Sit tight on channel edges and fish close and SLOWLY on the flat above and the drop
Sit off the ledge and pitch up onto the flat , slow roll it to the edge close to the bottom and let the jig drop on the drop off
Needs to have baitfish in the mix , bait should be easy to find
The crappie will cruise the edge
Set your graph to chirp and listen, multiple chirps is key ...
Or LS them if you got it
10 foot deep flats and quick drop offs 15 to 20 foot deep
Luck to ya
