The indication that the receiver gives which is caused by the signals it 

is receiving. This can be visual, audio or both. Typically it is displayed 

on the locators dot matrix display and audibly from a loudspeaker in 

the receiver housing.

This describes the act of looking for a buried line within a given area.

A small transmitting coil which may be built into a product such as a 

sewer camera or packaged as a small self contained battery powered 

transmitter. A receiver tuned to the same frequency can locate the 

position of the Sonde and hence whatever it is attached to or in. 

Frequently used for locating sewer cameras, and the non metallic 

pipes.

The buried pipe or cable to be located.

Using a locator to following the path of a buried line.
