Advanced Nitrox Course with Sharks and Whales in Thailand
This morning Big Blue Tech, a technical scuba diving school, started a TDI Advanced Nitrox course on Koh Tao, Thailand. This course runs over 2 days and exposes divers to the use of nitrox to 40m and up to pure oxygen. Today the course was attended by Andy Cavell and Mark Slinn along with Ash Dunn and Emily Billingham.
The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 to a depth of 40 metres/130 feet during dives hat do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. Advanced Nitrox is also a great course for those wanting to extend their bottom times in shallower depths such as scientific diver, and a must for SCR or CCR divers. The course cover topics like, Equipment requirement, Dive planning, Oxygen tracking, Blending methods.
You will use the TDI Advanced Nitrox Diving manual for your course, which explains in an easy to understand practical manner the complex information that Advanced Nitrox divers need to know.
The course began this morning with a dive to Chumphon Pinnacle, one of Koh Tao’s deep and best dive sites. Since the divers had experience in technical diving gear we were able to begin the dives deeper than normally. Emily had joined us to test out new equipment before joining the January expedition.
The divers had various skills to perform but we distracted by the appearence of over 20 sharks and a minke whale. Only the technical divers saw the minke whale underwater but everyone saw it on the surface as the whale cressed to show all everyone he was there.
After the two dives Andy said ” That was cracking like ” , “I’m well chuffed me”; for those that don’t speak northern english he said “What a wonderful dive i just had, i am very happy with the experience”.
The divers had drifted a considerable distance on their lift bags which attracted the large mamall who swap within touching disance of the divers. On the second dive of the morning the divers were again distracted by the swarms of bull sharks who were feeding on the abundant schools of fish. These sharks have never been interested in dives (knock on wood) and just circle around keeping a safe distance from the divers whom teh sharks are afraid of.
The divers performed really well despite all the action, unfortunately not all the same experiences can be shared by all. This week alone we have seen solo diving with shale sharks, simulated decompression with a whale and gas switching with sharks.
The course still requires an additional 2 dives which will be completed the following day.
Just a reminder, we accept new courses starting in February but spaces are filling quickly leading up till May.
