HOW SONAR WORKS
Sonar uses sound waves to determine the presence of underwater objects. The time measured
between the transmission of the sound wave, and the reception of any reflection can be used to
determine distance. Analysis of the reflected signal can be used to determine location, size,
composition, etc.

Humminbird products consist of two primary
components: the sonar unit and the transducer. The sonar unit contains the transmitter and
receiver, as well as the user controls and display. The transducer is smounted beneath the water
surface and converts electrical energy from the transmitter into mechanical pulses or sound
waves. The transducer also receives the reflected sound waves and converts them back into
electrical signals for the display on the sonar unit.
The transmit and receive cycle is very fast. A sound wave can travel from the surface to a depth
of 240 feet and back again in less than ¼ of a second; so it is unlikely that your boat can “outrun”
this sonar signal.
