Electronic Marker Locators provides an accurate, convenient, long-lasting method of marking underground facilities. Electronic marking eliminates time and money spent searching for “lost” facilities. The marker also acts as a digging shield over buried facilities, lessening the chances of a costly dig-in. And, unlike surface markers such as stakes, flags or paint, the full-range marker cannot be inadvertently removed or worn away by weather. The full-range marker is buried over key facilities during construction or maintenance. Later, the marker is easily and accurately located using a EMS II Marker Locator, which consists of a compact electronics package and a lightweight hand-held probe. The locator transmits a signal to the buried marker. The marker reflects the signal back to the locator, and its exact location is indicated with both a visual meter reading and an audible tone.
