Metal Detector

About Metal Detector Android App

A simple metal detector, that displays the ambient magnetic field in micro Tesla (µT).

- Set your favourite layout colors.
- 3 different designs to visualize the measurement.
- Vibration or sound feedback when a certain value is reached.
- Variable sensor's sensitivity.
- Values of the x, y and z axis can be displayed.
- Optionally the display is always kept active.
- Landscape and portrait mode.
- App can be moved to sd card.

Permissions:
VIBRATION: You can choose to get a vibrating feedback if the magnetic field reaches a certain value.
INTERNET and ACCESS_NETWORK_STATE are only used to show the ad. Therefore the app is for free. Read the privacy policy to get more information about advertisement and your data.

Info:
- The accuracy of the measurement depends on the sensors of your device.
- From time to time your device should be calibrated by drawing an eight in the air with your device.
- The magnetic field of the earth ranges from 30 to 60 µT. Magnets and electric fields influence the measurement.
- Too strong magnetic fields or vibration may lead to unusual high values permanently. This is not because of the app, but because of the sensors! Try to calibrate your device or hold it close to a slightly higher magnetic field (less than 200 µT) for a short time.
