Paul and I went diving in Malta armed with this guide. Before we went we read it and it gave us a good feel for what to expect. Once we had dived there we agreed that the book gave an accurate reflection.
There were a few times when the schematic maps of the dive sites weren't quite accurate, but in general one was able to picture the dive by the drawings in the book.
I would not agree with some of his fish feeding practices as often in the winter months, the fish go hungry as they have become reliant on hand outs from divers.
