Extended Range Diving in Thailand

Technical diver training completed in the Gulf of Thailand

Koh Tao, Thailand –

Big Blue Tech celebrates the graduation of Magnus Baer form a TDI Extended Range course after completing his final 4 training dives on our wreck the “Big Blue Wreck” which is a sunken ferry discovered earlier this month.

Over the last 4 training dives we cleaned up the wreck removing obstacles and fishing nets to make it more attractive and safer for divers to penetrate and enjoy in the future. Not only were the tasks challenging it was also a great chance for Magnus to experience working underwater and keeping track of his environment and responsibility as the dive progressed.

The TDI Extended Range course is the pinnacle of deep air diving where the technical diver learns to explore to a depth of 55m using mixes of oxygen to handle the decompression stops.

Certain areas of the world provide spectacular dives at depths deeper than 39m/130 feet but you will not have access (or very limited access) to helium. The TDI Extended Range course teaches you the proper techniques for utilizing compressed air as a breathing gas and with a maximum depth of 55m/180 feet you won’t have to miss those dives. The Extended Range course will cover topics and skills such as

  • Equipment requirements and configuration
  • Decompression options
  • Use of surface marker buoys
  • Buddy rescue
  • Narcosis checks and management

Although this is the end of the course it’s not the end of his diving and will continue to join us on trips and expeditions in the future to gain valuable experience as a certified technical diver which is essential after certification.
