When he heard I had a bifocal dive mask David
McMillan asked me:-
>You... do a lot of underwater reading, James?
Actually, yes. It really is a good ides to monitor
how deep one is, how long one's been that deep, and
how much air is left. This involves reading the
display of the dive computer.
I don't usually take my ebook with me when diving,
James - in New Hampshire in rain so heavy that it's
a real effort to decide whether to take an umbrella
or a snorkel when going out
