When you look at how far diving has come in so short a time span...all diving is technical. Every dive we do is a deco dive. For the most part aside from 'payed' commercial/scientific/military and a few other areas of diving... what we all think as technical diving is better termed 'recreational technical' diving....we do it as a sport and recreation, regardless if its cave/penetration wreck or deep o/w. All rec. technical divers started at the beginning in an o/w type course. The really important thing for divers to remember is that we are all scuba divers.
