A sound wave emission system includes a substrate, a sound wave device, and a power source. The sound wave device is mounted on the substrate and configured to emit sound waves. The power source is mounted on the substrate and electrically coupled to the sound wave device. The volume, rhythm, and duration of the sound waves emitted by the sound wave device are controlled to simulate sounds of different kinds of fish in different situations.

A fishing bobber apparatus for controlled hook depth and improved fishing includes a float having a float aperture centrally extending from a top end of a head portion through a neck portion and a body portion. The float is buoyant. A chamber is coupled to the float. A base weight is coupled to the chamber. A base inner side is funnel-shaped and has a central base aperture. A rigid line tube is coupled to the float. A pinch tube is coupled to the line tube. The line tube and the pinch tube are configured to slidably receive a fishing line. The pinch tube is malleable and configured to secure the fishing line in place when pinched. A weight ball is coupled within the chamber. The weight ball rests on the base inner side and pinches the pinch tube when the apparatus is in an upright position.

A fishing bobber is comprised of a hollow casing, a plug, a weight, a straw and a visibility marker. A weight is captively held moveably inside the hollow casing between one semi-closed end of the casing and a plug telescopically engaged with the other end of the casing. A straw extends through the center of the plug and communicates with the hollow of the casing and then extends to the distal end of the bobber where it is adorned with a visibility marker. A fishing line can be threaded from a fishing pole through the semi-closed end of the casing, through the hollow cavity in the casing, and out through the straw on the distal end of the bobber where a sinker and hook can be located on the fishing line. The hook is located a predetermined distance from the end of the line attached to the sinker. When the fishing bobber assembly is in the horizontal position on the surface of the water the weighted end of the fishing line will freely pull the line from the pole through the fishing bobber assembly until the weight lands on the bed of the fishing spot. A perforation in the middle of the casing allows water to enter the initially air filled hollow of the casing causing the fishing bobber assembly to gradually change from a horizontal position toward a vertical position. The change of position of the bobber rom horizontal to vertical causes the moveable weight to bottom against the semi-closed end of the casing and stops the free movement of the fishing line, which then which then puts tension on the fishing line between the weight on the fishing bed and the vertical positioned bobber.

A lure strike indicating assembly for preventing obstruction of rod guides includes an indicator, a filament, and a coupler. The filament is coupled to and extends between the indicator and the coupler. The coupler is configured to slidably couple to a fishing line. A fastener is coupled to the indicator. The fastener is configured to selectively couple to the coupler and the fishing line so that the indicator is fixedly positioned relative to a lure that is coupled to an end of the fishing line. The fastener also is configured to decouple from the coupler and the fishing line in the event of a strike on the lure. The coupler is slidably positionable relative to the lure to prevent the indicator from obstructing a guide on a tip of a fishing rod to which the fishing line is coupled as the fishing line is retracted into a reel.

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.
