They said somewhere in yesterday's news that the director of the company had been arrested.
Good. But how is it possible to sell the obvious rubbish for so many years?
It even doesn't look like a dowsing rod at all.
Hopefully if the MOD considered buying any then they would have had to pass several tests to ensure that they worked.
When the navy buys a new weapon it has to pass both Harbour and Sea trials, in the case of the Phalanx system it was tested with live ammunition against a towed target.
I do not think that the explosives detector would have passed any trials.
