2 How Sonar W orks Sonar technology is based on sound wav es. T he 300 Series™ Fishfinder uses sonar to locate and define structur e, bottom contour and composition, as well as depth directly below the tr ansducer .
When all the echoes ar e view ed side by side, an easy to interpret “gr aph“ of the bottom, fish, and structure appear s. The sou nd pu ls es are t rans mi tt ed at var iou s frequencies depending on the applica tion. V ery high frequencies (455 kHz) ar e used for gr eatest definition but the operating depth is limited.
4 DualBeam PLUS™ Sonar (DualBeam PLUS™ models only [345c]) Y ou r 3 4 5c Fishfinder uses a 200/83 kHz DualBeam PLUS™ sonar system with a wide (60°) area of cov erage. DualBeam PL US™ sonar has a narro wly focused 20° center beam, surrounded b y a second beam of 60°, expanding your cov erage to an area equal to your depth.
Down Imaging™ Sonar (Down Imaging™ models only [345c DI]) Y ou r 345c DI Fishfinder uses Down Imaging™ technology . The Dow n Imaging™ transducer scans the w ater with razor -thin, high-definition beams. T he beams are wide (side to side) but very thin front to back.
