The SUNMAY Stud Finder Wall Scanner is a multifunctional detection tool designed for accurately locating wood, metal, AC live wires, joists, and pipes behind walls. Its 7-in-1 capability combines several essential detection modes in one compact device, making it suitable for both professional contractors and home DIY enthusiasts. The tool features an HD LCD display that provides clear visual feedback, including depth and edge indicators, to help users identify hidden objects with precision. The detection sensor is calibrated to sense ferrous and non-ferrous metals, wooden studs, and energized electrical cables through standard drywall, plaster, or paneling.

Constructed with a durable ABS plastic housing, the unit is lightweight yet impact-resistant, ensuring reliable performance during repeated use. The internal circuitry employs advanced signal processing to reduce false readings and maintain stable accuracy across different wall densities. The power-saving design automatically shuts off after a period of inactivity, extending battery life. The ergonomic grip and single-hand operation allow for smooth scanning along vertical and horizontal paths.

The tool measures standard stud depths up to 0.75 inches for wood and 1.5 inches for metal, while the AC wire detection function alerts users to live voltage before drilling. The build quality emphasizes long-term reliability with reinforced seams and a scratch-resistant lens covering the display. The on/off sensitivity adjustment helps tailor the detection to thin or thick wall layers, minimizing unnecessary alerts. The device operates on two AAA batteries (not included) and has a low-battery indicator.

Its straightforward interface requires no complex setup—users simply power on, select the target mode, and scan. The compact size allows easy storage in a toolbox or pocket. Priced at an extremely affordable level, this stud finder delivers essential functionality without compromising on core detection capabilities.

It serves as a practical, budget-friendly solution for locating studs for shelf mounting, TV installation, or electrical projects. The versatility of detecting both wood and metal studs, plus live wires, reduces the need for multiple tools. For users seeking a reliable, no-frills wall scanner that offers good value for the cost, this model provides a solid entry-level option.
