If you are like me, I would catch my most of my crappie in the spring and fall. When the dead of summer hit…they disappeared. Now I know they suspend into deeper water near vertical breaks to deep water. Bait fish move from the shallow areas to these same cooler areas and so do the crappie.
Find the sloping break to deep water and you will find the crappie lined up in columns of temperate water on your fish finder. The only thing you need to do is run a crankbait through the line under a slow troll. When your pole doubles up you have a hook up. Changing up colors to each pass and varying depth by alternating your troll speed slightly will stimulate reflexive strikes with each pass of the boat. Often times bites occurring during the turn of the boat so look to turning rather than a straight line troll and keep mixing it all up.
Best crappie lures: Rebel crank-R crankbaits, Luhr Jensen hot shot, Strike-king slab hammer, Bandit Lures crankbaits 300 series
The best size of crappie crankbaits would be under 3 inches.
