Trolling
I'm not the best fisherman,but this is what I do.
I will troll as slow as possible,using 4 poles with 2-3 jigs on each ,with different colors,so I can possibly find the color the fish want that day. I watch my sonar & the surface of the water for bait fish. I try to circle over the schools of fish with jigs set just under them. I may have one pole set to run just off the bottom,just in case, of some that may be deeper.
If I find crappie I may fish a few more poles. I'm sure I left something out,I hope this helps.
The fish were bitting yesterday, The fish will bite tomorrow,,, today I must buy my fish
