Meet the Walabot DIY 2 for iPhone and Android: a WiFi-enabled visual stud finder that gives you x-ray vision into your wall for safe drilling. It keeps you from accidentally drilling into pipes or wires. It has a completely wireless design and can work at a distance from your phone.
The device uses 4D RF technology to see 4 inches into drywall. It has Images and Export mode, with the former giving you a full visual of the pipes, wires, and studs.
