single beam echosounder

A single beam echosounder is a device used primarily in marine and underwater surveying. It sends out a sound pulse, which travels through water until it hits the seabed or underwater objects. The sound wave then bounces back to the device, measuring the time taken for the echo to return. This information allows researchers and navigators to calculate the depth of the water or the contours of the seafloor. It’s commonly used for mapping, fishing, and navigation, providing crucial data for both scientific and practical applications in our oceans and lakes.
