	I missed the lead article here, so forgive me if this goes
astray (PS: No, I'm not really a Prince fan...)...

	If you are looking for a water *proof* (as opposed to, say,
water *resistant*) ultrasonic transducer, you might want to consider
going to a marine supply house or wholesaler, and checking on the
price of a depth sounder head.  Of course, as we all know, the 3 most
expensive words in the English language are "marine" and "mil-spec",
but, if you are, for example, building your own depth sounder, you
might want to spend the money.  It seems to be a better alternative,
in the long run, to having your boat sink...
