Some developers are taking advantage of the interference that certain metallic and electronic objects cause in the compass incorporated in the new iPhone 3GS to create applications that simulate “metal detectors”.

Metal detector on iPhone

Earlier today I tested one of them, but I found the result so weak that I gave up talking. However, as some readers are sending the suggestion, I decided to publish the video I made.

The tested application was the Metal Detector Pro, which is free on the App Store. It only works on iPhone 3GS and theoretically sounds an alarm every time you approach a metal. But in our tests, he ended up playing too when making sudden movements. In other cases, he didn’t get to play every time he came close to a metal. In practice, even Love Detector it was more accurate than him.

I didn’t like it. But to impress someone, in certain situations, it can do.
