the signal to drop to a lower level but not necessarily end. Either the
speaker or the LED signal indicators on the receiver will indicate this
drop.
Be sure the cable or wire you are tracking is associated with a ground
return path, usually by being insulated, but buried in the earth – this
completes a 'loop' for tracing current signal. Ground 'return' paths can
be mechanical meaning a direct physical ground at one end while
capacitive grounding generally applies to cable buried in the earth.
The signal needs a path to return to the ground stake and without it,
you will not get a good locate. A poor ground is indicated when
transmitter signal LED doesn't come on at full power. In most cases, a
direct buried cable fault will provide this grounding and allow for a
cable to be located.
A general rule is the greater the damage to a cable, the greater the
drop off in signal at the point of damage. Conversely, minimal damage
or weak grounding will show little change. This is an art and small
faults are sometimes difficult to locate. Practice and experience will
help immensely in this task.
If the damage is too small to locate and has a path to ground, consider
using a ground fault locator like the GFL3000. Small damage to cables,
like shovel nicks or gopher chews, can be difficult to locate with a
locator. Ground fault locators are designed to find exactly that kind of
fault. More information on ground fault locating and the GFL3000 can
