Is the OP still there?
Why not contact him directly and ask? If you go to Poyer.com there is a means by an online form or snail mail.
I?ve recently read a couple of books by David Poyer. He writes pretty convincingly about cave diving yet uses some terminology more commonly used by open water divers. Anyone know Poyer or about him?...
