Abstract
An artificial fishing lure having pressure sensing and hydrostatically controlled depth selection and guidance means adapted to cause said lure to seek and hold a predetermined depth in a body of water where fish of a selected species may be expected to be found. The lure is made of buoyant material and comprises a central cavity housing a hydrostatic pressure-sensitive rotary piston. A pair of elevator fins are mounted on the sides of the lure body and move up and down upon rotary motion of the piston in response to changes in water pressure.
