TDI Intro to Tech Diving

   The TDI Intro to Tech Course is an introductory course that expands on  recreational training by improving dive planning methods, in-water  skills, and streamlining existing gear configurations in a controlled  and fun learning environment.

Intro to Tech Diving



The TDI Intro to Tech course introduces students to the world of technical diving. This course is designed 

as an introductory course to the TDI Advanced Nitrox course and

the TDI Decompression Procedures Course. 

TDI Nitrox Diver


 TDI Nitrox Diver Course is an entry level course for divers wishing to  continue their diver education and utilize enriched air nitrox as a  breathing gas to extend no decompression limits at depth. 

CSA Scientific Diving Course



TDI Advanced Nitrox Diver


 Are you looking to expand your dive time? Maybe you’re a scientific  diver or photographer looking to stay in the water a little longer?The  TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox  from EAN 21 through EAN 100 percent within your current certification  level to a maximum depth of 40 metres/130 feet during dives that 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. TDI Advanced Nitrox is also a must for  SCR or CCR divers. 

TDI Decompression Procedures


 Are you finding your no- decompression limits (NDLs) a limiting factor  to dives? Do you have to ascend sooner than you would like? As sport  divers, planned decompression is not something that we do or have been  taught.The TDI Decompression Procedures Course prepares you for planned  staged decompression diving. With a maximum operating depth of 45  metres/150 feet, this course is your first step beyond the normal sport  diving limits. 

TDI Trimix Diver


 Are you looking to expand your depth range? Do you want to reduce  narcosis during deep dives? The TDI Trimix Diver Course could be your  next step! As your motivation to explore progresses, you will find that  you may want to go deeper to dive that wreck that is part of history or  that cave system that you have read so much about. One of the major  limiting factors of going deeper is narcosis; TDI’s Trimix Diver course  shows how to minimize the effects of narcosis by adding helium to offset  the nitrogen in your breathing gas.
