Classification: CPC G | IPC G

Claim 20:
21. A fish finder system, comprising:
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 from a water surface;
a tidal current input terminal configured to input tidal current information including a tidal current direction and a tidal current speed, wherein area of the tidal current includes the dropping point; 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, and configured to:
calculate a drift amount of the capture device relative to the dropping point, based at least on the capture device information and the tidal current information;
calculate a capture device arrival point at which the capture device arrives in the water, based at least on the dropping point and the drift amount;
output data related to the capture device arrival point; and
input a drift data including a direction and a distance of an actual arrival point of the capture device relative to the dropping point, wherein

the processing circuitry includes an arrival point calculator having:
a neural network with the capture device information, the dropping point, and the tidal current information, as an input data, and a result of drift amount of the capture device as a drift output data; and
a machine learning assembly configured to train the neural network for the drift output data by using actual values of the input data as a training data, and configured to:
enter the input data to the neural network learned by the machine learning assembly as a reference;
calculate the capture device arrival point based at least on the dropping point and the drift amount; and
output the capture device arrival point data.
