Metal Detector - Sensitive Scan is a free Android app developed by sunshine vay. It falls under the category of Utilities & Tools and is designed to detect metal objects using the built-in magnetic field sensor of your smartphone.

The app works by measuring the electromagnetic field (EMF) level around your device. When a metal object such as steel or iron is nearby, the EMF reading increases, accompanied by a beep sound. It can be used to find metal objects like nails, wires, and other metallic items. However, it is important to note that the app cannot detect non-ferrous metals like gold, copper, and silver as they do not have a magnetic field.

If you encounter high readings while using the metal detector, you can easily recalibrate the magnetic field sensor by shaking your phone gently for 4 to 5 times. This ensures accurate detection of metal objects. Metal Detector - Sensitive Scan is an effective tool for scanning ferrous materials and is highly recommended for those in need of a reliable metal scanner.
