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
tranSmItter on. This method of signal application only works on frequencies from 33kHz
through 478 kHz. Place tranSmItter 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
TransmiTTer Null, then move toward the expected cable path while looking for the signal carried by
the cable.
Start tracing the path with the
receiver 25 feet from the tranSmItter. Search in the 90º zone as
shown above. Locate the cable or pipe, and follow the path. If the signal becomes weak, move the
tranSmItter 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
tranSmItter and the reCeIver 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 reCeIver and
the
tranSmItter.
