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.

The present invention is directed to an improved fishing rod guide. In one embodiment the improved fishing rod includes superhydrophobic metal guides. The superhydrophobic metal guides make it possible for fishing line, including, for example, fly fishing line and conventional fishing line, to move through the guides with less weight and drag due to water and ice accumulation, allowing for significantly greater distance and ease in casting. Additionally, the decrease in friction between the fishing line and line guides help extend the life of the fishing line.

The present invention relates to a novel bottom bouncer device. The device is designed to provide fishermen with lead-free bait at an elevated level above the bottom surface. Specifically, the bottom bouncer device is configured for a fishing rod and is both lead-free and weedless. The device comprises a round, brass rod with a split ring at the top and a snap swivel attached to the split ring. Further, the bottom nine inches of the rod may be turned down in a lathe to produce differing weights for the bottom bouncer device.

The present invention relates to a fishing leader device comprised of a line, at least one hook, at least one weight, and at least one leader attachment member. The weight is positioned at the bottom of the leader above the hook to allow the hook and the leader to be pulled downward toward the bottom of a body of water to prevent tangles and snags. The device is also comprised of at least one bead that can attract fish, as well as protect the connection members from fish biting which can weaken the fastening.

a fishing vibrator that is configured to be mounted on a fishing pole when fishing. The fishing vibrator comprises of a housing, a battery that is housed within the housing, a vibrating motor that is housed in the housing, the vibrating motor is operatively connected to the battery; an offset flywheel that is attached to the vibrating motor, a switch that is attached to the housing, a pair of u-shape pole rubber attachments that are used to attach the housing to the fishing pole, and a hook and loop system that is used to attach the housing to the fishing pole.

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.
