How Sonar Works

Sonar technology is based on sound waves. The Humminbird® FishFinder uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer.

Your FishFinder sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object; it then uses the reflected signal to interpret location, size, and composition of an object.

Sonar is very fast. A sound wave can travel from the surface to a depth of 240 ft (70 m) and back again in less than ¹⁄₄ of a second. It is unlikely that your boat can "outrun" this sonar signal.

Single Beam Sonar

Your Humminbird® FishFinder 585c uses a 200 kHz single beam sonar system with a 20° area of coverage. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation.
