According to the designer, he envisions this ball as a good way to find minefields. Apparently, soldiers can spend days looking for mines in a place where there may not be any. He think that you could let this device loose and let it look for the fields. Then when one mine is found, then you could bring in the mine sweeping teams. He doesn't claim that it will do a comprehensive sweep.
