PADI Tec Basics 

Course Overview


The PADI Tec Basics course is a bridge from recreational to technical diving. It exposes recreational divers to tec
diving and entry level tec diving skills and equips them with the information they need to decide whether or not to
accept the additional risk and commitment that PADI Tec courses demand. 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 course also
recognizes students who choose not to continue their technical training.


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 (other than the automatic variation
of a Type R rebreather) during a dive.


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.


Divers usually tec dive for the challenge and fun rather than as a profession, so it is a recreation (hence the name
“TecRec” for these programs). However, to avoid confusion regarding the limits and scopes, tec diving is not called
“recreational diving.” The courses in the PADI TecRec program directly address the more demanding and
challenging nature of technical diving, which involves more hazards and inherent risks than recreational diving.
All the TecRec CCR courses are built upon mainstream instructional system design principles for which PADI
courses are known.


Technical diving is not for everyone. It should not be presented as a goal for all divers to aspire to. Rather, it is
for a growing but smaller segment of divers who are looking for challenge, and who are willing to accept the
costs, risks, time commitment, training and physical fitness requirements necessary. In the face of these, it may
be perfectly appropriate to remind those who may not be suited to TecRec that they can enjoy a lifetime of novel
adventures without ever leaving recreational limits.


Diver Prerequisites
1.  PADI Advanced Open Water Diver or qualifying certification. PADI Rescue Diver is recommended.


Student Equipment Requirements
1. Twin cylinders with dual manifold and isolator or independent cylinders in a sidemount configuration
2. Primary and secondary regulators – primary regulator must have seven foot/two meter hose for air
sharing.
3. SPG. In sidemount configuration both regulators must have SPGs.
4. Harness with shoulder and hip D‐rings (backmount or sidemount).
5. BCD – wings
6. Stage/deco cylinder with attachment hardware, a single second stage regulator, and SPG. Note: It is
recommended that each diver have and use individual stage/deco cylinders. However, it is acceptable for
students to practice required skills with a shared cylinder. All cylinders must be filled with air only,
simulating higher oxygen content as needed for skill development.
7. Dive computer
8. Appropriate exposure suit
9. Weight System, if required.
10. Reel or spool
11. Knife/cutting device
12. Slate
13. Compass
14. Lift bag or DSMB
