Metal Detector/EMF Magnetometer MF3

Metal Detector MF3 is an application which detects the presence of metal nearby by measuring the magnetic field value

Metal Detector MF3 allows identifying any metal object in the area, because all metals generate a magnetic field in which strength can be measured with this tool.

Detects metal object signals at a range of up to 25 cm.

Detect hidden electrical wires and metal objects in walls.

You can also use this app as a body scanner. A security scanner to detect metallic objects on people like smartphones, keys, and knives, etc. Use it in restrooms and changing rooms to detect hidden cameras.

How it works

•Metal Detector -- measures magnetic field value using a magnetic sensor that is built into your smartphone.

• After running this app if your phone shows high reading then immediately keep it away from everything to set it normal.

• The normal Electromotive force (EMF) field level is about 59μT (micro Tesla) or 590mG (Milli gauss); 1μT = 10mG. When any metal object like steel or iron is near, EMF reading will increase with a beef sound.

-- Attention! Every model of the smartphone has not a magnetic field sensor.--

--Metal detector cannot detect gold, silver, and coins made of copper--
