Technical Diving Training

What is Technical Diving? (sometimes referred to as Tec diving)

A form of scuba diving that exceeds the scope of recreational diving (although the vast majority of technical divers dive for recreation and nothing else). Technical divers require advanced training, extensive experience, specialized equipment and often breathe breathing gases other than air or standard nitrox.

There is some level of professional disagreement as to what the term should encompass. It was not that many years ago that NITROX diving was considered "technical"; however today NITROX is not normally considered technical. The definition of technical diving is generally accepted as

..."diving other than conventional commercial or recreational diving that takes divers beyond recreational diving limits. It is further defined as an activity that includes one or more of the following: diving beyond 40 meters/130 feet, required stage decompression, diving in an overhead environment beyond 40 linear metres from the surface, accelerated stage decompression and/or the use of multiple gas mixtures in a single dive.".

The following table tries to set out the broad indicative parameters of what is normally regarded as technical rather than recreational diving.
