An underwater detection device includes a transmitter, a receiver, an actuator, a controller, and a signal processor. The transmitter transmits a transmission wave. The receiver receives a reflection wave of the transmission wave. The actuator rotates the transmitter and the receiver in a mutually synchronized fashion. The controller makes the transmitter transmit a plurality of transmission waves at mutually different frequencies in order, for every given unit rotation angle. The signal processor generates an echo signal for indication in a direction of the unit rotation angle based on a reception signal at each of the frequencies acquired from a range of the unit rotation angle.

In the present invention, an estimator for estimating the number of fish present in an underwater space is constructed by means of machine learning using, as teaching data, a plurality of data sets for learning that each include an echo image for learning, the echo image being based on received sound waves reflected by fish when sound waves are transmitted in an underwater space where fish are present, and the number of fish present in the underwater space in the echo image. The plurality of data sets for learning each include: an echo image for learning that is based on received sound waves reflected by fish when sound waves are transmitted in the underwater space where fish are present; and the number of fish present in the underwater space in the echo image. The estimator is used on an echo image generated on the basis of received sound waves reflected by an unknown number of fish present in the underwater space after transmitting sound waves in the underwater space, so as to calculate the number of said unknown number of fish present in the underwater space.

A system is provided for imaging an underwater environment. The system includes one or more arrays of transducer elements. Each array is operated at a fixed phase shift and varies in frequency so as to beamform multiple sonar return beams of a first range of angles and a second range of angles. The arrays can be oriented to cover the gap in sonar coverage for other arrays to create a continuous arc of sonar coverage. Accordingly, a 2D live sonar image can be formed. One or more of the multiple sonar return beams facing downwardly can be selected and used to form downward sonar images that anglers are used to, without requiring separate transducer elements. Fish arches formed using multiple sonar return beams can be positioned appropriately within a high resolution downward sonar image to form a desirable combined sonar image.

A fish finder transducer mount apparatus for independently controlling a directional transducer and trolling motor includes a clamp body. A motor clamp is coupled to the clamp body. The motor clamp is selectively engageable with the clamp body and configured to secure the apparatus to a propeller shaft of a trolling motor. A directional transducer shaft is rotatably coupled to the clamp body and a directional transducer shaft bottom end of the directional transducer shaft to receive a directional transducer of a fish finder. A gearing system is coupled to the directional transducer shaft to rotate the directional transducer shaft. A handle is coupled to the gearing system. The handle comprises an extension portion secured by a user to manipulate the orientation of the directional transducer shaft.

A system and method for tracking marine equipment is provided. Generally, the system and method of the present disclosure are designed to generate indicia corresponding to the inventory level of marine equipment used for a particular marine activity. To facilitate the assignment of indicia reflecting the inventory level of marine equipment used for a marine activity, the system and method of the present disclosure uses a plurality of equipment profiles having a defined lower limit and quantity associated with each piece of marine equipment. The lower limit may be manually input or automatically generated. The quantity may be tracked by the system using equipment transmitters and equipment sensors. In a preferred embodiment, the indicia indicate whether the quantity of a piece of marine equipment has fallen below a certain specified level as defined by the user. Users may purchase new marine equipment from third-party retailers via the user interface.

A method of dynamically reconfiguring sensor system operating parameter by receiving, at an electronic device, data indicative of one or more underwater object parameters corresponding to one or more underwater objects within a marine enclosure. A set of intrinsic operating parameters for a sensor system at a position within the marine enclosure is determined based at least in part on the data indicative of one or more underwater object parameters. The sensor system is configured according to the determined set of intrinsic operating parameters by changing at least one intrinsic operating parameter of the sensor system in response to the data indicative of one or more underwater object parameters.
