The Gulf Stream rushes across South Florida like a river beneath the surface of the Atlantic Ocean. It acts as nature's very own pressure cleaner, pushing away the dirt and debris from the reefs and wildlife in the waters off Broward and Palm Beach counties. That makes South Florida, despite its overdevelopment, one of the world's most fabulous dive spots. Divers from all over travel here to see the life-cradling coral reefs that rest just below the water's surface. You can see it all for yourself with the help of the folks at Lauderdale Diver. This spacious dive shop, only minutes from Fort Lauderdale Beach, offers everything a beginning or experienced diver could need -- from bathing suits and Freestyle underwater watches to Aqua Lung regulators and Body Glove wet suits. What's more, Lauderdale Diver's PADI certification courses cater to the needs of busy Floridians. In addition to a traditional two-week diving certification class ($275), Lauderdale Diver offers a flexible nights-and-weekends class ($325) and a name-any-time-you-want private class ($395). Ask for Judith or Shelly, who can tell you about the magnificent underwater world you've been missing.
