The data map that is generated is about the same regardless of what altitude, but at satellite heights, the resolution is not as good as when measuring from a plane or on the ground, which give the same resolution. The probe consists of a lead tube that is open at one end to expose a scintillator crystal. While the crystal is shielded from light, the open lead end allows gamma and alpha radiation to pass through the light filter. The purpose of the lead tube is to shield gamma from entering at the sides, and only enter through the open end. A photomultiplier behind the crystal converts tiny flashes of light to electrical signals which are analyzed, then sent to a counter to determine how many counts are coming from a gold isotope (or other materials that are being searched for). This device will give meaningful data only when it is pointed downward and used to make a survey of a plot of land. In theory, you may be able to rig it to work for searching an area at an angle different than down, but I have not heard of it being used in that way.
The signals are extremely weak as you say. Dr. Bickel told me it is best to use this detector at times of the day when the solar activity is low. Otherwise the noise from the solar activity interferes with getting reliable readings. He recommended mornings before noon, around 10am for the work he did in the western USA and in Mexico.

It would be valuable to know whether the detector works also at other directions than perpendicular to earth surface. I stumble always upon this feat-
that it needs to be directly above the source- in many pre WWII books. dont get me wrong. having a low flying plane with this device on board and flying over a suspect area over all the rocks, soil lakes and trees and get accurate data regardless of the terrain is really extremely helpful and wonderful but it is not to be compared with the ability to "point-scan" and area, i.e. stand in a forest, aim the device forward and rotate around you left or right until you find a signal.
Actually the "point+scan" ability should work just as well for the Bickel device. If point and scan does not work than, this means something big and important, (unnoticed by many) and perhaps confirming one cruicial point one more time during my research: those so called gamma radiations of the atom that are detected are not coming from the atom, they are coming from outer space. rays of extreme penetration imparting earth and all of its elements interacting with the atom. Obviously the highest penetration happens at 90 degrees from surface. Lots of materials indicate this as well or Something close to this. These are called vertical beams emanating from all elements. And that is what dowsers feel.
Nothing is written in stone yet though
