A crank bait lure is provided which can be adjusted to travel to a number of different depths, to cover a range including shallow, intermediate and comparatively deep levels of operation. The lure comprises an elongated body provided with a groove extending into its interior, and further comprises a lip member having a first portion which is receivable into the groove, and a second portion which extends out of the lure body, beyond the forward end thereof. The lip member is slidable along the groove to selectively vary the length of the extending portion, such length being related to the depth of operation of the crank bait lure. The lure further comprises a detent mechanism for releasably locking the lip member at one of a plurality of discrete positions, in order to adjust the extending portion thereof to the length required for the lure to operate at a particular depth. The detent mechanism includes a spring and a locking element operated thereby, both of such components being protectively housed within the body of the lure.
