From what I recall.
The groundhog and FK-7 can also find Alazhi,
But the Alazhixazha only finds Alazhi.
The way prospection works is within a range, if the number at the end of the prospection calcs is within the range of a certain material, then you get that material. The Alazhixazha narrows that range to Alazhi or Nothing.
Again, this is all speculation from experience... best asking the Devs who can actually see the code.
