What is the Function of Sondes in Utility Locating?

Sondes play a crucial role in the accurate mapping and inspection of underground utilities. These devices are typically embedded in robotic crawlers or push cameras used within pipelines or sewer systems. Their primary function is to generate an electromagnetic field, which can be detected by electromagnetic (EM) locators or sonde locators on the surface.

This capability allows professionals to precisely determine the location of underground sewer lines and other utilities. By employing sondes, utility locating and video pipe inspections become far more efficient and reliable, providing project managers with essential information needed to map utilities accurately and prevent potential infrastructural issues.
