Scuba diving is one of the most challenging yet enduringly popular adventure sports. Scuba Diving forms part of a brand-new, vibrant sports series aimed at the adventurous younger (or young-at-heart) person and is the ideal introduction to it. Step-by-step photographs and illustrations work hand-in-hand with an approachable yet authoritative text, 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 a 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 in an accessible manner, as are essential survival and safety techniques. Other chapters cover the use and maintenance of equipment, mobility and buoyancy under-water, dive planning and diving in different types of water. This is the perfect resource for the new diver.
