Underground Cable Locator
A cable locator is basically an instrument which is deployed to detect presence of any such buried utility services well before performing any excavation activities. It also detects its location of such debris in any property.
A cable locator generally consists of two modules - a transmitter and a receiver. A transmitter is basically an Ac Generator which supplies the signal current to the underground cable to be traced. A receiver detects the electromagnetic field created by the transmitted signal around the cable.
