDI Instructor crossover.
- Be an SDI Instructor in Active status.
- Be certified as a Nitrox Diver.
- Have logged at least ten Nitrox dives.
This program generally takes a morning, afternoon or evening. With sufficient notice, we can generally conduct this program when and where it is most convenient.
We usually conduct this course either at our office in Gainesville, Florida, or in the classroom at Blue Grotto Dive Resort in Williston, Florida.
The cost of this program includes:
- All instruction
- TDI Nitrox eLearning course
- TDI Nitrox Instructor registration fee
There may be additional savings if you take this course in conjunction with one of our other instructor training programs.
