The book works, and works well because of several reasons.

First, it provides (still valid) contact information on dive operators and lodging providers in the different areas, as well as providing general ideas on price range for these operations.

Second, the book gives a good briefing and summary of the different dive locales in the Philippines, providing pros and cons, as well as tips that are useful to the would-be traveller.

Third, the book provides a near-comprehensive listing of specific dive sites in the different locales. While the underwater environment changes, it does so slowly, and practically all assessments and descriptions still hold. It provides info on what to expect in terms of depths, surface conditions, currents, as well as what to see. It also provides a quick rating in the form of stars, as to how good the sites are. These are highly accurate, although some have been under-rated, in my opinion.

Fourth, the photography is great. The book has been designed well, and is quite engaging. Full-color photographs are peppered throughout the book.

The text is getting old, but that doesn't change the fact that it holds its promise well of talking about the dive sites in the Philippines.

I can understand why no one has come up with anything to replace this book.
