A chumming device for live bait has a shaft with a first end located opposite a second end. A head is connected to the first end of the shaft. The head has a plurality of openings that facilitate water flow while scooping bait from a live well. The head has a lower portion forming a chamber configured to retain the bait. The chamber has a first side wall located opposite a second side wall. The chamber has a lip located opposite a protruding structure. The protruding structure extends beyond the chamber opening and is configured to align the bait to be launched in a direction by the force of a user. A handle is connected to the second end of the shaft. The shaft can have a plurality of bores each have different sized diameters arranged in an ascending diameter. The shaft can have a plurality of shaft openings.

Many different types of systems are utilized and tasks are performed in a marine environment. The present invention provides various configurations of castable devices that can be operated and/or controlled for such systems or tasks. One or more castable devices can be integrated with a transducer assembly, such as a phased array, that emits sonar beams and receives sonar returns from the underwater environment. Processing circuitry may receive the sonar returns, process the sonar returns, generate an image, and transmit the image to a display.

A fish calling device for attracting predatory fishes by mimicking all sensory characteristics of a prey including appearance, sound and smell is disclosed. The device is configured to spray water into a waterbody around the device in a circular or a semi-circular pattern, thereby mimicking the appearance of a group of bait fishes. The water is sprayed to create the sound of a bait fish trying to escape from the predatory fishes when sprayed onto the waterbody. A scent bag is attached to the sprayer for dispersing/dispensing a smell through the water sprayer thereby mimicking the smell of a bait fish. Thus the device activates three senses of the predatory fishes including sight, hearing and smell for attracting them while fishing/competition.

A device for attracting aquatic and marine life is disclosed. The device may generate an output in a body of water that simulates the feeding or distress of other aquatic or marine life forms. An example device includes a head coupled to a supply line to provide gas and/or liquid to the head, and an agitator coupled to the head. A plurality of arms of the agitator have a plurality of openings therein to output the gas and/or liquid into a body of water and cause a disturbance. In an example, the agitator sits above, at, or below the surface of a body of water and discharges the gas (or fluid), and/or moves under the influence thereof, to create a disturbance in the body of water, such that desired species of aquatic and marine life are attracted to the disturbance.

A chum delivery device having a body with a plurality of openings, at least one open end, at least one removable cap, and one or more hook attachments. The plurality of openings of the body are configured to allow chum housed within the body to be released. The removable cap(s) is/are configured to seal the open end(s) of the body.

The present disclosure discloses a method of using an unmanned aerial vehicle (UAV) comprising a housing, a processor, a positioning unit, a sonar unit, a launching unit and a fishhook unit in fishing. The method comprises manipulating the UAV to fly to a designated destination determined by the processor according to one of a received wireless communication and a preset program, adjusting the sonar unit to a predetermined height by the positioning unit, determining a coordinate corresponding to a signal detected by the sonar unit as a fishing region when the signal is consistent with a predetermined value, launching bait to the fishing region by the launching unit, releasing a fishhook from the fishhook unit to the fishing region, and manipulating the UAV to hover or return by the processor according to one of a received wireless communication and a preset program.

The present disclosure discloses an unmanned aerial vehicle (UAV), comprising a housing having a top part and a bottom part, a plurality of arms arranged on the top part, a battery unit arranged within the housing, a processor arranged within the housing, a launching unit having a slide bar and a driving component, and a supporting component arranged on the housing to support the slide bar. One end the slide bar is rotatably connected to a pivot. The other end of the slide bar is slidably connected to the supporting component. The driving component is to actuate one of the slide bar and the supporting component to separate the slide bar from the supporting component. The slide bar is to rotate about the pivot after separating from the supporting component. An UAV readily configured for fishing can be provided by embodiments of the present disclosure.

The present disclosure discloses an unmanned aerial vehicle (UAV), comprising a housing having a top part and a bottom part, a plurality of arms arranged on the top part, each arm having a motor and an airscrew, a battery unit arranged within the housing, a processor arranged within the housing, a sonar unit having a wire connected thereto, and a positioning unit detachably mounted within a mounting groove recessed from the bottom part, wherein the positioning unit is connected to the wire and configured to retract or release the wire. An UAV readily configured for fishing can be provided by embodiments of the present disclosure.
