One more to prove the concept

[hung]

The concept developed by Rangertell has made school.
I refer to the inductively transmit-receive aproach employing an antenna aligning to the signal lines emitted by the EM field of the objects. In this case, there are two of them.

A german manufacturer is using the same method for quite some time and I just thought it was worth to mention it.

In place of the calculator, another signal generator but with fixed frequencies.

Unlike the RT unit which allows parameters to be keyed in to receive the magnetic response of shape, depth etc. of the target, making it more versatile, the Tomdec unit has only fixed frequencies to locate the targets and it's built more properly in my view as it tends to cancel any ideomotor effect which tends to interfere in the detection when the user is unexperienced.

I just see their frequencies are not the most adequate, but as this device has been around for sometime, maybe they have upgraded them.

Nice reading to all.
