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.
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
(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.
