Claims

[Scope of utility model registration request]

The weighing fish finder outputs two low-frequency echo voltage signals in parallel with a certain rest time in between.
In addition to the high-frequency echo voltage signals of the systems, the low-frequency echo voltage signals and high-frequency echo voltage signals of the two systems are time-series based on inputs of various parameter information output in parallel by the weighing fish finder and the navigation instruments. forming two data channels in which a low-frequency echo voltage signal and a high-frequency echo voltage signal repeat in between the predetermined pause times, and inserting a recording synchronization signal into the pause time of at least one of the data channels, and inserting a recording synchronization signal into the pause time of at least one of the data channels; a recording converter for chronologically arranging and sequentially inserting the various parameters during the rest time of the data channels; a data recorder for receiving the output of the recording converter and recording each signal of the two data channels; ; Reproducing each signal of the two data channels from the data recorder in parallel, and outputting the two systems of low frequency echo voltage signals, the two systems of high frequency echo voltage signals and the various parameter information, respectively. A data recording device for a weighing fish finder, comprising: a converter for reproduction; and;
