I expect he's referring to surface-supplied professional diving: http://en.wikipedia.org/wiki/Professional_diving Since the "SC" in "SCUBA" is "Self Contained" -- meaning hauling your own tanks of air around on your back which, you know, run out eventually -- that would impose inconvenient limits on time down when doing long underwater jobs. Hard hat diving is in that broad class of serious diving (including any number of other scary things, like caves, going really deep, breathing gas mixtures other than plain old air) which I'm perfectly happy to assume I'll never be involved with. -Jeff
