Not every dive has to be deep (but the best ones often are): Some of the best recreational diving takes place in water deeper than 20 m/65 ft. Such dives include wrecks and walls. The Deep Diver course builds on the skills you acquire as part of the Advanced Diver course to help enable you to make these dives safely and more effectively. Among the topics you will learn:
- The purpose, problems, hazards, planning, preparation, equipment (additions and modifications), air supplies, personnel, techniques, gas management, emergency procedures (including location and transportation to a hyperbaric chamber) and depth limits for recreational diving.
- Decompression-related topics include nitrogen narcosis and decompression sickness (definition, cause, symptoms, signs, first aid and prevention) history of decompression, concepts, use of dive computers, definition of terms, problems, principles and techniques.
- Complete coverage of advanced gas management, problem solutions, exceptions and dive planning are also included.
- Altitude diving, flying after diving and hyperbaric chamber access and operation is included, as well as other short- and long-term deep diving hazards.
