How to Tune a Crankbait for Perfect Performance

A properly tuned crankbait should run in a straight line directly behind the boat or rod tip. If the bait consistently pulls to the left or right, dives erratically, or twists your line, it’s likely out of tune. These issues can be caused by:

• Bent eyelets due to snags or rough handling
• High-speed trolling or casting in turbulent water
• Manufacturing defects or wear over time

Learning how to tune a crankbait is straightforward and requires only a few tools:

Tools You’ll Need

• Needle nose pliers
• Crankbait tuning tool like the Off Shore Tackle EZ Crankbait Tuner

Step-by-Step Tuning Process

1. Cast your crankbait into the water and retrieve it slowly to observe its path.
2. If the bait pulls to the left, gently bend the eyelet (line tie) to the right using pliers. If it pulls to the right, bend it to the left.
3. Make small, incremental adjustments—over-bending can ruin the bait’s performance.
4. Test the bait again. Repeat until the crankbait runs straight without veering to either side.

Important tip: Always adjust in the opposite direction of the pull. Small changes go a long way.

Many anglers only think to tune a crankbait when they notice it swimming poorly, but regular checks are a best practice. Tune your crankbait:

• Before every trip to ensure consistent action
• After every snag or heavy strike
• Whenever you change lures or switch rods 

Knowing how to tune a crankbait can be the difference between a frustrating day and a successful one on the water. A properly tuned crankbait tracks straight, maintains the right depth, and presents a lifelike action that fish can’t resist. Whether you're casting or trolling, taking a minute to check your lure's tune is time well spent.

Add a tuning tool to your tackle box and make it part of your routine. Your crankbaits—and your catch rate—will thank you.
