Product overview
This instrument can detect metals (rebars, copper pipes) hidden in walls, ceilings and floors, live wires, Rib and Slot position under wooden walls, etc. It is widely used in interior decoration, home installation and other industries, allowing various construction safely proceed

Operating instructions
Power
Power on, when the instrument is off, press and hold for 1 second to power on.
Power off, when the instrument is turned on, press and hold for 1 second to
turn off
Metal detection mode
Boot into metal detection mode by default. In the non-metal detection mode, short press the to enter the metal detection mode; it has the functions of locating metal, depth indication, and identifying metal properties. It is used to detect magnetic and nonmagnetic metal, and not affected by the characteristics of the wall.
- Step 1: Properly hold the instrument close to the area to be measured, and move the instrument slowly in the area to be measured. When the instrument detects a magnetic metal or non-magnetic metal, the screen displays “metal”, attribute icon, strength of the received signal, and target metal distance instrument depth information. When the sound is on, the instrument will make a “di” sound after it shows “metal”. The closer the detected target metal is to the instrument, the stronger the signal, and the more rapid of the sound.
- Step 2: Center judgment. Move the instrument slowly, when the signal is stronger, it means the detected target metal is closer to the sensing area of the instrument. When the signal reaches a certain intensity or the strongest, the center mark of the screen base lights up, and the target metal is positioned below the sensing area of the instrument.
After detecting the metal, you can also move slowly through different directions and use the signal bar to become stronger to weaker to stronger to locate the target metal position.
AC detection mode
In the non-AC detection mode, short press the to enter the AC detection mode.
This mode is only suitable for scanning live wires. Properly hold the
instrument close to the area to be tested. If found the wired wire, live icon
and the received signal strength will appear on the display. When the sound is
turned on, the “AC” will be broadcast followed by a “di” sound; there must be
more detect the change location back and forth in order to determine the
location of the live wire. The closer the instrument is to the live wire, the
stronger the signal and the more rapid of the sound.
Wooden wall detection mode
In the non-wood wall detection mode, short press the to enter the wooden wall
detection mode; the wooden wall detection mode is mainly used to detect the
uniformity of the wood wall, such as identifying hidden rib and slot position.
There are two operation modes for wooden wall detection: Automatic calibration
detection mode and Manual calibration detection mode.
Automatic calibration detection mode
- Step 1 : Place the instrument close to the target surface to be detected according to the hand-held schematic diagram, and the instrument will perform automatic calibration. After the calibration of the instrument is completed, move the instrument slowly in the area to be measured. When the material change or others such as rib or slot position is detected, The screen displays information such as “RIB” or “SLOT” and the strength of the received signal. When the sound is turned on, the instrument will emit a “didi” sound after broadcasting “RIB” or “SLOT”. when the sensing area of the instrument is closer to rib or slot position and material changes or others. The stronger the sound, the faster the “Didi” sound.
- Step 2 : Center judgment, Move the instrument slowly, when the signal reaches a certain intensity, it means it has reached the target center position, and the center mark of the screen lights up.
- Step 3 : Lift the instrument to terminate the scanning detection and enter the interface to be calibrated. Close to the surface of the detected target again, recalibration and detection can be performed
Manual calibration detection mode
Enter the wooden wall detection mode, the default is the automatic calibration
detection mode. After close to the surface of the detected target, if the
color of the detected target surface is dark and cannot be calibrated, short
press the to enter the manual calibration detection mode to force the
instrument to calibrate. After the calibration is completed, slowly move the
instrument in the area to be measured and scanning detection. In the manual
calibration detection mode, short press the again to exit and return to the
automatic calibration detection mode.
Note:
- The principle of wooden wall detection is to distinguish the uniformity of the material between the calibration location area and other detection areas, which is presented in the form of rib and slot position, that is, solid and hollow.
- If presses the “wood ” to enter the manual calibration detection mode process, the hand leaves the sensing area of the instrument quickly.
System setting
Short press to enter the system setting interface, the system setting interface can set the detection sensitivity of the instrument, calibrate the metal detection mode and view the signal version information of the instrument
Set sensitivity
Short press to select the sensitivity setting, short press to enter the
sensitivity setting interface, you can set the sensitivity of the three
detection modes separately, in the sensitivity setting interface, short press
the to select the setting item, short press to adjust the sensitivity, short
press to return
Metal detection mode calibration
Large-scale changes in the temperature or humidity of the environment where
the instrument is located will cause false alarms in metal detection or
shorten detection depth Short press to select metal detection mode
calibration, short press to enter the calibration interface, short press to
start calibration, and short press to exit the calibration interface after the
calibration is completed.
Note : When calibrating, please make sure that there is no interference of metal and strong magnetic field around(such as lifting in the air) press the to calibration. If the calibration process fails, please recalibrate.

instrument model, software version, and hardware version information on this
interface. Short press to exit.
