Deep diving has different meanings depending on the context. Even in recreational diving the meaning may vary:
In recreational diving, a depth below about 30 metres (98 ft) , where nitrogen narcosis becomes a significant hazard for some divers, may be considered a "deep dive".
For some recreational diving agencies, Deep diving , or Deep diver may be a certification awarded to divers that have been trained to dive to a specified depth range, generally deeper than 30 metres (98 ft) . However, the Professional Association of Diving Instructors (PADI) defines anything from 18 metres (60 ft) to 30 metres (100 ft) as a "deep dive" in the context of recreational diving (other diving organisations vary), and considers deep diving a form of technical diving .
