A fish finder system for a vessel is provided with an interface to connect with a transducer configured to transmit an ultrasonic signal into a water body and receive a reflected echo signal, and an autopilot device configured to control a rudder being attached to the vessel. Further, the fish finder system is provided with processing circuitry communicatively coupled to the interface and configured to detect a position of a fishing rig, measure a vector from the vessel to the fishing rig, and generate a rudder control signal for the autopilot device to control the rudder based on the measured vector.

Fish finder system and method

A fish finder system is provided with a capture device information input terminal configured to input a capture device information, a capture device dropping point input terminal configured to input a dropping point at which a capture device is dropped, a tidal current input terminal configured to input tidal current information including a tidal current direction and a tidal current speed, and processing circuitry communicatively coupled to the capture device information input terminal, the capture device dropping point input terminal, and the tidal current input terminal. The processing circuitry is configured to calculate a drift amount of the capture device relative to the dropping point and calculate a capture device arrival point at which the capture device arrives in the water.

A route setting device is provided, which may include a display controller, a user interface device, a waypoint detecting module, and a route setting module. The display controller having a display screen may display map data on the display screen. The user interface device may accept a route input operation using the display screen where the map data is displayed. Processing circuitry may detect a waypoint of a ship in the map data based on a trace of the route input operation in the map data. The processing circuitry may set a route of the ship based on the waypoint.

Route setting device, automatic pilot, and method of setting route

This disclosure provide a bottom sediment determining device, which is inputted with an echo signal corresponding to an ultrasonic wave outputted underwater, and determines water bottom sediment using a neural network. The device includes a memory for storing two or more parameters to be used in the neural network so as to be associated with positional information, a receiver for receiving the positional information, an acquisition module for acquiring the parameters corresponding to the positional information, and a setting module for setting the parameters to the neural network.
