Now here’s something every diver should have – the Diving Almanac & Yearbook by Jeffrey J. Gallant, published by Porbeagle Press.
I have the 2007 edition and it’s brill! Chock-full of useful information about diving, and refreshingly for an American publication, covers an impressive proportion of the entire planet. Europe, for instance!
Excellent value at £11 for 550 pages. I’ll post an extensive review soon.
