Metal Detector Science 101 By Loren Lemcke

[PSPR]

To help us figure out what effects the tones and signals we get in the field from our metal detectors, I present this brief video on the science that experiments with target surface area, orientation and topography.  Fascinating stuff.

If I put this in an inappropriate forum, Steve, please feel free to move it.  Thank you.

The same principle applies when you detect along the shaft of an iron nail as opposed to when you detect in a perpendicular angle to the nail. 

Try a masking test using a nail...coin...nail.   Change the orientation of the nails relative to the coin and watch what happens.  I always used the shaft approach when testing metal detectors for Kellyco years back as it was the tougher test.

Good video explanation of that principle....

Although this is a really nice video, it took me along time and a lot of digging to figure this stuff out, I'm not sure if it should all be explained in one video. 😉
