Fulai 3-in-1 Metal, Live Wire, and Through-Wall Detector: Automatic calibration
This 3-in-1 wall scanner is for the DIY homeowner tackling weekend projects. While many detectors focus on basic metal finding, this tool offers peace of mind for safe renovations by identifying live wiring before you drill.
The large color screen clearly shows depth readings, so you can avoid hitting pipes or electrical lines. It detects magnetic metal up to 120 mm deep and non-magnetic metal to 80 mm, with automatic calibration for quick setup. Use the sound alarm or turn it off for quiet work. The backlit display stays readable in dim spaces, and it runs on a standard 9V battery for up to 6 hours. Keep your home secure and your projects on track with this reliable scanner.
