Underground Service Locator: How Does it Work?
About 50 years ago, when underground utility locators were first introduced, they didn’t need to find much, except buried server, gas and water lines. Nowadays however, locating underground services has become much more complex, as optic and telecommunications cables have joined the underground utility lines club. But regardless of this fact, today’s service locators still rely on the same technology, and work in a similar concept – sending an electric signal underground and picking it back up through a transmitter once the signal comes across a cable or pipe.
