A wall scanner is a handy tool used to detect objects hidden behind walls, such as studs, pipes, and electrical wires. It helps you locate these objects accurately before drilling or hammering into the wall, preventing damage to your home and potential electrical hazards.

How it works:

Wall scanners typically use a combination of technologies to detect objects:

• Stud Detection: Uses sensors to detect changes in the wall’s density, indicating the presence of a solid object like a stud.
• Metal Detection: Detects metal objects like pipes or electrical wires using electromagnetic sensors.
• AC Wire Detection: Detects live electrical wires by sensing the electromagnetic field they generate.

Key features to look for in a wall scanner:

• Accuracy: The ability to accurately locate objects behind the wall.
• Depth Detection: The ability to detect objects at different depths within the wall.
• Multiple Detection Modes: The ability to detect studs, metal, and live wires.
• Easy-to-Read Display: A clear display that shows the location of objects.
• Ergonomic Design: A comfortable grip and easy-to-use controls.

By using a wall scanner, you can save time, avoid costly mistakes, and ensure a safe and efficient home improvement project.
