Query: Snorkeling

I read every guidebook I can get my hands on before I go on vacation. Of the pile I took along, this was the worst for snorkeling. My main problem with this book is its tone. It was trying to be too authoritative on every topic. Snorkeling experts they are not. There is a much better book out for snorkeling called SNORKELING MAUI by Malewowski. The maps are much clearer, there are far more places to snorkel and it is much better written.
