Three-dimensional maps in full color of each site illustrating 27 of the most spectacular dives along Australia's Great Barrier Reef. These maps offer what no book has ever before provided: the information needed to plan your dive down to the last detail. You can review the exact layout of the site -- including depths, sizes, and distances between reefs and wrecks or any hazards -- and even the lighting conditions for optimum underwater photography. The short chapters covering each dive provide crucial data about depths, currents, weather variables, and plant and animal life, and each book ends with a full-color visual encyclopedia of the most common fish that inhabit the area. The experts' lively text has been vetted by Diving Science and Technology Corp. (DSAT), which is a corporate affiliate of Professional Association of Diving Instructors (PADI), making these the most reliable guides for the expert as well as the first-time diver.
