I gave the set 5 stars basically because the set itself deserves it. It is exceedingly well laid out, referencing the creatures and fish by shape and size etc, which after all, if you don't know what the fish is, is all you've got to go on. Photographs are excellent, and they are photos not drawings!, and the descriptions include habitat and reaction to divers. HOWEVER - the whole set refers only to Florida, Caribbean and Bahamas, a point that is not made. If you live and dive anywhere between the Maldives and Australia, the set is not what you're looking for. It is missing some of the most well-known, abundant fish in the Thailand, Malaysia, Bali belt, so trying to find a fish that you DON'T know is going to be impossible. But if you're diving off the East coast of USA - brilliant!
