6. Operating Instructions
6.1. Power On/Off
- Press the ON/OFF button to turn the device on. The LCD will illuminate.
- Press the ON/OFF button again to turn the device off.
6.2. Selecting a Scan Mode
After powering on, press the ► (mode selection) button to cycle through the available detection modes: STUD, METAL, DEEP, and AC. The selected mode will be indicated on the LCD display.
6.3. Scanning Procedure
- Place the device: Position the scanner flat against the surface you wish to scan. Ensure the sensor area on the back is in full contact.
- Press and Hold 'PUSH': While keeping the device flat against the surface, press and hold the PUSH button located on the side. The device will calibrate for a few seconds. Do not move the device during calibration.
- Scan the surface: Slowly slide the device horizontally across the surface. Keep it flat and maintain constant pressure.
- Interpret results: As the device detects an object, the signal strength bars on the LCD will increase, and an audible beep will sound. The specific mode indicator (STUD, METAL, DEEP, AC) will also highlight.
- Mark the location: When the signal strength is highest, mark the location. Continue scanning past the object to determine its edges.

Figure 6.1: Examples of detection modes. This image shows three scenarios: AC detection near an electrical outlet, Stud detection locating a wooden beam, and Metal detection identifying a metal pipe within a wall.

Figure 6.2: Detection indication. This image illustrates the device detecting an object, with the LCD displaying a series of arrowheads and an audible 'Beep!' indicating a find. The user is shown pressing the 'PUSH' button during detection.
6.4. Specific Mode Usage
- Stud Scan: Use to locate the edges and center of wooden studs behind drywall.
- Metal Scan: Use to detect metal pipes, rebar, or other metallic objects.
- Deep Scan: Provides increased depth for detecting studs and metal objects that are further embedded in the wall.
- AC Scan: Specifically designed to detect live unshielded AC electrical wiring. Always confirm power is off before any work.
7. Maintenance
- Cleaning: Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a dry, cool place, away from direct sunlight and extreme temperatures.
- Battery: Remove the battery if the device is not used for extended periods to prevent corrosion.
8. Troubleshooting
- Device does not power on: Check battery installation and ensure the battery has sufficient charge. Replace if necessary.
- Inaccurate readings/False positives: Ensure the device is calibrated correctly by pressing and holding the PUSH button while flat against the surface before scanning. Avoid scanning over highly textured or damp surfaces.
- No detection: Verify the correct mode is selected for the target material. Ensure the device is moved slowly and consistently across the surface.
- Weak signal: The object might be deeper than the selected mode's detection capability. Try the Deep Scan mode if applicable.
