App Description

★ ★ ★ ★ ★ ★ READY FOR iPHONE 4 S ★ ★ ★ ★ ★ ★

The iphone has a built-in compass that can be manipulated to be used as a metal detector in multiple useful ways

How To Use:
1. Point the edge with the compass (arrow) against your object
2.Run the app
3.Watch the numbers and the graph
4.The higher the number and graph go, the more metal you are close to



The simplest form of a metal detector consists of an oscillator producing an alternating current that passes through a coil producing an alternating magnetic field. If a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal, and this produces an alternating magnetic field of its own. If another coil is used to measure the magnetic field (acting as a magnetometer), the change in the magnetic field due to the metallic object can be detected.
The first industrial metal detectors were developed in the 1960s and were used extensively for mining and other industrial applications. Uses include de-mining (the detection of land mines), the detection of weapons such as knives and guns, especially in airport security, geophysical prospecting, archaeology and treasure hunting. Metal detectors are also used to detect foreign bodies in food, and in the construction industry to detect steel reinforcing bars in concrete and pipes and wires buried in walls and floors.

Compatible with: iPhone 3gs
iPhone 4
iPad (original)
iPad 2


There are a multitude of uses for something like this, just a few are:

• Treasure Hunting

• Geocaching

• Searching for studs in a wall (prior to putting up a picture perhaps) finding nails in a floor

• Testing if an object (say a strange rock) is magnetic

• Theoretically you could even tie your iPhone or iPad to a pole and use it as a conventional metal detector.
