The British Sub Aqua Club is famous throughout the world for its unprallelled quality of scuba diving instruction and this book is one of the most important components of this structure. For those who have never dived before it gives an enticing look at what there is to see and do underwater and shows that contrary to popular misconceptions scuba diving is a safe sport. For the diver who has just started to learn it details the techniques required to dive safely and for the experienced diver it proves an excellent resource into the knowledge and skills required to dive safely in a wide range of circumstances. The BSAC has a number of books on scuba diving including: Advanced Sport Diving, Boat Handling, Search and Rescue.... As a diver I find this an invaluable resource to make sure that I know what I need to and occasionally give me inspiration to look into new areas which I might not have originally thought of.
