"The Complete Diving Manual" covers every aspect of diving and is an indispensable handbook for anyone learning to dive. It covers all the theory, from the gas laws, how light and sound travels underwater to how diving affects the diver's body. Every aspect of the equipment is described, from how to use it to how to maintain it. However, the book offers more than just a handbook on the theory of diving. Jack Jackson, who has been diving for decades and seen the sport grow, writes with authority and from personal experience, with valuable hints and clear explanations. Divers are shown how to respect the environment and enjoy their sport with minimum impact on the underwater world in which they are privileged to immerse themselves. Other important aspects include identifying dangerous underwater organisms and how to deal with medical emergencies.
