Page 47: Theory Of Fishfinder
17. THEORY OF FISHFINDER ． THEORY OF FISHFINDER ●Theory of fishfinder is same as echo among hills Ultrasonic wave transmitted from the transducer directly beneath the vessel is reflected at the sea bottom and received by transducer. Fishfinder indicates the depth by calculating the round-trip time to distance. Also, the unit shows the color image of fish school size/density or sea floor condition according to the strength of reflected wave. - Page 48 ． Distinguish of Fish School ●Important tip is comparison between fish school image and actual catch Possible to judge the fish type to some extent from the image of fish school. The shape of fish school changes even for same fish group by time(day/night, season, current change).
