the higher sensitivity range the detector will be sensitive to the electromagnetic
interference that comes from the power lines or cables around and it will be abnormal
to the mineralization soil or electrical conductivity soil. If you move the search coil in
the detection area and the detector always sends a false unstable signal or there is no
metal objects in the soil, please decrease the sensitivity.
4. Move the search coil
When moving the search coil you should move it at a constant speed and not in
an unsteady motion.
Figure.15
Let the search coil be parallel and about 1/2 inch from the surface. Do not swing
it like a pendulum high and low above the ground.( Figure.15,16)
Figure.16
Most valuable metal objects could send repeatable signals. If the signal can’t be
repeated, it’s probably false. You could also move the search coil above the target
objects fast in order to get a more stable signal. When there is a clear sound
instructing that there are buried targets you can make use of the “DISC” button to
determine the metal type. Please note such judgment isn’t accurate and just for
reference to decide whether to dig it out or not. Be careful not to miss any treasure.
5. PINPOINT
When searching in the motion mode you should persistently move the search coil.
When you find the region of the buried metals, it will become harder to find the exact
location of the metallic objects. At this time you should recur to the no-motion mode.
a. Hold the search coil 2 inches from the ground, press and hold down the TARGET
red button and the unit enters the no-motion mode.
b. Let the search coil approach the ground without any metals. If the unit sounds a
