Valentines Tech Expedition: Advanced Nitrox Diving

Advanced nitrox divers graduate with bull sharks in Thailand

Koh Tao, Thailand – Big Blue Tech celebrates the graduation of Yvonne Fries, Helen Artal, Thomas Hallstrom and Duncan Tyler from a TDI Advanced Nitrox course conducted by TDI Instructor James Thornton-Allan and assisted by Andrew Cavell and Ash Dunn over various dive sites on Koh Tao Island in Thailand.

The TDI Advanced Nitrox course is designed to orientate the student about rich or high mixes of oxygen and their advantages while wearing technical diving gear. The use of low mixes to advance deep diving and the use of high mixes to add extra conservatism to optional stops during the dive.

The students learned about carrying a decompression cylinder, oxygen handling and analysis and vairous other skills. The final dives were conducted using nitrox to allow the diver to flow through a no-decompression schedule switching to different mixes of nitrox the shallower the dive went. This course certifies the diver to delve to 40m using up to 100% oxygen depending on the depth and if the situation is warranted.

The final dive was also held at Chmphon Pinnacle where we were met by Bull Sharks that live at that dive site creating an exciting atmosphere for learning and diving.

The students were issued certification after and exam and progress on to their TDI Decompression Procedures course tomorrow with a return to Chumphon Pinnacle for some more dive time with the sharks. You can read more about the Advanced Nitrox course here: TDI Advanced Nitrox Diver Course
