Why TDI

padi

TDI is the largest technical certification agency in the world.  As one of the first agencies to provide training in mixed gas diving and rebreathers, TDI is seen as an innovator of new diving techniques and programs which previously were not available to the general public.  Training with TDI has provided divers with the opportunity to see such wrecks as the Andrea Doria, Luisitania and the Prince of Wales.  TDI divers have explored underwater caves in Spain, Australia and Mexico and assisted as support divers on world record freedives done in the Red Sea.

TDI’s professionals are held to the highest standard to ensure quality training throughout the world.  This means that as a diver taking a TDI course, your instructor will have documented his experience and knowledge prior to achieving that rating.  As an instructor candidate taking a TDI course, your TDI instructor trainer will have gone through the paces to achieve the highest level of training that TDI offers.

TDI is committed to offering the highest quality training supported by the latest materials with the most up to date information and techniques.  TDI’s materials are written by authors that acutely conduct the type of diving they are writing about.  Those same materials are update as technology and equipment change. 

General Information about TDI Training

Now that you are already open water certified and your looking for little more adventure, technical diving may be just the thing for you.

Question: What is technical diving?

Answer; All non commercial diving is categorized as recreational and within recreational diving there is sport and technical.  Sport diving includes your open water certification, advanced scuba diver, and many other specialty course.  Technical diving picks up where sport diving ends generally at nitrox (a breathing gas with oxygen levels greater than 21 percent). 

Question: What is my first step into technical diving?

Answer; Nitrox is most divers first step into technical but it has also become very popular amongst sport divers so TDI Advanced Nitrox and Decompression Procedures would be a great start.  Advanced Nitrox and Decompression Procedures for the foundation of technical diving all other course will build on the knowledge and skills learned during these courses. 

Question: Do I have to go deep for technical diving?

Answer; No. Although technical diving is commonly thought of as deep, there are a lot of courses that stay within the sport diving limits (40 m / 130 feet) such as Advanced Nitrox, Semi Closed Circuit Rebreather (SCR) and Closed Circuit Rebreather (CCR) and Advanced Wreck to name a few.

Question: Will technical diving allow me to go deeper?

Answer; yes.  TDI has course curriculums that take you as deep as 100 m / 330 feet and do so in a manner that each course builds on the last and each course takes you a little deeper.  By receiving training in this manner not only are your skills and knowledge increasing but so is your comfort level.

TDI Technical Dive Courses

TDI Intro To Tech-
The TDI Intro to Tech course is the perfect course for divers who have heard about technical diving and want to find out more about this exciting branch of advanced recreational diving. This course walks students through the special techniques, planning procedures and skills that set technical diving apart from traditional sport diving. It will show them how to improve their dive planning methods, in-water skills and streamline their existing gear configuration, in a non-threatening and fun learning environment. The specific skills this course will highlight are:
  • Advanced Buoyancy Control
  • Gas Management
  • Situational Awareness
  • Trim
  • Gear Configuration and Selection
  • Many More!
TDI’s Intro to Tech course is a useful stand-alone course for the diver who wants to become a more skilled, more proficient diver regardless of if he intends to move on to technical diving. The course may also be used as an introduction to the TDI Advanced Nitrox course and the TDI Decompression Procedures course. And finally, it is also a good refresher for certified technical divers who may want to refresh their skills or have them re-evaluated by a TDI technical instructor. Email


TDI Decompression Procedures

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 45m/150 feet, this course is your first step beyond the normal sport diving limits. Your TDI Instructor will provide you with valuable information and skills, among the topics covered are
  • Kit set-up
  • Equipment requirements
  • Decompression techniques
  • Decompression breathing gases
  • Gas management
  • Contingency planning
The TDI Decompressions Procedures course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses.  After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels. Some of the materials you will be using include the TDI Divers Guide to Decompression Procedures, US Navy or Buhlmann Air Decompression Tables (made of vinyl for easy in-water use and storage)

TDI Advanced Nitrox
-
Tec 45 takes your training as a Tec diver further and deeper. It is the second sub-course in the full PADI Tec Diver course. Learning the skills, equipment and planning needed to dive to a maximum of 45 metres. You will acquire the knowledge to plan and execute single and repetitive decompression dives using a single stage cylinder of EANx or oxygen to accelerate or add conservatism to the decompression stops. Email


TDI Advanced Nitrox
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.

TDI KISS Mixed Gas Dilunet CCR Diver

The TDI KISS Mixed Gas (Classic and Sport) course is your next step into closed circuit rebreather diving and with the addition of helium as a diluent gas, it is your opportunity to explore a little deeper. Using the latest in technology CCR’s maximize your gas supply and provide the optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen (PPO2). During the dives (minimum of six) your TDI Instructor will teach you all the nesscery skills to conduct CCR dives utilizing helium as a diluent gas and oxygen levels as low as 16 percent to a maximum depth of 60 m / 200 feet for the KISS Classic and 50 m / 165 feet for the KISS Sport, the skills include.
  • Calculating off-board gas requirements
  • Recovering from system failure
  • Calibration of electronics
  • Emergency procedures
  • Removing and replacing off-board gases
  • Surface marker buoy deployment
The TDI KISS Closed Circuit Rebreather manual provides comprehensive information about the units and how they operate during a dive, this combined with the TDI Trimix Diver manual complete the academic knowledge needed to conduct mixed gas CCR Email
