Look for mullet jumping in really close. A big school of mullet stirs up the bottom and that sends the redfish into a near-frenzy.
You have to ride right along the grassline (not reccomended around Econfina, unless you're traveling pretty slow and have protection for your foot), or else you might pass right by and never see them. If you accidentally run right over them, move away for a few minutes and they will regroup, then either push pole, use your trolling motor or just set up a drift right over them. They can be spooky in shallow water, so being quiet is very important.
Once you get right in the middle of the school of mullet, look for wakes that are too big to be a mullet and cast in front of it. Or just throw some blind casts. If they're there, you'll know in just a minute, if they're not there, move on to the next cove or creekmouth. Out of Econfina, you should be able to find a school or two pretty quick.
Good Luck!
While I said the spots I fish are known by many others, I will say this too -- multiple board members didn't just give them to me. Instead my buddy Sharkman and I used kayaks and canoes to learn the Ecky / Hickory Mound area like the back of our hand (often on low tides) so that we found the public bars AS WELL AS some harder to find spots, and over time figured out which ones gave us the highest percentage odds on holding keeper reds. We both have boats now, but the recon efforts done years ago with paddle work continue to prove invaluable.
