A scuba-diving handbook. It features text and step-by-step photographs and illustrations, leading the novice scuba diver from the earliest stages of underwater training through to diving in open water. Adopting a general approach - mindful of the differences between the various certifying agencies, but not tied to any particular course outline - the author focuses on the training requirements for a basic open-water certificate. The scientific laws and physiology of diving are covered, as are essential survival and safety techniques. Other chapters cover the use and maintenance of equipment, mobility and buoyancy underwater, dive planning and diving in different types of water.
