Metal & Gold Detector with Sound and Vibration is an application that detects the presence of metallic objects nearby by
measuring the magnetic field value. This useful utility tool uses the magnetic sensor built-in your smartphone and tablet
to show the magnetic field level in μT (microtesla).
EMF in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG. The sensor works in a way that in case some
metal is near, the value of the magnetic field in the app will increase which will confirm the presence of some metallic
The usability of app will help you identify any metal object in the area, behind walls, underground and other places. As
all metals generate a magnetic field and the strength of which can be measured with this tool.
Usage is quite simple. Just launch this application and move it around. In case of some presence of metal, you will see
the magnetic field level shown on the screen to get constantly fluctuating. Colorful line bars represent the intensity and
the number on top shows the value of the magnetic field level (EMF).
Reaching a certain limit the device will vibrate and makes sounds announcing that metal is close. You can calibrate and
from settings change the sensitivity of vibration and sound effects.
NOTE: The accuracy of readings by the tool depends entirely on the sensor in your mobile device and also note that due to
electromagnetic waves, the magnetic sensor may affect nearby electronic equipment.
🔳 App uses built-in magnetometer to measure electromagnetic field (EMF) level in your surroundings
🔳 The detected value of electromagnetic fields tells you if there are metal close
🔳 App works also through walls and floor so it can detect hidden electrical wires, studs and metals
🔳 The intensity of EMF is presented on a magnetic field intensity chart
🔳 Change the played sound and vibration option upon discovery of metal
