Title: Useless GPS Coordinates
Review: Though I am a cavern diver, I have not tried to use this book for this purpose. I have tried to use it for finding dive sites in SE Florida. In this regard, the book is nearly useless. Many (if not most) of the GPS coordinates provided are just plain wrong. Obviously the author is relying on outdated (at best) or totally unreliable third party information. I frankly doubt that the author has ever been to most of the SE Florida open water dive sites written up in this book. This book is a waste of money for open water divers.
