General Information Technical Diving

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.

Advanced Nitrox Diver

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

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.

Decompression Procedures Diver

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

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)

Semi-Closed Rebreather Diver (Dolphin, Ray, Azmuth)

The TDI Semi-Closed Circuit Rebreather course is the ideal course for photographers, cold water divers or anybody wishing to enjoy a quieter dive and closer interaction with marine life. The course is unit specific covering the Dolphin, Ray, Submatix ST100 and the Azimuth. The SCR course topics and skills include

The TDI Introduction to Semi-Closed Circuit Rebreathers manual takes you through a step by step process of the history and theory of SCR’s, how the units work, and provides setup and cleaning check lists. Your Instructor may also use the Nitrox & Rebreather Equation software which helps calculate inspired gas and MOD.
