Product Design Principle: Designed by using principle that the density change of the substance below the surface of the detected object causes the detector frequency to change..Instructions: Just put the detector on tested surface, light up red LED and green LED, and hear "beep" sound. When red LED goes out, the sampling is normal. If the first red LED and the "beep" sound continue to light, the sampling failed..Light Indicator and Audio Alarm: When detecting the location of metal or wood, the detector has an audible and flashing alarm, suitable for use in interior decoration structures, it can detect the position of metal and wood in the wall..Durable Materials: Stud finder wall scanner, selected high-quality plastic materials, durable in use and wear-resistant. Hand-held metal detector, small and light, simple and convenient operation, long service life..Stable Characteristics: Strictly in line with product production standards, professional manufacturing, fine workmanship, reliable quality, stable performance, safety and reliability, worthy of your trust.
