Diver Training

Not only is the underwater environment Hazardous but diving equipment can be dangerous when used by the untrained; there are many unexpected problems that the new diver must be taught to avoid. Also, beginners need practice and a gradual increase in experience to build their confidence in their equipment and themselves, to develop the skills needed to control the equipment and to respond safely when they encounter difficulties.

Most commercial operators and dive clubs serving divers insist that each diver is able to show them "certification", evidence of a minimum level of training, for the type of diving the diver intends to do. Reputable dive operators, dive shops and compressor operators refuse to allow uncertified people to dive, hire Diving Equipment or fill Diving Cylinder s.

SOURCES OF DIVER TRAINING

Many " or qualification card.

A good dive training organization, such as a dive school based at a dive shop, will always offer courses to the standard of a recognized certification organization, such as those listed below. Many dive shops in popular holiday locations offer courses that can teach you to dive in a few days, and can be combined with your vacation. Upon completing the course the student is issued a certification card.

Many diver training organizations exist:

Entry-level recreational SCUBA diver training organizations:

--- using professional instructors. Examples of this type are ACUC , SDI (Scuba Diving International) SSI , PADI and NAUI

--- amateur instructors. An example of this type is the British Sub Aqua Club

Technical recreational SCUBA diving organisations. Examples of this type are ANDI , DSAT Tec (PADI), GUE , IANTD , TDI , USC (SSI), and NAUI Tec

Commercial diver training organizations. Train divers for Professional Diving using SCUBA, Surface Supplied Diving and Saturation Diving equipment and techniques.

National navies and armed forces. Train divers for ship maintenance, salvage and repair, rescue, mine clearance and covert operations using SCUBA and more advanced equipment and techniques.

LOCATION OF TRAINING LESSONS

Initial training typically takes place in three environments:

Classroom - where material is presented and reviewed

Swimming pool - where skills are taught and practiced in confined water

Open Water - where the student demonstrates the skills he or she has learned.

Typically, early open water training takes place in a local Body Of Water such as a lake, a flooded quarry or a sheltered and shallow part of the sea. Advanced training mostly takes place at depths and locations similar to the diver's normal diving locations.

The usual sequence for learning most diving skills is to be taught the theory in the classroom, be shown the skill and practice in the pool using the minimum equipment, then practice again in open water under supervision in full equipment and only then use the skill on real dives.
