An improved means for adjusting the angle of attack, the angle of the plane of the diving lip to the longitudinal axis of a lure, of a diving lip on a fishing lure, having a body with a longitudinal axis, comprised of a retention spring, a pivot pin, and a series of grooves in the face of the lure into which the diving lip seats, so that the angle of attack of the diving lip can be readily changed by pulling the diving lip out of a groove, by compressing the retention spring, moving to another groove and releasing it.
