Imagine huge sites or woods and all what is needed to find metal-objects is
turning 360° around and scan the closer area around! Wouldn't it be fantastic?!
Of course all those LRL-dreamers (they are believing their own suggestions
and aren't able to provide the smallest proofs for their adventurous claims)
hunt this way already with very doubtful success but we need something real!
So the question is: What is really working directional and what not?!
It's clear that also usual MDs work somekind directional but not very far.
The range should be at least 10 meters for large objects.
What could work is some P.I. detector with high directional tesla coil or
something that sends out some radar-style pulse and listens if some
eddy-current loss caused by nearby metal-abjects are detectable.
Another way might be some special magnetometer that is able to
recognizes the complete 10 meter radius large magnetical field around
and sees if while walking over the area some closer coming object is
disturbing this field.
This way at least larger magnetical-metal-objects could be detected.
Another way would be some highly directional planar- or Yagi antenna
in combination with usual MD-circuit.
The result should be some steady EM-field which is reaching around
10meter distance like a 2 meter coil also would, but of course with
a much smaller and much more powerful special coil.
If a large enough metal-object crosses the long-range-EM-field of the detector
from already 10 meters while scanning 360° of the actual area the detector
is able and sensitive enough to see the difference.
Perhaps also some reflector shield has to be used so the detection
is focused just into one straight ahead direction.
btw. detecting stuff which is 10m away already absolutly is possible!
It depends just on the coils size and where are the coils are located.
The challenge will be creating a hand-holdable and not too heavy detector
which is already with pretty small and lightweight coils sensitive enough
to reach pretty far distant (ca. 5-15 meters) metal-objects.
Perhaps some directional magnetometer is the most simple solution,
because if some metal-object is crossing the line between user and the
earths-magnetical pole or if a metal object somewhere not too far
distracts the field-lines, this should be measurable from a far distance.
If someone knows already about such real working devices please inform us here!
