A movable center-of-gravity tube comprising a tube body (41), a center-of-gravity body (42) accommodated inside the tube body and balls (43) held on the center-of-gravity body (42) is provided, in which the center-of-gravity body (42) has a slightly smaller diameter than the diameter of an inner surface of the tube body and comprises three or more rows of ball circulation grooves (44) on its outer surface in parallel with each other, in which the ball circulation grooves (44) accommodate the balls in a circulation manner, and each of which comprises two rows connected to each other, in such manner that the balls in one groove of the ball circulation grooves rotate and circulate in contact with the inner circumferential surface of the tube body, while the balls in another groove rotate and circulate in no contact with the inner circumferential surface of the tube body, when the center-of-gravity body moves.

A lure includes a body, a weight, a guide member and an elastic member. The body is hollow and has a head in a front portion and a tail in a rear portion thereof. The weight is inside of the body so as to be movable in a front-rear direction. The guide member is in the body and configured to guide movement of the weight in the front-rear direction. The elastic member is in the body and is configured to generate an energizing force to move the weight in a forward direction. The weight is movable backward against the energizing force of the elastic member and one of the weight and the elastic member is inserted into an inside of the other.

Hydrofoil fishing lure apparatus for use with trolling techniques behind a boat. In one embodiment, the hydrofoil fishing lure apparatus includes an artificial lure having a body. A hydrofoil that includes a strut and a lifting surface, with the strut for the hydrofoil being attached to the body of the artificial lure is also included. In some variants, the artificial lure may be modeled after flying fish species. Wing retraction elements may be utilized on the hydrofoil to retract or expand the wings of the flying fish to provide for a more natural presentation. Other variants described herein include fishing lure platforms that include a hydrofoil that allow for the mounting of frozen, live, or other types of artificial baits on the hydrofoil itself.

A directional guide for a spreader bar includes a body extending along a longitudinal axis. The body includes a first fin and a second fin spaced apart from the first fin. The first and second fins are coupled to the body and are configured to control a vertical position of the body in water through which the body is moving. Grooves are formed in the body. The grooves include a first groove extending along the longitudinal axis of the body, a second groove crossing the first groove and a third groove crossing the first groove. A keel is rotatably coupled to the body. The keel is configured to rotate between the first groove, the second groove, and the third groove. The keel is configured to control a lateral position of the body in water through which the body is moving.

The present invention relates to an improved fishing lure having the ability to be camouflaged. More particularly, the present invention relates to a fishing lure having multiple catching devices with capacity for varying the bait and size of lures, having a built-in compartment adapted for the insertion of live bait or chum used in the attraction of fish.

A fishing lure comprises a body having a front end and a rear end. A cavity is positioned towards the front end of the body, and the cavity has a longitudinal direction. A connection member is located at least partially in the cavity and retained thereto by one or more retaining members. Each retaining member is able to extend into the cavity to retain the connection member in the cavity in use. The connection member is able to move, in use, in a direction transverse to the longitudinal direction.

A lure includes a first and second body parts, a structure in which the first and second body parts are coupled together, and an interior cavity, and a rod bridging the first and second body parts in the interior cavity. The rod has a rod portion, a flange portion connected to a first end of the rod portion, and a projecting portion projecting from the flange portion to an opposite side of the rod portion. The first body part has an inner surface and a rod hole on the inner surface thereof. The second body part has an inner surface and a base projecting from the inner surface thereof, and a receiving hole recessed from the surface of the base. A second end of the rod portion is inserted into the rod hole, the projecting portion inserted into the receiving hole, and the flange portion in contact with the base.

An autonomous, artificial bait aims to simulate the movements of natural baits. The autonomous bait may be designed to appear as a natural bait such as a crawfish, shrimp, worm, or minnow. The autonomous bait includes a cavity in which a gas producing engine may be received. The gas producing engine includes a gas producing agent that produces gas when it interacts with water. That way, when water enters the gas producing engine, gas may be produced that interacts with the autonomous bait to cause movement of the bait that simulates the movements of a natural bait it aims to imitate.
