I'm a certified Scuba diver as well. I've done a handful of dives here in FL
(don't have the time for alot these days)
Some of my favorite:
-Devil's Den near Gainesville...big sinkhole in the middle of a field, about 50' of cave-ish diving
-Crystal River..one of the best, clear water, beautiful fish, and alot of manatees...really clean freshwater
-St Augustine...the Navy dumped alot of A-6's off the coast, you can dive out there and swim around the old airframes, which are now artificial reefs.
Pretty much any wreck dive is going to be awesome. Although it's sad, when they finally do sink the USS Oriskany, it'll be one hell of an interesting dive, near Pensacola. http://www.ussoriskany.com/id18.html
