Classification: CPC G | IPC G

Claim 0:
1. 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; and
output data related to the capture device arrival point, wherein

the capture device information includes a size of the capture device, a weight of the capture device, and a fishing line length from the dropping point to a tip of a fishing line to which the capture device is attached, in the water, and
the processing circuitry is further configured to calculate the drift amount within reach of the tip, based at least on the size of the capture device, the weight of the capture device, and the tidal current information.
