Thanks for the info. Of course our main goal here is not locating living ground-animals but deep buried treasures.
So the question is how good such devices are to handle for ground-scanning, how deep do they work
under what kind of soil situation etc.

How good does it shows the not living items inside a room sealed with concrete-walls and similar things.

I can imagine that at deserts with huge sand-dunes it may work pretty well but not at ground full of rocks and boulders.
Would be interesting what kind of picture it shows and if there is everything - cavity, metalic and mineralic stuff to see.

thx for the info, I will check out that material.

Compared to the other GPRs this technology seems to be able to show "real" pictures
which is good if it comes to decision worth digging or not.

However the prices are beyond good and evil and seems so far they are
not made very well handable for vertically ground-scanning.
