Excellent reference book

It's not a bad book and for the price I still believes its worth to have one if you like diving but it's not a requirement either. I was expecting more details information for the equipment chapter and more diving relevant information in general. The first chapter is more for people who doesn't dive yet but are thinking about it. I found The Chapter on the physiology of diving really interesting.

This is a great and absolutely necessary all around reference for every diver, either experienced or just beginning. Much more detailed than any other PADI course book. Easy to read.

It is a very good book. Not a deep encyclopedia for sure, there are likely plenty of better books.
But it is an excellent (and better) complement of OW and AOW books.

It's not an encyclopedia and certainly not a technical reference. It's a very general, lightweight (as in depth of information). Nowhere near what is needed for Equipment Specialist. This book however is listed as being "required" by PADI for that specialty but don't bother. It's not that helpful.
