A hand net device that includes a yoke device having a yoke body, a basket attached to the yoke body, the basket including a net that holds an object and a hoop that attaches to the net, and a handle attached to the yoke body. The hand net device can include a load sensor that generates a weight signal that is proportional to a weight of an object in the basket.

A rotor brake mechanism includes a braking member, a moving member, an elastic member, and an adjustment member. The braking member is disposed in a reel body. The moving member is disposed in a rotor to move to a first position corresponding to a line-winding posture and a second position corresponding to a line-releasing posture, in conjunction with a bail arm, and includes an extended portion that extends toward the braking member when the moving member moves to the second position. The elastic member is disposed on the extended portion of the moving member, and comes into contact with an outer peripheral surface of the braking member when the moving member moves to the second position. The adjustment member is disposed between the extended portion of the moving member and the elastic member, and adjusts a position of the elastic member.

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.

An apparatus is described for reducing formation of ice in an ice fishing hole. The apparatus includes low voltage variable speed motor contained within a housing that draws water into and up through the housing and out of the housing through a matrix of multiple rows and columns of holes that form the water outlet.

Apparatuses, methods, and systems are provided for making the harvesting of sea life efficient. For example, real-time or periodic information about the status of the many traps a fisherman may have set is communicated to the fisherman while the traps are still in the water. A fisherman can use this information to determine the best time and path for trap retrieval and reset operations to reduce fuel use and improve the catch efficiency per unit effort.

Certain types of rattle reels include a housing; a reel coupled to the housing; and an indicator arrangement carried by the housing. The indicator arrangement is operationally coupled to the reel so that movement of the reel relative to the housing activates the indicator arrangement. The indicator arrangement remains activated until the user manually resets the indicator arrangement. Certain types of rattle reels include a free-standing housing including an adjustable leg; a reel coupled to the housing; a power source carried by the housing; a light source carried by the housing; and a user interface member accessible for activating and deactivating the light source.

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.

An illuminated-heated ice fishing system. The system includes a plurality of sidewalls and a top wall in hinged communication and wherein the device is capable of folding up for storage. The system includes a heated lantern to heat and illuminate a spool of the device. The spool is removably affixed to a sidewall of the device and includes a reflective surface directed towards the interior of the device to reflect the light from the lantern. The sidewalls have a bottom portion comprised of a thermoplastic material for contacting the ice surface.
