Mike ,how about pinpointing a massive test target?
Do you have any experience on this, using the Magnacast along with the scan gun?
Usually, using a classic MFD configuration, (signal generator + coil for transmitter + L-rods for line detection) we have a significant deviation.
The pinpoint accuracy for small targets(2-3 coins) is ok, but if we increase the test target mass, the L-rods indicates that the target is several meters away.
For example in our test site, a 48 Kilogram copper target has a deviation at about 25 meters.
Also,a extra deviation is added, according to the years which the target is buried.
So, i think there is no way to pinpoint a real treasure using the classic L-rods.
The human body as part of the receiver ,acts most like a differential amplifier.
It is indeed very sensitive, but i think that senses the degree of field changes, something like the first derivative and not the absolute values.
And furthermore, every human as a receiver, has his own level of sensitivity.
I have tried to chart the sensitivity of about 20 MFD users and the distribution of sensitivity looks like a Gaussian ,but the sample is small to be sure.
