This video is a step into the right direction - but we need alot more of these.
Is this a metal plate directly under the handle for shielding?
Is there a knob for adjusting the beeping volume?
btw. this random beeping really is irritating.
A raise in the tone-frequency would be better or a visual instrument like a VU-Meter.
What means this "walk from north to south"?
That the magnetic particles "flying" from south to north and get weakened or distracted by the long time ago buried object, creating some wind-shadow similar effect that you can detect? In other words some kind of "hole or distortion in the magnetic field"?
Perhaps this also distorts the electrostatic field, but I doubt that there are flying any ions through the air.
by the way there exists some (new?) Mineoro demonstration video:

and this "deep & center" or whats the exact name thing is really interresting.
Anyway:
More videos please, not only from treasure places, but also from authentic test sessions.
