<div class="tab-content-content">Metal Detector is an app that is part of the Smart Tools collection. It requires a magnetic sensor to work properly, and if it doesn't work, users should check their device's specifications. The app measures the magnetic field with an embedded magnetic sensor, and when any metal is near, the magnetic field level will increase. The app is simple to use, and users can find electrical wires in walls and iron pipes in the ground. Ghost hunters have also experimented with the app as a ghost detector, but its accuracy depends on the device's magnetic sensor and is affected by electronic equipment due to electromagnetic waves.</div><div class="tab-content-content"></div><div class="tab-content-content">The app's main features include an alarm level, beep sound, sound effect on/off, and material design. The pro version has additional features such as no ads, a compass, sharing GPS location, Qibla finder, and car locator. However, the app cannot detect gold, silver, and coins made of copper as they are classified as non-ferrous metal that has no magnetic field. Users who want more tools can download Smart Compass Pro and Smart Tools 2 package.
