Yeah, the chairman put up a fine post. He forgot to include some fine east coast dives.
Jupiter the northern bound of the east coast diving in south Florida. It is known for the Jupiter high ledge which is a reef at 80'. The ledge gets current from the Gulf Stream. Large creatures are common there: sharks, turtles, and Goliath grouper. The is a popular dive to "the hole in the wall". It is a swim through at 145' and is a tech dive. Recreational divers can do this after a training session. Jupiter is drift diving.
West Palm is just south of Jupiter. It is drift diving and about 60'.
South of that is Pompano which has a variety of wreck and reef diving. You can see nice populations of soft corals at Pompano.
Fort Lauderdale has diving but I have never done it. I live in Orlando. It is just as easy to go down to Key Largo. Key Largo has nice hard corals, soft corals and good fish populations.
