A single-beam echo sounder is one of the simplest and most fundamental types of underwater sonar. They are ubiquitous in the boating world and used on a number of different marine robotic vehicles. It operates by using a transducer to emit a pulse through the water and listen for echos to return. Using that data, it's able to determine the distance from the strongest echo, which can be the seafloor, a concrete structure, or other larger obstacle.<ref>{{Cite web |title=A Smooth Operator's Guide to Underwater Sonars and Acoustic Devices |url=https://bluerobotics.com/learn/a-smooth-operators-guide-to-underwater-sonars-and-acoustic-devices/ |access-date=2024-01-12 |website=Blue Robotics |language=en-US}}</ref> A [[fishfinder]] is an echo sounding device used by both recreational and commercial fishers.
