How Sonar W orks Sonar technology is based on sound wav es. The 700 Series™ Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly belo w the transducer . Y our 700 Series™ Fishing System sends a sound wav e signal and determines distance by measuring the time between the tr ansmissio[...]

2 The sound pulses ar e transmitted at various frequencies depending on the application. V ery high frequencies (455kHz) are used f or greatest definition but the operating depth is limited. High frequencies (200kHz) are commonly used on consumer sonar and provide a good balance between depth performance and r esolution. Low frequencies (83kHz) are[...]

3 DualBeam PLUS™ Sonar Y our 700 Series™ Fishing System uses a 200/83 kHz DualBeam PLUS™ sonar system with a wide (60°) area of cov erage. DualBeam PLUS™ sonar has a narrowly f ocused 20° center beam, surrounded by a second beam of 60°, expanding your cov erage to an area equal to your depth. In 20 f eet of water , the wider beam cover s[...]
