2 How Sonar W orks How Sonar W orks Sonar technology is based on sound waves. The 500 Series™ Fishfinder uses sonar to loca te and define structure, bottom contour and composition, as well as depth directly below the transducer .
3 When all the echoes are viewed side by side, an easy to interpret “graph“ of the bottom, fish, and structure appears. The soun d pulse s are transm itte d at var ious frequencies depending on the application. V ery high frequencies (455 kHz) ar e used for grea test definition but the opera ting depth is limited.
4 DualBeam PLUS™ Sonar (DualBeam PLUS ™ models only [586c HD, 596c HD]) Y our 5 86c HD/5 96c H D Fish fin der use s a 200/83 kHz DualBeam PLUS™ sonar system with a wide (60°) area of co verage.
Down Imaging™ Sonar (Down Imaging ™ models only [596c HD DI, XNT 9-DI- T T ransducer]) Y our 596c HD DI F ishfinder uses Do wn Im ag in g™ te ch no log y . The Dow n Imaging™ transducer scans the w ater with raz or-t hi n, hi gh -d efi ni ti on be am s.
