pressurized. It worked at about 20 feet (roughly 1.66ATM or
25psi total); not sure if it would have worked at greater
Nowadays we use underwater writing slates. ;-)
Or, for that matter, full face/free flow masks with
diver address systems (looking to buy one myself).
Very similar to what the astronauts use:
