TDI – Advanced Nitrox Diver Course The objective of this course is to train divers in the benefits, hazards and proper procedures for utilizing EAN-21% through 100% oxygen for dives not requiring staged decompression to a depth of 40m. All of our training dives are conducted in sea conditions using hard boats. The course is normally run in relaxed manner over 3 days. The first day is dedicated to academics and the remaining two days for diving. 4 training dives are required with a minimum accumulated bottom time of 100 minutes.   The course fee includes all Instructor expenses, TDI Advanced Nitrox Manual and TDI certification fees. If extra training dives are required a separate fee will be charged. Boat fees and gas fills are not included.   To enrol or get any further information call us or send us an email.   Together with TDI Decompression Procedures course the candidate would meet the pre-requisites for TDI Trimix course.   TDI Decompression Procedures Course can be combined with this course. See 2-in-1 package: TDI Advanced Nitrox + Deco.
