When the detector detects a buried target, it sounds a tone. User can make a
visual note of exact spot on the ground where the detector beeps.
Then stop the search coil directly over this point on the ground. Move the
search coil straight forward away from you and straight back towards you a
couple of times. Meantime slowly rotate the DISC control clockwise away from
ALL METAL until the unit does not sound or sounds short tone. You can identify
what kind of metal is rejected according to the setting position of DISC.
A reference for you to know what kind of metal is rejected depending on the
DISC setting.

FACTORS THAT AFFECT THE DETECTING
It's difficult to have an accurate detecting result. It needs practice to get better
detection results. Sometimes the detecting may be restricted by some factors:
•
If there are interference from other instruments or electrical cable or TV or
radio in your searching area, lower the sensitivity, or to change the current
searching area.
•
When searching in highly mineralized area, the unit will sound even if
there's no metal. In this case, you can lower the sensitivity and increase the
height between the search coil and the ground until the false signal
disappears. If necessary, reset the DISC.
•
When searching in trash area, it's better to set the DISC to 11:00 position,
so that the unit can notch most of invaluable metals such as nails and small
trashy iron. Move away any metal digging tool when searching.
•
Sensitivity level is generally in contradiction with that of the Discrimination.
The higher the sensitivity level is, the worse discrimination will be. But you
can lower the sensitivity to have better.
