I'm a Divemaster and have been fortunate enough to spend time in the South Pacific, as well as many other other scuba-locations offering extraordinarily clear water. Looking for meteorites underwater would be, if anything, much more problematic than looking for them on land, because: a) a freshly-fallen meteorite and a rock would appear just as similar underwater as topside, and b) then, as you descend below 30 feet or so, colors quickly dissipate, making most all objects blend in together even more, and c) any highly metallic object would disintegrate rapidly in a marine environment, and d) any meteorite which didn't disintegrate would soon morph into just another coral-encrusted mini-reef, like virtually any other underwater rock surface, and e) searching with a metal detector, like any kind of underwater motion, would be much more slow-going than on land, and f) at least on land, you don't have to interrupt your search every 55 minutes to switch tanks, and g) decompression-sickness considerations strictly limit the time one can spend at any given depth. I suspect there are reasons h, i, j, and k too, if we think about it.... I often looked at rock formations underwater, and wish-and-wonder.....but realistically, I'd guess the chances are even more remote than stumbling onto something in one's backyard.
