Technical diving (also thought of as tec diving or technician diving) is diving which surpasses the agency-specified constraints of recreational diving to get nonprofessional purposes. Technical diving might possibly expose the diver to threats outside those involved with diving, also also to chance of injury or death. Appropriate abilities, experience and knowledge, and employing suitable equipment and procedures may reduce the danger. The relevant skills might be developed through experience and training. The gear involves breathing gas sources, and gases aside from standard or air nitrox combinations. The word technical diving was imputed to Michael Menduno, that had been editor of this (now defunct) diving magazine aquaCorps Journal. The style and duration, technical diving, are advents,[note 1] even though divers are doing what’s commonly known as technical diving for years.
The expression technical diving might be traced straight back into the cover story of this first dilemma of”AquaCorps” magazine, in early 1990, branded call it”hightech” Diving by Bill Hamilton, describing the ongoing condition of recreational diving outside the generally accepted constraints, including, profound, de compression and mixed gas diving. By mid 1991, the magazine has been using the word technical diving, being an analogy using an based term technical (rock) rising. From the usa Health Administration and that the Occupational Safety categorises diving that isn’t work-related as diving for purposes of exemption. In addition, this is true in several nations.
|Deep diving||Maximum depth of 40 metres (130 ft) or 50 metres (160 ft)||Beyond 40 metres (130 ft) or 50 metres (160 ft)|
|Decompression diving||Some agencies define recreational diving as “No decompression” diving; others consider all dives to be decompression dives.||Some agencies define technical diving as “Decompression diving”; others consider all dives to be decompression dives.|
|Mixed gas diving||Air and nitrox||Nitrox, trimix, heliox and heliair.|
|Gas switching||Single gas used||May switch between gases to accelerate decompression and/or “travel mixes” to permit descent carrying hypoxic gas mixes|
|Wreck diving||Penetration limited to “light zone” or 30 metres (100 ft) depth + penetration||Deeper penetration|
|Cave diving||Penetration limited to “light zone” or 30 metres (100 ft) depth + penetration||Deeper penetration, may involve complex navigation and decompression.|
|Ice diving||Some recreational agencies regard ice diving as recreational diving||Others regard it as technical diving.|
|Rebreathers||Some agencies regard use of semi-closed rebreathers as recreational diving||PADI TecRec, TDI, GUE, IANTD, SSI XR, IART, ISE, NAUI TEC, PSAI, UTD regard as technical diving.|
