Hi Bob:

I've used the receiver that has two boxes on a horizontal tube where the re=
ar box is vertical and the front box is=20
horizontal.
The transmitter is connected to the cable/pipe where it's above ground.
This system not only allows following the pipe but determining it's depth b=
y tilting the receiver to 45 degrees then=20
moving off the center to maximize the signal.  The distance from the center=
 line is now the depth of the pipe.  When=20
there's crossed pipes/cables the tricky part if figuring out which is the o=
ne you want.

You can find "underground cable locator" on eBay and probably can rent a fa=
ncy one.

Have Fun,

Brooke Clarke
