This method is convenient to use, and services are not interrupted. No test cords or connections
are needed. The cable or pipe must have good insulation or non-conductive coating, or the
operating range will be short.
Turn the
T
ransmiTTer
ON. Select 33kHz through 478 kHz.
Place
t
ranSmItter
on
ItS
SIDe
as close as
possible to the path of the cable or pipe. Align the ARROWS on the SIDE OF THE TRANSMITTER
in line with the cable or pipe. First, locate the broad
T
ransmiTTer
Null, then move toward the
expected cable path while looking for the signal carried by the cable.
Start tracing the path with the
r
eceiver
25 feet from the
T
ransmiTTer
. Search in the 90º zone as
shown above. Locate the cable or pipe, and follow the path. If the signal becomes weak, move
the
T
ransmiTTer
to a point 25 feet behind the last strong signal, and continue searching.
The Blind Search locating techniques is used if the operator is not aware if a buried utility exists.
Two people are needed for this technique. The
T
ransmiTTer
and the
r
eceiver
are Held 25 feet away
from each other. Each operator walks at the same speed keeping a distance of 25 feet from
each other. When the receiver gives an audio response, then a buried utility is present between
the
r
eceiver
and the
T
ransmiTTer
.
