Locating cables connected to a grounded object 

To locate a cable connected to a grounded 
object, connect one SG33 output to the 
object itself. Ground the second output in 
the opposite direction from the located 
cable with a grounding rod as far as 
possible. If soil is inaccessible, ground the 
second output to another nearby grounded 
object that is not connected to the located 
cable. 
Boost mode is recommended if the other 
end of the cable has poor or no connection 
to ground or the soil is dry. It is possible to locate multiple cables connected to the same 
grounded object with this method.
