Claims

[Scope of utility model registration request]

The transmission pulse sent from the transmitter is converted into an ultrasonic wave by a transducer and emitted into the water, and the ultrasonic echo from the water is converted into an echo signal by the transducer, which is amplified by an amplifier and A/D.
Convert it to a digital echo signal with a converter and store it once.
In a fish finder that performs recording processing or image processing on the stored digital echo signal, stores it in a memory, reads it from the memory, and records or displays it on a recording device or display device, the outputs of the temperature sensor and the PH sensor are each amplified. Then, through a switching circuit, the A/D converter converts the temperature and pH into digital signals, and then stores them.
Performing recording processing or image processing on the stored digital signals of temperature and PH, storing them in the memory, reading them from the memory, and overwriting the digital signals of temperature and PH on the record with a line graph, A fish finder that digitally records or displays a value corresponding to a digital signal of the temperature or PH.
