How to Locate Buried Electrical Wires With a Metal …

A metal detector is often used for much more than just finding treasure. The advanced circuitry in these machines is custom-tailored to find specific types of metallic items. When locating underground wires, the signal from the metal detector easily penetrates plastic conduit and detects the metallic wire inside. If the conduit is metal, this makes the process even easier.

When first introduced approximately 40 years ago, underground locators needed to do little more than find buried water, gas, or sewer lines. Today, locating has become more complex as telecommunications cables join utility lines in the underground environment. Surprisingly, though, today`s underground cable locators rely on the same basic technology found in their early counterparts--injecting ...

Cable Detection, Cable Location & Cable …

Buried cables and underground services are missed when the cable detector operator has been pinpointing a service with a shallow signal and manually adjusts the cable locator to minimise its reception so that the centre of the cable service can be located. If the cable locator moves on to scan a new location the operator may forget to turn the sensitivity to full power - consequently if there ...
