Sweep the Area for Conductors

Maintain a constant distance between the Receiver and the

Transmitter. Move together across the area where the conduc-

tors are suspected to run. DO NOT adjust the sensitivity during

the sweep. When the operators sweep together over a conduc-

tor, the tone from the Receiver will get HIGH (shrill) or begin

beeping, indicating a stronger signal. Temporarily mark the high

pitch areas for pinpointing later.

Pinpoint and Determine Signal Source

Set the Transmitter down in one of the high pitch areas found,

and pinpoint with the receiver (page 11). After checking direc-

tion, get a good solid tone on the receiver and let the other per-

son pinpoint using the transmitter. Move the transmitter left and

right until the receiver gets the strongest (highest pitch) signal

response. At this point the Transmitter and receiver are directly

over the conductor.

After pinpointing the conductor, raise the receiver toward the

transmitter to be sure the signal is mostly coming from the con-

ductor and not through the air, as described on page 13.

Conductors Going in Different Directions

Set up as before in different directions to sweep the area for con-

ductors running at 45° and 90° to the original locating position.
