What is technical diving?

Technical scuba diving is diving other than conventional commercial or research diving that takes divers beyond recreational scuba diving limits. It is further defined as and includes one or more of the following:

  • diving beyond 40 metres/130 feet deep
  • completing dives requiring staged decompression
  • diving in overhead environments beyond 40 linear metres/130 linear feet of the surface
  • accelerated decompression and/or the use of variable gas mixtures during the dive

As the surface is effectively inaccessible in an emergency during technical diving, technical divers use extensive specialised methodologies,  technologies and training to minimise the risk at hand. Though this may be the case, technical diving admittedly has more inherent risk, potential hazard and shorter critical error chains than recreational scuba diving.

How long has technical diving been around?

Most people would agree that cave diving is a form of technical diving. Cave diving developed in the late 1960s and 1970s, developing into a discipline largely like it is today by the mid 1980s. In the early 1990s, several groups of divers around the world began experimenting with technologies for deep diving (beyond recreational limits) to explore both caves and wrecks. These communities united and emerged as “technical diving” or “tec diving” with the publication of aquaCorps (no longer in print), which dedicated itself to this type of diving. Since then, tec diving continues to develop both in scope and in its technologies.

Go extreme. Go places where one tank is not enough. Go beyond the recreational limits and explore the underwater world in a safe and responsible way.

Technical diving encompasses areas such as rebreather diving, deep diving, cave diving or exploring the internals of a wreck.

We run all technical diving courses available: Entry level tech courses  – Advanced Nitrox, Decompression Procedures, and Extended Range, Sidemount, Wreck, Trimix, Cave, Rebreather, as well as Advanced Level Technical Courses

The Technical Diving agencies Blue Label Diving uses:

SSI – Scuba Schools International


SSI_LOGO_Horizontal_207_50For more than 40 years, Scuba Schools International SSI has provided training, scuba diving certification, and educational resources for divers, dive instructors, dive centers and resorts around the world. Started in 1970, SSI has expanded to include more than 30 Service Centers, is represented in more than 110 countries with over 2.500 International locations, and has materials printed in more than 30 languages.


SSI is clearly the name to trust in the diving world, and we attribute that success to our uncompromising standards and focused methodology.

Since June 1, 2010, Scuba Schools International SSI is one of the few training agencies who qualified for a Global ISO Certification. 7 SSI Programs, 5 for divers and 2 for instructors, got certified after the International Standards – ISO 11121 for Try Scuba Diving, ISO 28401-1 to -3 for Scuba Diver to Dive Guide, ISO 11107 for Enriched Air Nitrox and 28402-1 and -2 for Dive Control Specialist and Open Water Instructor. Due to that the SSI C-Cards for the appropriate ratings will carry the ISO quality label in the future.

PADI Technical Diving Courses – TecRec

PADI TecRec courses are the PADI range of Technical diving courses.

The changes brought to the program adhere very closely to the industry standards of specific technical diving training agencies and  allow for future crossovers between agencies when possible. What are Technical Diving courses? They are a series of advanced diver training courses to introduce and educate recreational divers about conducting dives beyond the established limits of 40m. Using a single gas, divers can execute no-decompression dives. PADI TecRec offers the possibility for these divers who wish to venture longer or deeper into the aquatic realm by an intense training program.

The program offers step-by-step training allowing the diver to gradually dive deeper whilst executing longer decompression stops; stops are unavoidable when doing deeper exploration dives. During the course you will be introduced to new diving equipment and it’s use, as well as diving procedures, during which time you will be accompanied by a highly skilled PADI TecRec instructor, supported by state of the art educational materials such as books, slates and software.

TDI Technical Diving Courses

As a diver undertaking a TDI Technical Diving Course, you can rest assured that your instructor will have documented his experience and knowledge prior to achieving their Technical Instructor rating.

An important point to note – Blue Label Diving has a special and unique feature for the Technical Diving courses: our Dive Instructors are not restricted to teaching in one specific area; we can come to you if you don’t have the time to travel.

TDI is the largest technical certification agency in the world. As one of the first agencies to give training in mixed gas diving and rebreathers, TDI is seen as an innovator of new diving techniques and programs which before 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 free dives in the Red Sea.

Blue Label Diving & TDI are committed to offering the highest quality training, combined with the latest teaching materials and the most up to date information and techniques. Those same materials are updated as research and technology advances and equipment becomes more. It is important to note that all materials approved for course use by TDI are written by authors that routinely conduct the type of diving they discuss.


RAID is the world’s fastest growing diver training agency with both full service and satellite regional offices, dive stores and instructors waiting to provide diver services to you across the globe. RAID is also the first diver training agency to offer a complete range of online diver academic programs from beginner to instructor examiner levels in snorkeling, scuba and freediving.

RAID Technical programmes are more challenging and develop divers to dive beyond recreational limits and incur decompression obligations.

Building on the life support training already established in the strong RAID foundation programmes they take the diver to the next level based on time in the water and experience at depth.

Technical diving is not a light subject, it demands the diver to acquire a fair amount of diving experience to understand and master conventional diving before attempting decompression and mixed gas environments. There is no quick way to safe technical diving, only time underwater and many hours of practice are some of the requirements to enter these courses.
