A recent review from "Fred" on Amazon, Canada (typos and all):
This book is a quick and pleasant read with important information for all new divers and perhaps some good reminders for the veterans. We have all been taught and continue to work on our diving techniques, but no one else so clearly teaches the social conventions associated with scuba diving. Many, if not most of the book's lessons can be generalized under the heading of "Practice Good Manners". However, the authors deal with some "rules" for situations that Dear Abby would never have covered. The authors provide useful thoughts, often illustrated by humourous anecdotes, on such matters as avoiding underwater crowding, expected behaviour on dive boats, and a host of other situaions. Staying slightly above and behind other divers is a great tip. My only criticism of the book is that it is too short in length. I await the sequel and hope it is loaded with more anecdotes. People can be boorish anywhere. A crowded diveboat and an underwater group dive both provide great opportunities for the most humourous examples of poor behaviour. After reading this book, hopefully divers will have a little more incentive to keep in mind that diving is usually a shared experience. We should all be dive snobs if it means taking that little bit of extra care for each other. For those who refuse, they should be prepared to read about themselves as the dive snobs expose their boorishness in the next volume.
