10. Scanning in metal mode
Metal Scan mode has interactive calibration to suit its sensitivity to the
metal, which can be used to find the precise location of metal objects in
walls, floors and ceilings. Maximum sensitivity is ideal for quickly finding the
approximate location of metal. However sensitivity can be reduced by
calibrating the device closer to metal. When the sensitivity decreases, the
area where metal is indicated will be smaller. In both cases, the metal
target is in the center of the area where the device indicates metal is
present.
For maximum metal sensitivity, turn on the device in the air by
pressing the Scan button, keep the device still before the calibration
has completed. This will ensure that it calibrates away from any
metal objects.
Note: Under metal detecting mode, please make sure that it is far
away from other metals, wires and objects with strong magnetic
field when power on and calibration.

(Figure A) While holding the Scan button, press the device flat against
the wall and slowly slide the device across the surface. Mark the point
where you get the highest metal indication (the most Middle bars on
the screen). If it is a strong target, the top indicated arrow will show,
and a steady beep will sound. Continue in the same direction until
display bars reduce. Reverse direction and mark the spot where the
display bars peak from the reversed direction.
The midpoint of the two marks is the location of the center of the
metal object. If the device indicates metal over a large area, you can
refine the scanning area to more accurately locate the metal target by
following below steps 2 and 3.
