Rating: - How deep is deep?
This is one of several books in this series. The mixed gas chapter is a copy from the Mixed Gas Diving book, so if you are collecting the series beware. Otherwise this is a good read. Slightly dated now the book covers the whole topic of deep scuba in depth, if you excuse the pun. In addition to discussing the record breakers and extreme divers there is practical help for the recreational diver too. Essential reading for those divers wishing to venture beyond the so-called "safe" 30 meter limit, it should be on every serious diver's bookshelf.
