I certainly understand your situation. There have been plenty of views of this thread, but no replies. I moved to Florida a few months ago from Oklahoma and have found locating crappie (specks) very difficult and useful information difficult to find. I bought a cheap little fishing boat and have been exploring the area lakes and rivers - Harris chain, Ocklawaha River, St John's River. I usually manage to find 1 or 2, but really have to work for those and never really get into a lot of them like I'm used to in Oklahoma (and Kansas). I assume that finding them here is much different than other places where there is structure in the rivers and lakes - like brush piles, rock ledges, depth variations (more than a foot or two).
I've stopped and talked to every crappie fisherman I see, trying to learn the patterns and techniques. I've heard that people are catching lots of them in a lot of different places - both in the open water, and the lilly pads. I've also heard that the primary spawning month is February.
I have fished Eustis from the fishing pier and managed to catch 1 or 2. I haven't explored it from my boat yet. I don't have all the fancy electronics or a fancy boat, and I clearly don't know anything about catching Florida crappie, but if you want to get out on the water, I'll do what I can to help.
Best of luck!
