FLOAT FOR FISH GROUP CONFIRMATION USING ULTRASONIC WAVES FOR CATCHING LOT OF FISH BY LETTING KNOW AREAS WHERE FISH IS ABUNDANT

摘要

PURPOSE: A float for a fish group confirmation using ultrasonic waves is provided to catch a lot of fish by letting know the areas where fish is abundant. CONSTITUTION: The float(1) is constructed by forming a battery chamber for inserting a battery(5) into a float body(2) and fixing a light emitting diode(4) to a cap(3) arranged to be coupled to the float body(2). An ultrasonic sensor(7) is fixed to the underside of the float body(2) and connected to a PCB circuit board(6) by a wire so that the light emitting diode(4) is flashed on when a fish group exists within an ultrasonic beam(8).
