Central Florida is like diving in soup for certain. Visibility is limited at best. When we do have to dive up there, we call it "bump and dive." LOL
There is a publication available at most Dive Shops here in South Florida and for $16.00, it's well worth it. It's called the "Boat Dive Book." It's hard to mistake as it's very plain and adorned with a Dive Flag on the front of it. It has the numbers for your GPS in it, environmental descriptions, visual references of the sites and wrecks and what to expect to see on the sites. Not fancy, but informative. It also has a sister book called "Beach and Shore Diving" which has a number of choice sites in it.
I've been diving and teaching (NAUI) in Florida now for over 30 years and another site that gives some spots off the beaten path is NOAA's site. And, they have all the Long and Lats to boot.
Have a great time down here in Florida. It's truly a unique blend of Mother Ocean.
Keep it safe,
