After much research prior to our trip last month (Apr 2004), I pass
this information on to anyone who chooses to SCUBA dive in the
Marathon area.  Being NAUI certified since '75, my three sons (12, 16,
18) and I dove with Captain Morgan Dive Tours. I was extremely happy
and highly recommend them.  Doug Morgan captained the boat and his
very competent instructor was the one who dove with us. He runs a
clean operation out of the Banana Bay Resort.  His boat is in
excellent condition, and all his equipment appears new and also in
excellent condition.  We had great weather, and found the dives to be
very interesting.  After completing the four open water dives, he made
an extra trip to our motel one evening to hand-deliver the boys PADI
certificates.  I found him to be professional, extremely
accommodating, and reasonably priced.  The experience makes us want to
go back to the Keys and dive again real soon!
