ABSTRACT:
An improved fish finding device and method for detecting and distinguishing marine life from a sonar reflected marker that generates artificial echoes comprises steps of 1. transmitting of sonar waves 2. receiving of sonar echoes 3. distinguishing the sonar echoes reflected from a sonar reflected marker from the marine life by the difference of frequency, intensity, waveform and duration of the echoes and converting echoes into signal using a microprocessor and 4. displaying the echoes signal of the sonar reflected marker as an icon different from that of the marine life. The relative distance of the sonar reflected marker and the marine life could also be calculated by a microprocessor. A fish nearby alarm sounds when fish swims within a preset value of distance. The improved fish finding device and the fish finding method guide the user to adjust accurately the bait next to fish. The improved fish finding device also alarms the user that fish is nearby the bait when a sonar reflected maker is used and placed next to the bait.
