【實用工具app】Metal Detector LCD|最夯免費app-綠色工廠好玩App

**THIS WILL ONLY WORK FOR DEVICES THAT HAVE A MAGNETICS SENSOR**

Use your phone's built-in magnetics sensor to detect metals that distort the natural magnetic field.

Technically speaking only metals that contain ferrimagnetic elements such as iron, nickel and cobalt will register variations onscreen.

When a ferrimagnetic metal object obscures the natural magnetic field and the result is shown realtime on the graph. Different shapes and sizes of metal contain ferrimagnetic elements will all register in a different ways; long thin items like screwdrivers seem to have to greatest effect so have fun experimenting!

How to use: Install the app and then press the Power Button on screen to get going. Tapping on the graph will toggle between 'Continuous Autoscale Mode' and 'Stepped Autoscale Mode', see which one you prefer. If you want more sensitivity then you can toggle the 'Boost Sensitivity' option in the menu. For people who have a slow device you can slow down the update using the 'Change Update Rate' option, likewise if you have a really quick device you can speed up the detection rate. There is also an option to keep the screen 'alive' whilst detecting. This app can be Shared via Facebook, Google+ and Twitter.

This only works on devices that have a built in magnetics sensor. If your device doesn't have one then you will receive an error message.
