"The Mine Kafon has just been tested by the Dutch Explosive Ordnance Disposal Unit, which has concluded that it is not suitable for mine clearance (which requires a more systematic approach), but at $50 each could be used as a cheap and safe way to identify dangerous areas that need demining."
All this discussion is because of an over-enthusiastic headline, not what the tool is actually intended for.
If you manage to clear a field such that there is a single mine in it, it will likely become safer to march through than avoid - there are plenty of other things that can kill you, and they must be triaged in war time.
However, if you take that same field after the war is over and put a farmer on it, it's basically a matter of time until he steps on it. His only chance is that an animal blows it up, or the mine is defective.
Therefore, if it's not suitable for military clearing, it is even less suitable for civilian purposes (except for figuring out what needs to be cleared, as they say).
[Added] I’m talking from a US perspective, but it seems plausible that most developed country militaries spend on technology when in time of peace.
