Title: Not Worth It!
Review: This low quality spiral bound notepad of cheap drawings contains some of the most ridiculous and non-intuitive signs I've ever seen. Some of them are just plain wrong, in my opinion. The 5% of the book that is of any value is, in my experience, common knowledge from basic open water training. I expected a book of signs that makes use of common expressions that transcend spoken language, at least in the western hemisphere, and can be easily understood by a buddy team that does not have much experience diving together. The book should be called The Smiths Sign Language Manual and not Scuba Divers Sign Language Manual because I think the authors are the only ones who understand it. In summary, I feel it's a poor attempt to facilitate communication underwater and is not worth the price!
