I had the opportunity to watch this 'vision' detector video shot at the show.
1 - The guy who was demonstrating the detector was always complaining about high electromagnetic interference (EMI) present.
Wow... So, ordinary MDs also suffer from the same crap that supposedly plages Dowsing based LRLs...
2 - The detector could not tell the difference between a pull tab and a 5 cent nickel coin.
He then explained that by lowering some digit function values this could be done, and etc. But he gave no demonstration for that...
Hummm....
Sounds like a real LRL to me...
