This tip on how to tune a crank bait applies to a new handmade lure you might make as well to any lure you may purchase.
Most often crank baits come out of the box tuned and ready to run true on retrieve. Sometimes they may need a little tuning and it is also possible for a crank bait to get out of tune while getting beat up bouncing off structure or while in the tackle box.
Tuning a crank bait is a fairly simple process when you know the basic guidelines. To adjust or “tune” a crank bait simply bend the line tie to the left or right, depending on which direction it is running, a fraction of an inch. The line tie is the wire that you tie your line to. It can be on the diving lip of the crank bait or on the nose of the lure.
When performing this procedure hold the front of the crank bait facing you.
If the crank bait is running left; bend the top end line tie to the right. If the crank bait is running to the right; bend the top end of the line tie to the left. A small pair or needle nose pliers is the best tool for this job.
The process may take more than one attempt to get it right in that you should make small moves on bending the line tie.
