RECEIVER UNIT
PIPEHORN
GENERAL INFORMATION
The Pipehorn is a carefully engineered, hand-crafted,
precision instrument which, with reasonable care, will give many
years of satisfactory service. It is the finest instrument on the
market today for locating underground or concealed piping, tub-
ing or cable. It is very simple to use but for best results you
should carefully read these instructions and be guided by them.
Since the Pipehorn uses a high frequency electrical cur-
rent, it can only be used to locate metallic structures such as
steel or cast iron pipe, copper or aluminum tubing or wire. It can
be used to find plastic or clay pipe if a wire or metallic tape can
be inserted into the pipe or if a wire was buried with the pipe.
Soil or paving materials such as concrete or asphalt
have little or no effect on the operation of the Pipehorn. How-
ever, reinforced concrete contains a network of metal which will
interfere with the proper operation of the instrument, and it usu-
ally cannot be employed to locate structures underneath or be-
hind reinforced concrete, metal lath or similar materials.
