The PADI Tec Basics course is intended to be the stepping stone from recreational to technical diving.
The PADI Tec Basics course runs within recreational limits, using segments from PADI Tec 40 Dives 1 and 2. The course allows PADI Tec Deep Instructors to have students practice fundamental tec skills before enrolling in the PADI Tec 40 program.
The PADI Tec Basics course clearly informs divers that the PADI TecRec program address technical diving apart from mainstream recreational diving. These two general diving modes are defined:
Recreational scuba diving is no stop diving with air or enriched air nitrox to a maximum depth of 40 metres/130 feet, and during penetration dives, within the natural light zone and no more than a total linear distance of 40 metres/130 feet from the surface. It is primarily open-circuit diving, but includes recreational eCCR and eSCR rebreathers (Type R).
Technical scuba diving is diving other than commercial or research diving that takes divers beyond recreational limits. It is further defined as and includes one or more of the following: diving beyond 40 metres/130 feet, required stage decompression, diving in an overhead environment beyond 40 linear metres/130 linear feet from the surface, accelerated decompression, and the use of variable gas mixtures. Technical diving uses extensive methodologies, technologies and training to manage added risks associated with it. Typically, this means using complex or highly specialized equipment in situations where direct access to the surface is inaccessible due to a ceiling imposed by decompression or by a physical barrier such as found inside cave or wreck diving environments.
