On this matter, it is only to be stressed that the training stage in the swimming pool must be considered - for its delicacy - only from its preparatory aspect, when compared with the one performed in natural environments, in which the aspirant diving technician will attend to his professional activity, in other words in lakes, rivers, seas and so on.

In fact, the importance as well as the limitation of a training course to be performed into the warmish waters of a restricted pool, in minimal depths, heated ambient and without atmospheric agents, confronted with what is needed to face the different situations characterizing traditional surroundings in which the T.D.O.'s (Technical Diver Operators) will operate during the execution of their profession, even in very different geographical areas (from the North Sea to Africa, from Africa to the Middle East, Borneo, Tanzania, Persian Gulf a.s.o.), is very clear.

So, the swimming-pool training must not only strengthen physical skills already detected during the sanitary aptitude test and psycho-physical valuation, but moreover enhance those performing skills principally dealing with SELF-CONTROL, with particular care for:
 

	the acquisition of a "watery-disposition" allowing the operator/student to face the first and only, irreplaceable training/operative environment the School has found since 1959 in the waters of a lake (Bracciano, in this case).
	knowledge and utilization of diving gear and outfits of individual employ;
	the gradual strengthening of the upper and lower limbs and of the breathing system;
	the psychological concentration for the development of basic technical behavioral methodologies in water, with particular care for the achievement of a psycho-physical balance related to COORDINATION, SELF-CONTROL, OPERATIVE DISCIPLINE, DIVING HYGIENE, the execution of preparatory underwater activities, constantly carried out respecting the protocols, which must necessarily promote hygiene and operational safety;
	development of mnemonic faculties which, in entrepreneurs' circles, identify themselves in a profitable and appreciated PROFESSIONAL PERFORMANCE;
	the operating skill even in total absence of visibility;
	the application of operative skills connected not only with accident-prevention, but also with TEAM WORK and OPERATIVE SKILL.

	SELF-CONTROL;
	COORDINATION;
	DIVING HYGIENE;
	OPERATIVE DISCIPLINE;
	MNEMONIC DEVELOPMENT;
	SPATIAL DISCRIMINATION;
	ENVIRONMENTAL ADAPTATION;
	PSYCHO-SUITABILITY.

This training phase, experimented during 40 years of activity and continuously developed, is essential for the student's psychological, physical and technical training, not only in terms of the crucial knowledge of accident-prevention regulations, but even and mostly for the repression of those psychological obstacles conditioning the conscious and rational "penetration" of the liquid environment by anyone performing such activity in an ambient calling for conscious tranquillity of execution, which should be as close as possible to terrestrial situations.

The swimming-pool practices have all been continuously studied, experimented and updated by the School, in order to develop self-control and a controlled and rational practice of all the procedural rules, according to safety.

So, the School's qualified students, trained by such a teaching typology, taking care of the psychic, physical end technical skill's development, through all the training stages given within the practical training in swimming-pool, lake, sea, turret, hyperbaric chambers and so on, will result in the highly balanced technical/training product in psychological, physical and technical terms, thanks to the ability to put into practice accident-prevention methodologies, which have always been the best if not only form of physical preservation.
