Abstract
A fishing lure has a lure body and a chamber open to an interior of the lure body. An intake extends from the outside of the lure body to the chamber at a first end of the chamber. A discharge extends from the outside of the lure body to the chamber at a second end of the chamber. A plunger sealingly engages a circumference of the chamber and is connected to a stem. The stem is adjustable between a first, a second and a third position located on a tongue extending from the lure and results in the plunger being displaced within the chamber. The plunger acts to draw ballast within the intake and to discharge air through the discharge opening to adjust the operating depth of the lure.
