Safe cave diving is no accident. Over time, many divers both trained and untrained in the art of safe cave diving have died in caverns and caves. Despite the fact divers are better educated today about the hazards of the cave environment, deaths continue. Trends show the cave diving community is effectively educating divers who lack cave training. Numbers of deaths among those who lack training continue to remain low. The numbers of deaths trending upward are among those who have been certified to cave dive. It is because of this concern the NACD is producing the book, Guidelines for Success. Times change and so do divers, techniques, and technology. With this in mind, we hope to offer the newest information available with a style that is positive and encourages divers to focus on making smart choices. Due to the fact that fatalities of certified cavern and cave divers is increasing, this book will include information directed specifically at those divers as well as those preparing to train. It will also provide good resource material for both sport and technical divers.
