Abstract
An artificial fishing lure having temperature sensing and thermostatically controlled depth selection and guidance means adapted to cause said lure to seek and hold a pre-determined thermal stratum in a body of water where fish of a selected species may be expected to be found. The lure is fabricated of buoyant material and comprises a central cavity housing a bimetallic heat-sensitive spiral-shaped thermostatic element therein. A pair of elevator fins are positioned on the sides of the lure body and will move up and down upon motion of the thermostatic element in response to water temperature changes.
