Metals Detector: Detect metals

FAQ – Metal Detector (EMF Meter) App

1. What is the Metal Detector app?

Metal Detector is a free app that turns your smartphone into a metal detecting tool using its built-in magnetic sensor. It measures nearby magnetic fields to detect metals, electronic waves, and other magnetic activity.

2. What can I use this app for?

• Detecting iron or steel objects

• Body scanning for magnetic materials

• Finding wires or pipes

• Measuring electromagnetic fields (EMF)

• Ghost detection (used by paranormal enthusiasts)

3. How does the app measure magnetic fields?

The app displays magnetic field strength in µT (microtesla), mG (milligauss), or G (gauss). Environmental magnetic fields usually range from 30–60 µT (0.3–0.6 G). When metal is nearby, the reading increases above this range.

4. Can it detect all metals?

No. The app can only detect ferrous metals (iron and steel) because they are magnetic. Non-ferrous metals like gold, silver, and aluminum do not produce a magnetic field and cannot be detected.

5. Do all smartphones work with this app?

No. Your device must have a magnetic sensor (magnetometer). Without it, the app cannot function. Check your phone specifications before downloading.

6. What can affect accuracy?

Electronic devices such as TVs, laptops, radios, and microphones can interfere with the magnetic sensor. For the best results, keep a distance from electronics when using the app.

7. Can this app be used for ghost detection?

Some paranormal investigators use EMF readings from this app to detect anomalies in magnetic fields. While there is no scientific proof linking ghosts to EMF changes, users find it useful for “ghost hunting” as a fun experiment.

8. Is this app free?

Yes. Metal Detector is completely free to download and use.

9. How do I interpret the readings?

• Normal environment: 30–60 µT (0.3–0.6 G)

• Metal nearby: values above 60 µT (0.6 G)
  The higher the reading, the stronger the magnetic field detected.

10. Can this app replace a professional metal detector?

No. While it’s useful for casual detection, it cannot fully replace professional metal detecting equipment, especially for non-magnetic metals.
