How to use

To begin using the scanner, ensure the device is fully charged using the provided USB cable. Power on the unit and select the appropriate detection mode based on the material you are searching for, such as metal, wood, or live wires. Place the scanner flat against the wall surface and move it slowly in a horizontal or vertical motion. The device will provide visual feedback on the color display and audible voice prompts when an object is detected. For laser distance measurements, switch to the measurement mode, aim the laser at the target surface, and press the trigger to obtain an accurate reading.

What to consider before purchase

• Check the wall material compatibility to ensure it meets your specific project needs
• Consider the maximum detection depths for the materials you work with most frequently
• Verify that the laser measurement range is sufficient for your typical room dimensions
• Ensure the device is charged before starting your work session

Usage recommendations

For the most accurate results, calibrate the device on a clear section of the wall before starting your scan. Always perform multiple passes over the area to confirm the location of the detected object before drilling.
