Various implementations described herein are directed to a marine device including a waterproof housing including a mounting element. The housing is configured to be at least partially submerged in the underwater environment and the mounting element is configured to attach to at least one of a vessel or a trolling motor. The marine device also includes at least one transducer and an acoustic speaker positioned within the housing. The at least one transducer is positioned and oriented within the housing such that the at least one transducer is configured to transmit one or more sonar beams into a portion of the underwater environment when the housing is at least partially submerged. The acoustic speaker is positioned and oriented within the housing such that the acoustic speaker is configured to emit the fish attraction sound into the underwater environment when the housing is at least partially submerged.

A chumming device for live bait has a shaft with a primary end located opposite a secondary end. A head is connected to the primary 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 primary side wall and the secondary side wall of the chamber have a first pair of opposing openings that are oriented in alignment with each other and are configured to receive a knife blade when the blade is received by the first pair of opposing openings. A cutting board is located between the first pair of opposing openings. The first pair of opposing openings position the knife blade over the cutting board when the knife blade is received by the first pair of opposing openings.

A rig unit for a fishing line includes a float body and a ballast mass removably coupled to the float body. The ballast mass and the float body are configured to remain coupled together during a launch phase and a flight, and to separate from each other upon impact with the water at the end of a flight path. During flight, when the float body and the ballast mass are connected together, the rig unit is orientated with the float body arranged in front, and the ballast mass arranged behind it. After separation upon impact with the water, the ballast mass is configured to rest on the seabed. The main line has a first section descending from the fishing rod to a guide passage of the ballast mass, and a second section ascending from the guide passage to the float body, which is able to remain immersed, at a distance from the water surface, with a terminal line extending upwards, starting from the float body, to an auxiliary float with which the hook is associated.

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.
