This is a short demonstration of our Android Metal Detector App in use. This free app allows you to use any Android phone with an in-built magnetometer (compass) to find ferrous metal objects such as iron or steel.
Two ferrous metal objects are buried in the sand in this demo. By simply moving the phone until you hear the highest pitch tone and/or the green line on the screen goes as low as it can you are over the buried object.

Please note this app will not find gold, silver or nickel alloy coins.
