Sonar

Sonar (SOund NAvigation and Ranging) is a simple way to detect wrecks. It uses sound pulses/echoes, it is inexpensive and can be fitted in small boats. Modern systems can be combined with GPS. A split-screen function allows for detail studies while keeping the overview. Some sonars are sediment-penetrating, revealing objects below the seabottom. Im

SONAR

an acronym for sound navigation and ranging equipment. SONAR systems use sound waves to detect underwater objects by listening to the returning echoes. The distance to the object or the seafloor can be calculated by measuring the time between when the signal is sent out and when the reflected sound, or echo, is received.

sonar

Method of locating underwater objects by the reflection of ultrasonic waves. The time taken for an acoustic beam to travel to the object and back to the source enables the distance to be found since the velocity of sound in water is known. Sonar devices, or echo sounders, were developed in 1920, and are the commonest means of underwater navigation
