SEARCH AND SWEEP

One Person

This technique is beneficial in finding conductors with unknown
locations, and with no access points. Basically you use the
equipment in a way that scans the entire ground to find all con-
ductors in a specific area. Please read the instructions for induc-
tive locating before proceeding.
Position the Transmitter
Lay the 800-H Transmitter on its side, as shown below. This will
"flood" the area with signal. Turn ON the Transmitter.
Set Up the Receiver
Set up with the Receiver the same as you would during inductive
locating. Move 5-10 feet from the Transmitter, face the Trans-
mitter with the antenna near the ground, and turn the Receiver
ON. Set the sensitivity control so that the meter reads 4 and
you hear a LOW pitched tone.
Locate the Conductor(s)
With the receiver facing the Transmitter, walk in a circle around
the Transmitter. Keep a steady distance from the Transmitter
and from the ground. Listen for the HIGH pitch tone areas, DO
NOT adjust the sensitivity. After locating the HIGH pitch areas,
go back and pin-point the conductors in those areas. You may
need to re-adjust the sensitivity at this step, looking for the LOW-
HIGH-LOW sound change. Mark the places with the highest
tones for further pinpointing later.
