I haven't done a lot of pompona fishing. Have caught a few off Navarre Beach though a few years back when we still lived in Navarre.Never had any luck with jigs, butagain,I didn't do much. I used sand flees. Just hook them and throw themout. If I remember correctly, there is a second sand bar and it seemed we had to get them past it. A sand flee scoop (or whatever its called) is not that expensive and you can dig up flees pretty quickly.
You can have two hooks on your line so do that. Do you know how to fix the rig?
Look for a wash out in the sand bar and fish there. The wash out will be a where the waves aren't breaking but they are breaking on either side. Basically, look for a stretch in the "breaking" line where waves aren't breaking. Does that make sense???
