A crankbait's job is to dive to a specific depth and stay there on retrieve. That's it. Get the depth wrong and you're fishing empty water; the prettiest finish in the world won't fix a 12-foot crank pulled across a 3-foot flat.
Match depth to structure. Three depth bands cover most lakes:
- Squarebill (2-6 ft). Short, blunt-lipped, deflects off cover. Throw at laydowns, rip-rap, and submerged stumps where you're fishing in the shallows.
- Medium-diver (6-12 ft). Rounded lip, longer. The all-purpose bass crank — works on points, shallow humps, and weed lines.
- Deep-diver (12-25+ ft). Big spade-shaped lip, long body. Use on offshore humps, channel ledges, and summer fish stacked deep.
Then pick color in this order: water clarity beats anything else.
- Clear water: natural baitfish (shad, perch, bluegill patterns).
- Stained: chartreuse, firetiger, or any pattern with a bright belly.
- Muddy: solid colors — black, red, orange. Vibration matters more than color here.
Size last. Match the baitfish in the system. 2-2.5" for tight-lipped fall fish, 3-3.5" for general use, 4-5"+ when you're hunting big fish on big water.
