Gold & Metal Detector, Scanner is designed to detect nearby metal by using a device’s built-in sensors, such as its magnetometer, to identify changes in the surrounding magnetic field. The app is presented for locating metal objects, including gold and other buried metal targets, with the device used as a handheld detector that can be swept over an area.

Detecting changes in the magnetic field

The central function is magnetic-field detection. When the app identifies a change associated with a nearby metal object, it displays a visual representation of the magnetic field on the screen. This gives users an on-screen indication to examine while moving the device around a search area.

Adjusting detection and target filtering

Users can adjust the detection sensitivity to suit their search needs. The source describes this control as a way to support more precise detection. Filtering options are also available for focusing on certain types of metal, helping users direct their search toward a specific target category rather than treating every detected metal object alike.

Receiving and recording results

Detection feedback can include audio alerts or vibrations in addition to the visual display. These signals provide another way to notice a reported metal detection while using the app. After finding an object, users can save or share information about the detected metal object for further analysis, documentation, or showing the result to others. The app is described for hobbyists, treasure hunters, construction workers, and other users who need to locate metal objects.
