• Digital LCD Screen: Unlike traditional neon tester screwdrivers, it features a clear digital display that indicates signal strength, sensitivity state, and battery status.

• Dual-Range Sensitivity: Switches between low and high sensitivity settings, enabling detection of standard household mains voltage (100V–300V) as well as low-voltage circuits (12V–48V) such as doorbells, thermostats, and landscape lighting.Test pencil
