Curriculum
Programme Structure
The programme is structured in 5 modules, listed below in order of study.
01
Fundamentals of autonomous diving, safety principles and initial knowledge of the underwater environment
- Concept of tank diving and differences between autonomous diving, apnea and other underwater modalities Recreational and technical
- Basic physical principles applied to diving: pressure, volume, buoyancy and elementary effects of the underwater environment on the body
- Basic safety rules in basic diving: never dive alone, control of the partner, initial limits and responsible underwater behaviour
- Basic manual signals for underwater communication for coordination, control of immersion and response to simple situations
- General knowledge of the aquatic environment: visibility, temperature, currents, depth and factors that condition a safe dive
02
Autonomous diving equipment, function of its components and basic procedures for preparation and verification
- Main components of tank diving equipment: mask, tube, fins, vest, regulator, bottle, ballast and basic instruments
- Tank and compressed air system function: respiratory supply, working pressure and elementary consumption control
- Main regulator, alternative source and manometer: correct use, previous checks and basic safety criteria
- Compensator vest and ballast system: buoyancy control, surface adjustment and function during descent, permanence and ascent
- Installation, adjustment and basic review of the equipment before dive: Sequence, cross check and simple error detection
03
Basic techniques on the surface and underwater for the initial handling of the equipment and the adaptation to the underwater environment
- Inlet and outlet of water under controlled conditions: basic techniques from shore, platform or boat with self-contained equipment
- Regulator breathing, adaptation to the use of compressed air and initial control of sensations under water
- Mask emptying, regulator recovery and resolution of simple incidents as basic skills of the beginner diver
- Initial control of buoyancy and body position in immersion for stability, comfort and elementary safety
- Basic techniques of flapping, displacement and control of underwater movement with minimum effort and better efficiency
04
Basic dive planning, air control and procedures for descent, permanence and safe ascent
- Basic preparation of an initial recreational dive: objectives, moderate depth, estimated time and review of environmental conditions
- Controlled descent procedures: ear compensation, adequate rhythm, visual control and coordination with the partner
- Control of air consumption and basic reading of instruments to maintain margins of safety during the dive
- Permanence in the bottom with depth control, buoyancy, simple orientation and attention to the immediate environment
- Safe and paused ascent: Controlled speed, companion surveillance and correct immersion completion
05
Capstone Project for the preparation, execution and evaluation of a basic dive with autonomous equipment in a controlled or simulated environment
- Definition of the immersion scenario: type of environment, water conditions, practice objective and profile of the beginner diver
- Complete preparation of the diving equipment: assembly, adjustment, functional verification and check with partner before entering the water
- Design of the basic immersion plan: depth, time, simple travel, planned signals and control of air consumption
- Simulated execution or practice of essential skills: breathing, buoyancy, displacement, communication and resolution of simple incidents
- Evaluation of immersion development: technical control, safety, co-ordination with partner and compliance with basic procedures
