OPERATION
STANCE
•Stand with your arm extended in
front of your body. Hold the search
coil off the ground, 1/2 to 1 inch
above the surface.
•Position the search coil parallel to the
ground.
SWEEP
•Swing the coil slowly, from side to
side. The coil must be in motion to
detect metal.
•Maintain the coil parallel to the
ground. Do not raise the coil at the
end of each sweep.
•Move slowly and overlap each
sweep as you move forward,
sweeping the coil in half-circle
movements.
•The coil must be in motion to detect
metal. Your Surveyor incorporates
motion detection technology. A
motionless search coil will not detect
buried objects.
TARGET RESPONSE
Most desirable targets will induce
repeatable tones. When the detector
emits a tone, pass the coil over the
same spot again, and listen for a
consistent repeatable tone each time
the coil passes over the target zone.
Broken tones and non-repeatable
tones
usually indicate the presence of
trash or irregularly shaped objects.
Electromagnetic interference (EMI)
can cause false, or non-repeatable,
signals. EMI is emitted by power lines
(overhead or buried), other detectors
(keep 2 detectors 20 feet apart), or by
machinery and motors.
